AMMONIUM POLYPHOSPHATE
Ammonium polyphosphate is an organic salt of polyphosphoric acid and ammonia.
As a chemical, Ammonium polyphosphate is non-toxic, environmentally friendly and halogen-free.
It is most commonly used as a flame retardant, selection of the specific grade of ammonium polyphosphate can be determined by the solubility, Phosphorus content, chain length and polymerization degree.

CAS: 68333-79-9
MF: H12N3O4P
MW: 149.086741
EINECS: 269-789-9

The chain length (n) of this polymeric compound can be linear or branched.
Depending on the polymerization degree, there are two main families of ammonium polyphosphate: Crystal phase I APP (or APP I), and Crystal phase II APP (or APP II).
Ammonium polyphosphate phase I has a short and linear chain (n < 100), it is more water sensitive (hydrolysis) and less thermally stable; actually it begins to decompose at temperatures above 150 °C.
The second family of Ammonium polyphosphate is the APP Phase II; which has an high polymerization degree, with n>1000, its structure is cross linked (branched), and Ammonium polyphosphate is an high-quality non-halogenated flame retardant.
APP phase II, Ammonium polyphosphate, has an higher thermal stability (the decomposition starts at approximately 300°C) and lower water solubility than APP I.

Ammonium polyphosphates are liquid fertilizers with compositions up to 11-37-0, manufactured by the reaction of anhydrous ammonia with superphosphoric acid.
Superphosphoric acid is made by the concentration of regular wet-process acid up to P2O5 concentrations of 78%.
Granular polyphosphates suitable for bulk blending are made by reacting ammonia with regular wet process acid of 52% P2O5 content and using the heat of reaction to drive off water to produce a phosphate melt of 10-43-0, with about 40% of the phosphorus in the polyphosphate form.

Ammonium polyphosphate is an inorganic salt of polyphosphoric acid and ammonia containing both chains and possibly branching.
Ammonium polyphosphate's chemical formula is H(NH4PO3)nOH showing that each monomer consists of an orthophosphate radical of a phosphorus atom with three oxygens and one negative charge neutralized by an ammonium cation leaving two bonds free to polymerize.
In the branched cases some monomers are missing the ammonium anion and instead link to three other monomers.

Ammonium Polyphosphate is a stable and non-volatile compound.
Ammonium polyphosphate comes under the category of halogen free flame retardants and works as a smoke suppressant too.
Ammonium Polyphosphate is very cost effective when compared to other halogen free systems.
Lower loading into polymers ensures good retention of mechanical and electrical properties and excellent flow.
Allowing plastics to exhibit excellent processability, Ammonium Polyphosphate is used as an efficient flame retardant in the furniture industry and for interior fabrics for the automotive industry.

The properties of ammonium polyphosphate depend on the number of monomers in each molecule and to a degree on how often it branches.
Shorter chains (n < 100) are more water sensitive and less thermally stable than longer chains (n > 1000), but short polymer chains (e.g. pyro-, tripoly-, and tetrapoly-) are more soluble and show increasing solubility with increasing chain length.

Ammonium polyphosphate can be prepared by reacting concentrated phosphoric acid with ammonia. However, iron and aluminum impurities, soluble in concentrated phosphoric acid, form gelatinous precipitates or "sludges" in ammonium polyphosphate at pH between 5 and 7.
Other metal impurities such as copper, chromium, magnesium, and zinc form granular precipitates.
However, depending on the degree of polymerization, ammonium polyphosphate can act as a chelating agent to keep certain metal ions dissolved in solution.
Ammonium polyphosphate is used as a food additive, emulsifier, (E number: E545) and as a fertilizer.

Ammonium polyphosphate is also used as a flame retardant in many applications such as paints and coatings, and in a variety of polymers: the most important ones are polyolefins, and particularly polypropylene, where APP is part of intumescent systems.
Compounding with APP-based flame retardants in polypropylene is described in.
Further applications are thermosets, where Ammonium polyphosphate is used in unsaturated polyesters and gel coats (APP blends with synergists), epoxies and polyurethane castings (intumescent systems).
Ammonium polyphosphate is also applied to flame retard polyurethane foams.

Ammonium polyphosphates used as flame retardants in polymers have long chains and a specific crystallinity (Form II).
They start to decompose at 240 °C to form ammonia and phosphoric acid.
The phosphoric acid acts as an acid catalyst in the dehydration of carbon-based poly-alcohols, such as cellulose in wood.
The phosphoric acid reacts with alcohol groups to form heat-unstable phosphate esters.
The esters decompose to release carbon dioxide and regenerate the phosphoric acid catalyst.
In the gas phase, the release of non-flammable carbon dioxide helps to dilute the oxygen of the air and flammable decomposition products of the material that is burning.
In the condensed phase, the resultant carbonaceous char helps to shield the underlying polymer from attack by oxygen and radiant heat.
Use as an intumescent is achieved when combined with starch-based materials such as pentaerythritol and melamine as expanding agents.
The mechanisms of intumescence and the mode of action of Ammonium polyphosphate are described in a series of publications.

PEG-4 is used in pressure sensitive and thermoplastic adhesives.
PEG-4 is a family of linear polymers formed by a base-catalyzed condensation reaction with repeating ethylene oxide units being added to ethylene.
The molecular formula is (C2H4O)multH2O where mult denotes the average number of oxyethylene groups.
The molecular weight can range from 200 to several million corresponding to the number of oxyethylene groups.
The higher-molecular-weight materials (100 000 to 5 000 000) are also referred to as polyethylene oxides.

The average molecular weight of any specific PEG-4 product falls within quite narrow limits (°5%).
The number of ethylene oxide units or their approximate molecular weight (e.g., PEG-4 or PEG-200) commonly designates the nomenclature of specific PEG-4.
PEG-4 with amolecular weight less than 600 are liquid, whereas those of molecular weight 1000 and above are solid.
These materials are nonvolatile, water-soluble, tasteless, and odorless.
They are miscible with water, alcohols, esters, ketones, aromatic solvents, and chlorinated hydrocarbons, but immiscible with alkanes, paraffins, waxes, and ethers.

PEG-4 is the product of the catalysed reaction between ethylene oxide and
water.
The polymerisation reaction is controlled so that the average molecular weight is in the range 190 – 210.
PEG-4, at room temperature, is a clear, hygroscopic liquid, which possesses a
characteristic low vapour pressure and excellent lubricity.
PEG-4 is totally soluble in water and in most organic solvents except aliphatic hydrocarbons.
At high temperatures and in the presence of air PEG-4 will undergo decomposition.
However, improved stability can be gained by the use of antioxidants.
As PEG-4 contains two terminal hydroxyl groups it can be used in polyurethane and esterification reactions.

The crude product was washed with ethanol and acetic acid was added to adjust the pH value to 4-6. added glyoxal to crosslink and aging, washed with water fast, finally centrifugal dehydration, dried, milled, obtained low salt Hydroxyethyl cellulose.

A purified form of cellulose is reacted with sodium hydroxide to produce a swollen alkali cellulose, which is chemically more reactive than untreated cellulose.
The alkali cellulose is then reacted with ethylene oxide to produce a series of Tylose H 20 P2 ethers.
The manner in which ethylene oxide is added to cellulose can be described by two terms, the degree of substitution (DS) and the molar substitution (MS).
The DS designates the average number of hydroxyl positions on the anhydroglucose unit that have been reacted with ethylene oxide.
Since each anhydroglucose unit of the cellulose molecule has three hydroxyl groups, the maximum value for DS is 3. MS is defined as the average number of ethylene oxide molecules that have reacted with each anhydroglucose unit.
Once a hydroxyethyl group is attached to each unit, it can further react with additional groups in an end-to-end formation.
This reaction can continue and there is no theoretical limit for MS.

Preparation
Tylose H 20 P2 is prepared from alkali cellulose and ethylene oxide.
Tylose H 20 P2 may be noted that the hydroxyethyl group itself can react with ethylene oxide so that side-chains of varying length may be present in the product.
Commercial materials generally contain between 1.4 and 2.0 ethylene oxide residues per glucose residue and have a degree of substitution of about 0.8-1.0.

Toxicology
Considered to be non toxic.
Use as a food additive indicates good tolerance of small amounts, but excessive amounts or overuse may bring irritant and /or harmful effects.
Polysaccharides are not substantially absorbed from the gastrointestinal tract but may produce a laxative effect.

(Hydroxyethyl)methacrylate, Normal Grade, in the form of a colorless, clear liquid, is an industrial solvent that can be used in automotive coatings and primers.
Because of its vinyl double bond, this product can copolymerize with other monomers to produce copolymers with hydroxy groups.


(Hydroxyethyl)methacrylate is an enoate ester that is the monomethacryloyl derivative of ethylene glycol.
(Hydroxyethyl)methacrylate has a role as a polymerisation monomer and an allergen.
(Hydroxyethyl)methacrylate is functionally related to an ethylene glycol and a methacrylic acid.


(Hydroxyethyl)methacrylate is a hydroxyester compound and a resin monomer used in desensitizing dentin.
By applying 2-hydroxyethyl methacrylate locally to sensitive teeth, sensitive areas in the teeth get sealed and block the dentinal tubules at the dentin surface from stimuli that cause pain.
This prevents excitation of the tooth nerve and relieves pain caused by tooth hypersensitivity.




(Hydroxyethyl)methacrylate is an ester of Methacrylic acid and is used as a raw material component in the synthesis of polymers.
(Hydroxyethyl)methacrylate forms a homopolymer and copolymers.
Copolymers of (Hydroxyethyl)methacrylate can be prepared with (meth)acrylic acid and its salts, amides, and esters, as well as (meth)acrylates, acrylonitrile, maleic acid esters, vinyl acetate, vinyl chloride, vinylidene chloride, styrene, butadiene, and other monomers.

(Hydroxyethyl)methacrylate, easily entering into the reaction of accession with a wide range of organic and inorganic substances, is used for the synthesis of organic low molecular weight substances.



Clear colorless, easily flowable liquid monomer with a pungent, sweet odor.
(Hydroxyethyl)methacrylate comprises of a polymerizable methacrylate functional group in one end and a reactive hydroxyl group at the other end.
(Hydroxyethyl)methacrylate easily dissolves in water and has relatively low volatility.

(Hydroxyethyl)methacrylate copolymerizes readily with a wide variety of monomers, and the added hydroxyl groups improve adhesion to surfaces, incorporate cross-link sites, and impart corrosion, fogging, and abrasion resistance as well as contribute to low odor, color, and volatility.





SYNTHESIS OF (HYDROXYETHYL)METHACRYLATE:
Hydroxyethylmethacrylate was first synthesized around 1925.
Common methods of synthesis are:[5]
reaction of methacrylic acid with ethylene oxide;
esterification of methacrylic acid with a large excess of ethylene glycol.

Both these methods give also some amount of ethylene glycol dimethacrylate.
During polymerization of hydroxyethylmethacrylate, it works as crosslinking agent.[5]


PROPERTIES OF (HYDROXYETHYL)METHACRYLATE:
Hydroxyethylmethacrylate is completely miscible with water and ethanol, but its polymer is practically insoluble in common solvents.
Its viscosity is 0.0701 Pa⋅s at 20°C[6] and 0.005 Pa⋅s at 30°C.[3]
During polymerization, it shrinks by approximately 6%.[6]


APPLICATIONS OF (HYDROXYETHYL)METHACRYLATE:
Contact lenses[edit]
In 1960, O. Wichterle and D. Lím[7] described its use in synthesis of hydrophilic crosslinked networks, and these results had great importance for manufacture of soft contact lenses.

Polyhydroxyethylmethacrylate is hydrophilic: it is capable of absorbing from 10 to 600% water relative to the dry weight.
Because of this property, it was one of the first materials to be used in the manufacture of soft contact lenses.

Use in 3D printing
Hydroxyethylmethacrylate lends itself well to applications in 3D printing as it cures quickly at room temperature when exposed to UV light in the presence of photoinitiators.
It may be used as a monomeric matrix in which 40nm silica particles are suspended for 3D glass printing.[9]
When combined with a suitable blowing agent such as BOC anhydride it forms a foaming resin which expands when heated.[10]

Other
In electron microscopy, later in light microscopy, hydroxyethylmethacrylate serves as an embedding medium.
When treated with polyisocyanates, polyhydroxyethylmethacrylate makes a crosslinked polymer, an acrylic resin, that is a useful component in some paints.

In addition to 1,2-Dibromoethane tumor-causing capabilities in rats and mice; 1,2-Dibromoethane has been documented to cause changes in sperm morphology in bulls.

Spermatids appear to be the target for this compound and 1,2-Dibromoethane has been shown to affect spermatogenesis in rat, bulls and rams and to affect fertility in fowl.
Human studies indicate that 1,2-Dibromoethane may harm sperm and decrease fertility.
While 1,2-Dibromoethane is a reproductive toxin, 1,2-Dibromoethane does not appear to be teratogenic.

1,2-Dibromoethane is a manufactured chemical.
1,2-Dibromoethane also occurs naturally in small amounts in the ocean where 1,2-Dibromoethane is formed, probably by algae and kelp.

1,2-Dibromoethane is a colorless liquid with a mild, sweet odor.
Other names for 1,2-dibromoethane are ethylene dibromide, EDB, and glycol bromide.
Trade names include Bromofume and Dowfume.

1,2-Dibromoethane has been used as a pesticide in soil, and on citrus, vegetable, and grain crops.
Most of these uses have been stopped by the Environmental Protection Agency (EPA) since 1984.

Another major use was as an additive in leaded gasoline.
However, since leaded gasoline is now banned, 1,2-Dibromoethane is no longer used for this purpose.
1,2-Dibromoethane is uses today include treatment of logs for termites and beetles, control of moths in beehives, and as a preparation for dyes and waxes.

1,2-Dibromoethane is a colorless liquid with a strong odor that was once used as a pesticide.
In addition to being used to kill insects and other pests, 1,2-Dibromoethane was also added to gasoline.

1,2-Dibromoethane is mostly manmade but may be found naturally in the ocean in very small amounts.
1,2-Dibromoethane vaporizes and easily and will mix easily with water.

Small amounts of 1,2-Dibromoethane can be found in soil near hazardous waste sites.
1,2-Dibromoethane can also be found on agricultural fields or in areas once used for farming.

While 1,2-Dibromoethane remains in groundwater and soil for a long time, 1,2-Dibromoethane breaks down quickly in the air.
Generally, environmental levels are very low.

In the 1970s and early 1980s, 1,2-Dibromoethane was used to kill insects and worms on fruits, vegetables and grain crops.
1,2-Dibromoethane was also used to protect grass on golf courses and as an additive in leaded gasoline.
Most of these uses stopped in 1984.

1,2-dibromoethane is a largely obsolete insecticide.

Preparation and Use of 1,2-Dibromoethane:
1,2-Dibromoethane is produced by the reaction of ethylene gas with bromine, in a classic halogen addition reaction:
CH2=CH2 + Br2 → BrCH2–CH2Br

Historically, 1,2-dibromoethane was used as a component in anti-knock additives in leaded fuels.
1,2-Dibromoethane reacts with lead residues to generate volatile lead bromides, thereby preventing fouling of the engine with lead deposits.

Pesticide:
1,2-Dibromoethane has been used as a pesticide in soil and on various crops.
The applications were initiated after the forced retirement of 1,2-dibromo-3-chloropropane (DBCP).

Most of these uses have been stopped in the U.S.
1,2-Dibromoethane continues to be used as a fumigant for treatment of logs for termites and beetles, for control of moths in beehives.

Reagent:
1,2-Dibromoethane has wider applications in the preparation of other organic compounds including those carrying modified diazocine rings and vinyl bromide that is a precursor to some fire retardants.

In organic synthesis, 1,2-dibromoethane is used as a source of bromine to brominate carbanions and to activate magnesium for certain Grignard reagents.
In the latter process, 1,2-dibromoethane reacts with magnesium, producing ethene and magnesium bromide, and exposes a freshly etched portion of magnesium to the substrate.

Methods of Manufacturing of 1,2-Dibromoethane:
1,2-Dibromoethane is made from ethylene and bromine.
1,2-Dibromoethane is also made from acetylene and hydrobromic acid.

1,2-Dibromoethane is manufactured via uncatalyzed, liquid-phase bromination of ethylene.
Gaseous ethylene is brought into contact with bromine by various methods, allowing for dissipation of the heat of the reaction.

The commercial manufacturing process is carried out in a glass column reactor consisting of a lower packed section and an unpacked upper section containing a number of superimposed, high-capacity, coil heat exchangers.
Liquid bromine is continuously added above the packed section while a slight excess of ethylene is continuously fed countercurrently from the bottom of the packed section.

The exothermic reaction between ethylene and bromine occurs in the liquid phase on the surfaces of the cooling coils, and heat is removed at a rate sufficient to maintain a maximum temperature of 100 °C and the section of the column.
Some reaction also occurs in the gas phase above the bromine feed where product is condensed and separated from the vent gas (ethylene, hydrogen bromide, and interact material).

As the crude liquid product passes downward through the packed section, 1,2-Dibromoethane provides a contacting surface for rising ethylene to convert any residual dissolved bromine.
Ethylene dibromide is continuously withdrawn from the reactor into a hold-up tank where 1,2-Dibromoethane is irradiated with ultraviolet light to eliminate minor amounts of unconverted starting materials.

Several million tonnes are produced annually.
The common name is derived from the turpentine-producing tree Pistacia terebinthus and phthalic acid.

1,4-benzenedicarboxylic acid is used for the production of polyesters with aliphatic diols as the comonomer.
The polymer is a high-melting, crystalline material forming very strong fibers.

1,4-benzenedicarboxylic acid is an organic compound with formula C6H4(CO2H)2.
This white solid is a commodity chemical, used principally as a precursor to the polyester PET, used to make clothing and plastic bottles.

1,4-benzenedicarboxylic acid is the largest volume synthetic fiber and the production of 1,4-benzenedicarboxylic acid is the largest scale operated process based on a homogeneous catalyst.
More recently the packaging applications (PET, the recyclable copolymer with ethylene glycol) have also gained importance.

1,4-benzenedicarboxylic acid is produced from -xylene by oxidation with oxygen.
The reaction is carried out in acetic acid and the catalyst used is cobalt (or manganese) acetate and bromide.

Phthalic anhydride is made from naphthalene or -xylene by air oxidation over a heterogeneous catalyst.
The main application of phthalic anhydride is in the dialkylesters used as plasticizers (softeners) in PVC.
The alcohols used are, for instance, 2-ethylhexanol obtained from butanal, a hydroformylation product.

1,4-benzenedicarboxylic acid is an industrially important aromatic acid, almost exclusively used as starting material for saturated polyester, mainly poly(ethylene terephthalate) (> 90%).
1,4-benzenedicarboxylic acid is almost entirely made by oxidation of petro-derived p-xylene.

Pathways toward biobased p-xylene or 1,4-benzenedicarboxylic acid mainly focus on carbohydrates such as cellulose or hemicellulose.
Nonetheless, Yan and colleagues were the first to report a three-step process from corn stover lignin to 1,4-benzenedicarboxylic acid.

Starting from depolymerized RCF lignin oil, 1,4-benzenedicarboxylic acid includes (i) a Mo on carbon catalyzed demethoxylation, (ii) a carbonylation of the obtained n-alkylphenol with CO by a homogeneous Pd-catalyst, and finally (iii) an oxidation of the 4-n-propylbenzoic acid to terephathalic acid by a Co-Mn-Br catalyst under O2 pressure.
The demethoxylation was performed on crude lignin oil, which was obtained from corn stover by RCF in methanol over a Ru on carbon catalyst.

The 4-n-alkylphenol yield after demethoxylation, starting from a guaiacyl and syringyl monomer mixture, was 65.7 mol% based on the total monomers (16.1 wt% based on lignin content).
Interestingly, they found that the Mo catalyst also removed para-substituted ester group from phenolic monomers in addition to 1,4-benzenedicarboxylic acid demethoxylation activity.

Next, CO was inserted using carbonylation of 4-n-alkylphenols by a homogeneous Pd catalyst.
To increase reactivity, 4-n-alkylphenol triflates were formed prior to carbonylation.

On average, a 75 mol% yield was obtained for all 4-alkylphenols (methyl, ethyl and n-propyl) toward the 4-alkylbenzoic acid.
Finally, the oxidation yield of 4-alkylbenzoic acid mixture toward 1,4-benzenedicarboxylic acid was 60 mol%.

Remarkably, 1,4-benzenedicarboxylic acid could be obtained from the reaction mixture by simple filtration and washing with water.
Looking at the overall process, the 1,4-benzenedicarboxylic acid yield starting from the lignin oil was 30 mol% and corresponds to 15.5 wt% based on corn stover lignin content.

1,4-benzenedicarboxylic acid is one isomer of the three phthalic acids.
1,4-benzenedicarboxylic acid finds important use as a commodity chemical, principally as a starting compound for the manufacture of polyester (specifically PET), used in clothing and to make plastic bottles.

1,4-benzenedicarboxylic acid is also known as Terephthalic acid, and 1,4-benzenedicarboxylic acid has the chemical formula C6H4(COOH)2.
1,4-benzenedicarboxylic acid has recently become an important component in the development of hybrid framework materials.

1,4-benzenedicarboxylic acid is a benzenedicarboxylic acid carrying carboxy groups at positions 1 and 4.
One of three possible isomers of benzenedicarboxylic acid, the others being phthalic and isophthalic acids.

1,4-benzenedicarboxylic acid is a conjugate acid of a terephthalate(1-).
1,4-benzenedicarboxylic acid is one isomer of the three phthalic acids.

1,4-benzenedicarboxylic acid finds important use as a commodity chemical, principally as a starting compound for the manufacture of polyester (specifically PET), used in clothing and to make plastic bottles.
1,4-benzenedicarboxylic acid is also known as Terephthalic acid, and 1,4-benzenedicarboxylic acid has the chemical formula C6H4(COOH)2.

Process for Preparation of 1,4-benzenedicarboxylic acid:
One of the world’s most widely produced polymers, poly(ethylene terephthalate) (PET), is synthesized via condensation polymerization of ethylene glycol with 1,4-benzenedicarboxylic acid and small amounts of isophthalic acid.
Current industrial production of 1,4-benzenedicarboxylic acid and isophthalic acid uses petroleum-derived xylenes as starting materials.

The cost and availability of petroleum varies wildly and unpredictably.
In order to stabilize costs associated with the synthesis of 1,4-benzenedicarboxylic acid and isophthalic acid, alternative feedstocks must be made available.

A reaction sequence has been elaborated that addresses this need.
The starting materials, acrylic acid and isoprene, are reacted in a solvent-free cycloaddition catalyzed by an inexpensive Lewis acid catalyst.

Vapor phase aromatization of the resulting cycloadducts affords para- and meta-toluic acid, which are oxidized to 1,4-benzenedicarboxylic acid and isophthalic acid, respectively.
Both acrylic acid and isoprene are commercially synthesized from petroleum or shale gas but may also be synthesized from biobased feedstocks.

Thus, by diversifying available feedstocks, costs associated with commercial 1,4-benzenedicarboxylic acid and isophthalic acid synthesis are stabilized.
Moreover, this reaction sequence is the only one reported in the literature to produce both 1,4-benzenedicarboxylic acid and isophthalic acid for the manufacture of PET.

Biodegradation of 1,4-benzenedicarboxylic acid:
In Comamonas thiooxydans strain E6, 1,4-benzenedicarboxylic acid is biodegraded by a pathway starting at terephthalate 1,2-dioxygenase into protocatechuic acid, a common natural product.
Combined with the previously known PETase and MHETase, a full pathway for PET plastic degradation can be engineered.

Properties of 1,4-benzenedicarboxylic acid:
1,4-benzenedicarboxylic acid is almost insoluble in water, alcohol and ether; 1,4-benzenedicarboxylic acid sublimes rather than melting when heated.
This insolubility makes 1,4-benzenedicarboxylic acid relatively awkward to work with, and up until around 1970 much crude 1,4-benzenedicarboxylic acid was converted to the dimethyl ester for purification.

Production of 1,4-benzenedicarboxylic acid:
1,4-benzenedicarboxylic acid can be formed in the laboratory by oxidizing para-diderivatives of benzene, or best by oxidizing caraway oil, a mixture of cymene and cuminol, with chromic acid.

On an industrial scale, 1,4-benzenedicarboxylic acid is produced, similar to benzoic acid, by oxidation of p-xylene by oxygen from air.
This is done using acetic acid as solvent, in the presence of a catalyst such as cobalt-manganese, using a bromide promoter.

Alternatively, 1,4-benzenedicarboxylic acid can be made via the Henkel process, which involves the rearrangement of phthalic acid to 1,4-benzenedicarboxylic acid via the corresponding potassium salts.
The 1,4-benzenedicarboxylic acid is and dimethyl terephthalate, in turn, often used as a monomer component in the production of polymers, principally polyethylene terephthalate (polyester or PET).

World production in 1970 was around 1.75 million tonnes.
By 2006, global PTA demand had substantially exceeded 30 million tonnes.

Metabolism/Metabolites of 1,4-benzenedicarboxylic acid:
A Rhodococcus species was isolated from soil by enriching for growth with dimethyl terephthalate as the sole carbon source.
The organism degraded dimethyl terephthalate by hydrolysis of ester-bonds to free 1,4-benzenedicarboxylic acid which in turn was metabolized through protocatechuate by an ortho-cleavage pathway

Biological Half-Life of 1,4-benzenedicarboxylic acid:
The concentrations of urine 1,4-benzenedicarboxylic acid in rats after single oral administration in dose of 100 mg/kg bw were determined by high pressure liquid chromatography.
The results showed that the first-order kinetics and two-compartment model were noted on the elimination of 1,4-benzenedicarboxylic acid.
The main toxicokinetic parameters were as follows: Ka = 0.51/hr, half-life ka = 0.488 hr, half-life alpha = 2.446 hr, time to peak = 2.160 hr, Ku = 0.143/hr, half-life beta = 31.551 hr, Xu(max) = 10.00 mg.

A procedure for the hydrolysis of phthalate esters and metabolites to free phthalic acid, recovery and esterification of the acid, and gas chromatographic quantification on 10% OV 25 on Gas Chroin Z all relative to an internal standard of 4-chlorophthalate was developed.
The measurement limit is 0.5 nmol of total phthalate/mL of urine, and replicates.

The assay is linear between 0.5 and 50 nmol/mL of urine, which spans of phthalate levels found thus far in human urine samples.
The procedure can also be used to detect levels of isophthalate and terephthalate simultaneously with phthalate.

Synthesis of 1,4-benzenedicarboxylic acid:

Amoco process:
In the Amoco process, which is widely adopted worldwide, 1,4-benzenedicarboxylic acid is produced by catalytic oxidation of p-xylene

The process uses a cobalt–manganese–bromide catalyst.
The bromide source can be sodium bromide, hydrogen bromide or tetrabromoethane.

Bromine functions as a regenerative source of free radicals.
Acetic acid is the solvent and compressed air serves as the oxidant.

The combination of bromine and acetic acid is highly corrosive, requiring specialized reactors, such as those lined with titanium.
A mixture of p-xylene, acetic acid, the catalyst system, and compressed air is fed to a reactor.

Mechanism:
The oxidation of p-xylene proceed by a free radical process.
Bromine radicals decompose cobalt and manganese hydroperoxides.

The resulting oxygen-based radicals abstract hydrogen from a methyl group, which have weaker C–H bonds than does the aromatic ring.
Many intermediates have been isolated.

p-xylene is converted to p-toluic acid, which is less reactive than the p-xylene owing to the influence of the electron-withdrawing carboxylic acid group.
Incomplete oxidation produces 4-carboxybenzaldehyde (4-CBA), which is often a problematic impurity.

Challenges:
Approximately 5% of the acetic acid solvent is lost by decomposition or "burning".
Product loss by decarboxylation to benzoic acid is common.

The high temperature diminishes oxygen solubility in an already oxygen-starved system.
Pure oxygen cannot be used in the traditional system due to hazards of flammable organic–O2 mixtures.

Atmospheric air can be used in 1,4-benzenedicarboxylic acid place, but once reacted needs to be purified of toxins and ozone depleters such as methylbromide before being released.
Additionally, the corrosive nature of bromides at high temperatures requires the reaction be run in expensive titanium reactors.

Alternative reaction media:
The use of carbon dioxide overcomes many of the problems with the original industrial process.
Because CO2 is a better flame inhibitor than N2, a CO2 environment allows for the use of pure oxygen directly, instead of air, with reduced flammability hazards.

The solubility of molecular oxygen in solution is also enhanced in the CO2 environment.
Because more oxygen is available to the system, supercritical carbon dioxide (Tc = 31 °C) has more complete oxidation with fewer byproducts, lower carbon monoxide production, less decarboxylation and higher purity than the commercial process.

In supercritical water medium, the oxidation can be effectively catalyzed by MnBr2 with pure O2 in a medium-high temperature.
Use of supercritical water instead of acetic acid as a solvent diminishes environmental impact and offers a cost advantage.
However, the scope of such reaction systems is limited by the even harsher conditions than the industrial process (300−400 °C, >200 bar).

Promotors and additives:
As with any large-scale process, many additives have been investigated for potential beneficial effects.
Promising results have been reported with the following.

Ketones act as promoters for formation of the active cobalt(III) catalyst.
In particular, ketones with a-methylene groups oxidize to hydroperoxides that are known to oxidize cobalt(II).

Butanone is often used.
Zirconium salts enhance the activity of Co-Mn-Br catalysts.

Selectivity is also improved.
N-Hydroxyphthalimide is a potential replacement for bromide, which is highly corrosive.

The phthalimide functions by formation of the oxyl radical.
Guanidine inhibits the oxidation of the first methyl but enhances the usually slow oxidation of the toluic acid.

Alternative routes:
1,4-benzenedicarboxylic acid can be prepared in the laboratory by oxidizing many para-disubstituted derivatives of benzene, including caraway oil or a mixture of cymene and cuminol with chromic acid.

Although not commercially significant is the so-called "Henkel process" or "Raecke process", named after the company and patent holder, respectively.
This process involves the transfer of carboxylate groups.
For example potassium benzoate disproportionates to potassium terephthalate and potassium phthalate rearranges to potassium terephthalate.

Lummus (now a subsidiary of McDermott International) has reported a route from the dinitrile, which can be obtained by ammoxidation of p-xylene.

1,4-benzenedicarboxylic acid is used as a filler in some military smoke grenades, most notably the American M83 smoke grenade and M90 vehicle-employed smoke grenade, producing a thick white smoke that acts as an obscurant in the visual and near-infrared spectrum when burned.

History of 1,4-benzenedicarboxylic acid:
1,4-benzenedicarboxylic acid was first isolated (from turpentine) by the French chemist Amédée Cailliot (1805–1884) in 1846.
1,4-benzenedicarboxylic acid became industrially important after World War II.

1,4-benzenedicarboxylic acid was produced by oxidation of p-xylene with dilute nitric acid.
Air oxidation of p-xylene gives p-toluic acid, which resists further air-oxidation.

Conversion of p-toluic acid to methyl p-toluate (CH3C6H4CO2CH3) opens the way for further oxidation to monomethyl terephthalate, which is further esterified to dimethyl terephthalate.
In 1955, Mid-Century Corporation and ICI announced the bromide-promoted oxidation of p-toluic acid to teraphthalic acid.

This innovation enabled the conversion of p-xylene to 1,4-benzenedicarboxylic acid without the need to isolate intermediates.
Amoco (as Standard Oil of Indiana) purchased the Mid-Century/ICI technology.

Reactivity Profile of 1,4-benzenedicarboxylic acid:
1,4-benzenedicarboxylic acid is a carboxylic acid.
1,4-benzenedicarboxylic acid donates hydrogen ions if a base is present to accept them.

This "neutralization" generates substantial amounts of heat and produces water plus a salt.
Insoluble in water but even "insoluble" carboxylic acids may absorb enough water from the air and dissolve sufficiently in 1,4-benzenedicarboxylic acid to corrode or dissolve iron, steel, and aluminum parts and containers.

May react with cyanide salts to generate gaseous hydrogen cyanide.
Will react with solutions of cyanides to cause the release of gaseous hydrogen cyanide.

Flammable and/or toxic gases and heat are generated by reaction with diazo compounds, dithiocarbamates, isocyanates, mercaptans, nitrides, and sulfides.
React with sulfites, nitrites, thiosulfates (to give H2S and SO3), dithionites (SO2), to generate flammable and/or toxic gases and heat.

Reaction with carbonates and bicarbonates generates a harmless gas (carbon dioxide) but still heat.
Can be oxidized by strong oxidizing agents and reduced by strong reducing agents.

These reactions generate heat.
May initiate polymerization reactions; may catalyze (increase the rate of) chemical reactions.

Preventive Measures of 1,4-benzenedicarboxylic acid:
The scientific literature for the use of contact lenses by industrial workers is inconsistent.
The benefits or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses.

However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye.
In those specific cases, contact lenses should not be worn.

In any event, the usual eye protection equipment should be worn even when contact lenses are in place.
Contaminated protective clothing should be segregated in such a manner so that there is no direct personal contact by personnel who handle, dispose, or clean the clothing.

Quality assurance to ascertain the completeness of the cleaning procedures should be implemented before the decontaminated protective clothing is returned for reuse by the workers.
Contaminated clothing should not be taken home at end of shift, but should remain at employee's place of work for cleaning.

1,4-Benzoquinone can be prepared by oxidation starting with aniline or by the oxidation of hydroquinone with bromic acid.
More recently, 1,4-Benzoquinone has been made biosynthetically from D-glucose.

Preparation
1,4-Benzoquinone is prepared industrially by oxidation of hydroquinone, which can be obtained by several routes.
One route involves oxidation of diisopropylbenzene and the Hock rearrangement.
The net reaction can be represented as follows:
C6H4(CHMe2)2 + 3 O2 → C6H4O2 + 2 OCMe2 + H2O
The reaction proceeds via the bis(hydroperoxide) and the hydroquinone.
Acetone is a coproduct.
Another major process involves the direct hydroxylation of phenol by acidic hydrogen peroxide: C6H5OH + H2O2 → C6H4(OH)2 + H2O Both hydroquinone and catechol are produced.
Subsequent oxidation of the hydroquinone gives the quinone.
1,4-Benzoquinone was originally prepared industrially by oxidation of aniline, for example by manganese dioxide.

This method is mainly practiced in PRC where environmental regulations are more relaxed.
Oxidation of hydroquinone is facile.
One such method makes use of hydrogen peroxide as the oxidizer and iodine or an iodine salt as a catalyst for the oxidation occurring in a polar solvent; e.g. isopropyl alcohol.
When heated to near its melting point, 1,4-benzoquinone sublimes, even at atmospheric pressure, allowing for an effective purification.
Impure samples are often dark-colored due to the presence of quinhydrone, a dark green 1:1 charge-transfer complex of quinone with hydroquinone.

Purification Methods
Purify p-benzoquinone in one or more of the following ways: steam distillation followed by filtration and drying (e.g. in a desiccator over CaCl2), crystallisation from pet ether (b 80-100o), benzene (with, then without, charcoal), water or 95% EtOH, sublimation under vacuum (e.g. from room temperature to liquid N2).
1,4-Benzoquinone slowly decomposes and should be stored, refrigerated, in an evacuated or sealed glass vessel in the dark.
1,4-Benzoquinone should be resublimed before use.

Health Hazard
1,4-Benzoquinone is moderately toxic viaingestion and skin contact.
1,4-Benzoquinone is a mutagen andmay cause cancer. Because of its low vaporpressure, 0.1 torr (at 25°C 77°F), the healthhazard due to inhalation of its vapor is low.
However, prolonged exposure may produceeye irritation, and its contact with the eyes can injure the cornea.
Contact with the skincan lead to irritation, ulceration, and necrosis.
The toxicity of 1,4-Benzoquinone is similarto that of hydroquinone and benzenetriol.

Repeated intraperitoneal administration of2 mg/kg/day to rats for 6 weeks produced significantdecreases in red blood cell, bone marrowcounts, and hemoglobin content.
In addition, relative changes inorgan weights and injuries to the liver, thymus,kidney, and spleen were observed.
Lauet al. (1988) investigated the correlation oftoxicity with increased glutathione substitutionin 1,4-benzoquinone.
With the exceptionof the fully substituted isomer, increased substitutionresulted in enhanced nephrotoxicity.
Although the conjugates were more stable tooxidation, the toxicity increased.

1,4-butanedioic Acid (Succinic Acid) also known as butanedionic acid or succinate, belongs to the class of organic compounds known as dicarboxylic acids and derivatives.
These are organic compounds containing exactly two carboxylic acid groups.
1,4-butanedioic Acid (Succinic Acid) exists in all living species, ranging from bacteria to plants to humans.

1,4-butanedioic Acid (Succinic Acid) appears as white crystals or shiny white odorless crystalline powder. pH of 0.1 molar solution: 2.7. Very acid taste.
1,4-butanedioic Acid (Succinic Acid) is an alpha,omega-dicarboxylic acid resulting from the formal oxidation of each of the terminal methyl groups of butane to the corresponding carboxy group.
1,4-butanedioic Acid (Succinic Acid) is an intermediate metabolite in the citric acid cycle.

1,4-butanedioic Acid (Succinic Acid) has a role as a nutraceutical, a radiation protective agent, an anti-ulcer drug, a micronutrient and a fundamental metabolite.
1,4-butanedioic Acid (Succinic Acid) is an alpha,omega-dicarboxylic acid and a C4-dicarboxylic acid.
1,4-butanedioic Acid (Succinic Acid) is a conjugate acid of a succinate(1-).

A water-soluble, colorless crystal with an acid taste that is used as a chemical intermediate, in medicine, the manufacture of lacquers, and to make perfume esters.
1,4-butanedioic Acid (Succinic Acid) is also used in foods as a sequestrant, buffer, and a neutralizing agent.


Succinate is generated in mitochondria via the tricarboxylic acid (TCA) cycle.
Succinate can exit the mitochondrial matrix and function in the cytoplasm as well as the extracellular space, changing gene expression patterns, modulating epigenetic landscape or demonstrating hormone-like signaling.
As such, succinate links cellular metabolism, especially ATP formation, to the regulation of cellular function.

Dysregulation of succinate synthesis, and therefore ATP synthesis, happens in some genetic mitochondrial diseases, such as Leigh syndrome, and Melas syndrome, and degradation can lead to pathological conditions, such as malignant transformation, inflammation and tissue injury.
1,4-butanedioic Acid (Succinic Acid) is marketed as food additive E363.
The name derives from Latin succinum, meaning amber.

PHYSICAL PROPERTIES OF 1,4-BUTANEDIOIC ACID (SUCCINIC ACID):
1,4-butanedioic Acid (Succinic Acid) is a white, odorless solid with a highly acidic taste.
In an aqueous solution, succinic acid readily ionizes to form its conjugate base, succinate (/ˈsʌksɪneɪt/).

As a diprotic acid, succinic acid undergoes two successive deprotonation reactions:
(CH2)2(CO2H)2 → (CH2)2(CO2H)(CO2)− + H+
(CH2)2(CO2H)(CO2)− → (CH2)2(CO2)22− + H+

The pKa of these processes are 4.3 and 5.6, respectively.
Both anions are colorless and can be isolated as the salts, e.g., Na(CH2)2(CO2H)(CO2) and Na2(CH2)2(CO2)2.
In living organisms, primarily succinate, not succinic acid, is found.

As a radical group it is called a succinyl (/ˈsʌksɪnəl/) group.
Like most simple mono- and dicarboxylic acids, it is not harmful but can be an irritant to skin and eyes.

COMMERCIAL PRODUCTION OF 1,4-BUTANEDIOIC ACID (SUCCINIC ACID):
Historically, 1,4-butanedioic Acid (Succinic Acid) was obtained from amber by distillation and has thus been known as spirit of amber.
Common industrial routes include hydrogenation of maleic acid, oxidation of 1,4-butanediol, and carbonylation of ethylene glycol.
Succinate is also produced from butane via maleic anhydride.

Global production is estimated at 16,000 to 30,000 tons a year, with an annual growth rate of 10%.
Genetically engineered Escherichia coli and Saccharomyces cerevisiae are proposed for the commercial production via fermentation of glucose.


CHEMICAL REACTIONS OF 1,4-BUTANEDIOIC ACID (SUCCINIC ACID)
1,4-butanedioic Acid (Succinic Acid) can be dehydrogenated to fumaric acid or be converted to diesters, such as diethylsuccinate (CH2CO2CH2CH3)2.
This diethyl ester is a substrate in the Stobbe condensation.
Dehydration of succinic acid gives succinic anhydride.

Succinate can be used to derive 1,4-butanediol, maleic anhydride, succinimide, 2-pyrrolidinone and tetrahydrofuran.

APPLICATIONS OF 1,4-BUTANEDIOIC ACID (SUCCINIC ACID):
In 2004, succinate was placed on the US Department of Energy's list of top 12 platform chemicals from biomass.

Precursor to polymers, resins, and solvents:
1,4-butanedioic Acid (Succinic Acid) is a precursor to some polyesters and a component of some alkyd resins.
1,4-Butanediol (BDO) can be synthesized using succinic acid as a precursor.
The automotive and electronics industries heavily rely on BDO to produce connectors, insulators, wheel covers, gearshift knobs and reinforcing beams.

1,4-butanedioic Acid (Succinic Acid) also serves as the bases of certain biodegradable polymers, which are of interest in tissue engineering applications.
Acylation with succinic acid is called succination.
Oversuccination occurs when more than one succinate adds to a substrate.


Food and dietary supplement:
As a food additive and dietary supplement, succinic acid is generally recognized as safe by the U.S. Food and Drug Administration.
Succinic acid is used primarily as an acidity regulator in the food and beverage industry.

1,4-butanedioic Acid (Succinic Acid) is also available as a flavoring agent, contributing a somewhat sour and astringent component to umami taste.
As an excipient in pharmaceutical products, it is also used to control acidity or as a counter ion.
Drugs involving succinate include metoprolol succinate, sumatriptan succinate, Doxylamine succinate or solifenacin succinate.

BIOSYNTHESIS OF 1,4-BUTANEDIOIC ACID (SUCCINIC ACID)
Tricarboxylic acid (TCA) cycle:
Succinate is a key intermediate in the tricarboxylic acid cycle, a primary metabolic pathway used to produce chemical energy in the presence of O2.
Succinate is generated from succinyl-CoA by the enzyme succinyl-CoA synthetase in a GTP/ATP-producing step:
Succinyl-CoA + NDP + Pi → Succinate + CoA + NTP
Catalyzed by the enzyme succinate dehydrogenase (SDH), succinate is subsequently oxidized to fumarate:
Succinate + FAD → Fumarate + FADH2

SDH also participates in the mitochondrial electron transport chain, where it is known as respiratory complex II.
This enzyme complex is a 4 subunit membrane-bound lipoprotein which couples the oxidation of succinate to the reduction of ubiquinone via the intermediate electron carriers FAD and three 2Fe-2S clusters.
Succinate thus serves as a direct electron donor to the electron transport chain, and itself is converted into fumarate


Reductive branch of the TCA cycle:
Succinate can alternatively be formed by reverse activity of SDH.
Under anaerobic conditions certain bacteria such as A. succinogenes, A. succiniciproducens and M. succiniciproducens, run the TCA cycle in reverse and convert glucose to succinate through the intermediates of oxaloacetate, malate and fumarate.

This pathway is exploited in metabolic engineering to net generate succinate for human use.
Additionally, succinic acid produced during the fermentation of sugar provides a combination of saltiness, bitterness and acidity to fermented alcohols.

Accumulation of fumarate can drive the reverse activity of SDH, thus enhancing succinate generation.
Under pathological and physiological conditions, the malate-aspartate shuttle or the purine nucleotide shuttle can increase mitochondrial fumarate, which is then readily converted to succinate.

Glyoxylate cycle:
Succinate is also a product of the glyoxylate cycle, which converts two two-carbon acetyl units into the four-carbon succinate.
The glyoxylate cycle is utilized by many bacteria, plants and fungi and allows these organisms to subsist on acetate or acetyl CoA yielding compounds.

The pathway avoids the decarboxylation steps of the TCA cycle via the enzyme isocitrate lyase which cleaves isocitrate into succinate and glyoxylate. Generated succinate is then available for either energy production or biosynthesis.

GABA shunt:
Succinate is the re-entry point for the gamma-aminobutyric acid (GABA) shunt into the TCA cycle, a closed cycle which synthesizes and recycles GABA.
The GABA shunt serves as an alternate route to convert alpha-ketoglutarate into succinate, bypassing the TCA cycle intermediate succinyl-CoA and instead producing the intermediate GABA.

Transamination and subsequent decarboxylation of alpha-ketoglutarate leads to the formation of GABA.
GABA is then metabolized by GABA transaminase to succinic semialdehyde.
Finally, succinic semialdehyde is oxidized by succinic semialdehyde dehydrogenase (SSADH) to form succinate, re-entering the TCA cycle and closing the loop.

Enzymes required for the GABA shunt are expressed in neurons, glial cells, macrophages and pancreatic cells






Cellular metabolism:
Metabolic intermediate:
Succinate is produced and concentrated in the mitochondria and its primary biological function is that of a metabolic intermediate.
All metabolic pathways that are interlinked with the TCA cycle, including the metabolism of carbohydrates, amino acids, fatty acids, cholesterol, and heme, rely on the temporary formation of succinate.

The intermediate is made available for biosynthetic processes through multiple pathways, including the reductive branch of the TCA cycle or the glyoxylate cycle, which are able to drive net production of succinate.
In rodents, mitochondrial concentrations are approximately ~0.5 mM while plasma concentration are only 2–20 μM.

ROS production:
The activity of succinate dehydrogenase (SDH), which interconverts succinate into fumarate participates in mitochondrial reactive oxygen species (ROS) production by directing electron flow in the electron transport chain.
Under conditions of succinate accumulation, rapid oxidation of succinate by SDH can drive reverse electron transport (RET).
If mitochondrial respiratory complex III is unable to accommodate excess electrons supplied by succinate oxidation, it forces electrons to flow backwards along the electron transport chain.

RET at mitochondrial respiratory complex 1, the complex normally preceding SDH in the electron transport chain, leads to ROS production and creates a pro-oxidant microenvironment.

Additional biologic functions:
In addition to its metabolic roles, succinate serves as an intracellular and extracellular signaling molecule.
Extra-mitochondrial succinate alters the epigenetic landscape by inhibiting the family of 2-oxogluterate-dependent dioxygenases.

Alternative, succinate can be released into the extracellular milieu and the blood stream where it is recognized by target receptors.
In general, leakage from the mitochondria requires succinate overproduction or underconsumption and occurs due to reduced, reverse or completely absent activity of SDH or alternative changes in metabolic state.
Mutations in SDH, hypoxia or energetic misbalance are all linked to an alteration of flux through the TCA cycle and succinate accumulation.

Upon exiting the mitochondria, succinate serves as a signal of metabolic state, communicating to neighboring cells how metabolically active the originating cell population is.
As such, succinate links TCA cycle dysfunction or metabolic changes to cell-cell communication and to oxidative stress-related responses.

Transporters:
Succinate requires specific transporters to move through both the mitochondrial and plasma membrane.
Succinate exits the mitochondrial matrix and passes through the inner mitochondrial membrane via dicarboxylate transporters, primarily SLC25A10, a succinate-fumarate/malate transporter.

In the second step of mitochondrial export, succinate readily crosses the outer mitochondrial membrane through porins, nonspecific protein channels that facilitate the diffusion of molecules less than 1.5 kDa.
Transport across the plasma membrane is likely tissue specific.
A key candidate transporter is INDY (I'm not dead yet), a sodium-independent anion exchanger, which moves both dicarboxylate and citrate into the bloodstream

Extracellular signaling:
Extracellular succinate can act as a signaling molecule with hormone-like function, targeting a variety of tissues such as blood cells, adipose tissue, immune cells, the liver, the heart, the retina and primarily the kidney.
The G-protein coupled receptor, GPR91 also known as SUCNR1, serves as the detector of extracellular succinate.
Arg99, His103, Arg252, and Arg281 near the center of the receptor generate a positively charged binding site for succinate.

The ligand specificity of GPR91 was rigorously tested using 800 pharmacologically active compounds and 200 carboxylic acid and succinate-like compounds, all of which demonstrated significantly lower binding affinity.
Overall, the EC50 for succinate-GPR91 is in the 20–50 uM range.
Depending on the cell type, GPR91 can interact with multiple G proteins, including Gs, Gi and Gq, and enabling a multitude of signaling outcomes.


Effect on adipocytes:
In adipocytes, the succinate-activated GPR91 signaling cascade inhibits lipolysis.
Effect on the liver and retina
Succinate signaling often occurs in response to hypoxic conditions. In the liver, succinate serves as a paracrine signal, released by anoxic hepatocytes, and targets stellate cells via GPR91.

This leads to stellate cell activation and fibrogenesis.
Thus, succinate is thought to play a role in liver homeostasis.
In the retina, succinate accumulates in retinal ganglion cells in response to ischemic conditions.

Autocrine succinate signaling promotes retinal neovascularization, triggering the activation of angiogenic factors such as endothelial growth factor (VEGF).

Effect on the heart:
Extracellular succinate regulates cardiomyocyte viability through GPR91 activation; long-term succinate exposure leads to pathological cardiomyocyte hypertrophy.
Stimulation of GPR91 triggers at least two signaling pathways in the heart: a MEK1/2 and ERK1/2 pathway that activates hypertrophic gene expression and a phospholipase C pathway which changes the pattern of Ca2+ uptake and distribution and triggers CaM-dependent hypertrophic gene activation.


Effect on immune cells:
SUCNR1 is highly expressed on immature dendritic cells, where succinate binding stimulates chemotaxis.
Furthermore, SUCNR1 synergizes with toll-like receptors to increase the production of proinflammatory cytokines such as TNF alpha and interleukin-1beta.

Succinate may enhance adaptive immunity by triggering the activity of antigen-presenting cells that, in turn, activate T-cells.

Effect on platelets:
SUCNR1 is one of the highest expressed G protein-coupled receptors on human platelets, present at levels similar to P2Y12, though the role of succinate signaling in platelet aggregation is debated.
Multiple studies have demonstrated succinate-induced aggregation, but the effect has high inter-individual variability.

Effect on the kidneys
Succinate serves as a modulator of blood pressure by stimulating renin release in macula densa and juxtaglomerular apparatus cells via GPR91.
Therapies targeting succinate to reduce cardiovascular risk and hypertension are currently under investigation


Intracellular signaling:
Accumulated succinate inhibits dioxygenases, such as histone and DNA demethylases or prolyl hydroxylases, by competitive inhibition.
Thus, succinate modifies the epigenic landscape and regulates gene expression.
Accumulation of either fumarate or succinate reduces the activity of 2-oxoglutarate-dependent dioxygenases, including histone and DNA demethylases, prolyl hydroxylases and collagen prolyl-4-hydroxylases, through competitive inhibition.

2-oxoglutarate-dependent dioxygenases require an iron cofactor to catalyze hydroxylations, desaturations and ring closures.
Simultaneous to substrate oxidation, they convert 2-oxoglutarate, also known as alpha-ketoglutarate, into succinate and CO2. 2-oxoglutarate-dependent dioxygenases bind substrates in a sequential, ordered manner.

First, 2-oxoglutarate coordinates with an Fe(II) ion bound to a conserved 2-histidinyl–1-aspartyl/glutamyl triad of residues present in the enzymatic center.
Subsequently, the primary substrate enters the binding pocket and lastly dioxygen binds to the enzyme-substrate complex.

Oxidative decarboxylation then generates a ferryl intermediate coordinated to succinate, which serves to oxidize the bound primary substrate.
Succinate may interfere with the enzymatic process by attaching to the Fe(II) center first, prohibiting the binding of 2-oxoglutarate.
Thus, via enzymatic inhibition, increased succinate load can lead to changes in transcription factor activity and genome-wide alterations in histone and DNA methylation.


Epigenetic effects:
Succinate and fumarate inhibit the TET (ten-eleven translocation) family of 5-methylcytosine DNA modifying enzymes and the JmjC domain-containing histone lysine demethylase (KDM).

Pathologically elevated levels of succinate lead to hypermethylation, epigenetic silencing and changes in neuroendocrine differentiation, potentially driving cancer formation.

Gene regulation:
Succinate inhibition of prolyl hydroxylases (PHDs) stabilizes the transcription factor hypoxia inducible factor (HIF)1α.

PHDs hydroxylate proline in parallel to oxidatively decarboxylating 2-oxyglutarate to succinate and CO2.
In humans, three HIF prolyl 4-hydroxylases regulate the stability of HIFs.

Hydroxylation of two prolyl residues in HIF1α facilitates ubiquitin ligation, thus marking it for proteolytic destruction by the ubiquitin/proteasome pathway.

Since PHDs have an absolute requirement for molecular oxygen, this process is suppressed in hypoxia allowing HIF1α to escape destruction.
High concentrations of succinate will mimic the hypoxia state by suppressing PHDs,[37] therefore stabilizing HIF1α and inducing the transcription of HIF1-dependent genes even under normal oxygen conditions.
HIF1 is known to induce transcription of more than 60 genes, including genes involved in vascularization and angiogenesis, energy metabolism, cell survival, and tumor invasion.

Role in human health:
Inflammation:
Metabolic signaling involving succinate can be involved in inflammation via stabilization of HIF1-alpha or GPR91 signaling in innate immune cells.
Through these mechanisms, succinate accumulation has been shown to regulate production of inflammatory cytokines.
For dendritic cells, succinate functions as a chemoattractant and increases their antigen-presenting function via receptor stimulated cytokine production.

In inflammatory macrophages, succinate-induced stability of HIF1 results in increased transcription of HIF1-dependent genes, including the pro-inflammatory cytokine interleukin-1β.
Other inflammatory cytokines produced by activated macrophages such as tumor necrosis factor or interleukin 6 are not directly affected by succinate and HIF1.


The mechanism by which succinate accumulates in immune cells is not fully understood.
Activation of inflammatory macrophages through toll-like receptors induces a metabolic shift towards glycolysis.
In spite of a general downregulation of the TCA cycle under these conditions, succinate concentration is increased.
However, lipopolysaccharides involved in the activation of macrophages increase glutamine and GABA transporters.

Succinate may thus be produced from enhanced glutamine metabolism via alpha-ketoglutarate or the GABA shunt.

Tumorigenesis:
Succinate is one of three oncometabolites, metabolic intermediates whose accumulation causes metabolic and non-metabolic dysregulation implicated in tumorigenesis.
Loss-of-function mutations in the genes encoding succinate dehydrogenase, frequently found in hereditary paraganglioma and pheochromocytoma, cause pathological increase in succinate.

SDH mutations have also been identified in gastrointestinal stromal tumors, renal tumors, thyroid tumors, testicular seminomas and neuroblastomas.
The oncogenic mechanism caused by mutated SHD is thought to relate to succinate's ability to inhibit 2-oxogluterate-dependent dioxygenases. Inhibition of KDMs and TET hydroxylases results in epigenetic dysregulation and hypermethylation affecting genes involved in cell differentiation.

Additionally, succinate-promoted activation of HIF-1α generates a pseudo-hypoxic state that can promote tumorneogensis by transcriptional activation of genes involved in proliferation, metabolism and angiogenesis.
The other two oncometabolites, fumarate and 2-hydroxyglutarate have similar structures to succinate and function through parallel HIF-inducing oncogenic mechanisms.

Ischemia reperfusion injury:
Succinate accumulation under hypoxic conditions has been implicated in the reperfusion injury through increased ROS production.

During ischemia, succinate accumulates.
Upon reperfusion, succinate is rapidly oxidized leading to abrupt and extensive production of ROS.
ROS then trigger the cellular apoptotic machinery or induce oxidative damage to proteins, membranes, organelles etc.

In animal models, pharmacological inhibition of ischemic succinate accumulation ameliorated ischemia-reperfusion injury.
As of 2016 the inhibition of succinate-mediated ROS production was under investigation as a therapeutic drug target.

1,4-BUTANEDIOL
1,4-Butanediol Synthesis of 1,4-Butanediol In its industrial synthesis, acetylene reacts with two equivalents of formaldehyde to form 1,4-butynediol. This type of acetylene-based process is illustrative of what is known as "Reppe chemistry", after German chemist Walter Reppe. Hydrogenation of 1,4-butynediol gives 1,4-butanediol. It is also manufactured on an industrial scale from maleic anhydride in the Davy process, which is first converted to the methyl maleate ester, then hydrogenated. Other routes are from butadiene, allyl acetate and succinic acid. A biological route to BD has been commercialized that uses a genetically modified organism. The biosynthesis proceeds via 4-hydroxybutyrate. Industrial use of 1,4-Butanediol 1,4-Butanediol is used industrially as a solvent and in the manufacture of some types of plastics, elastic fibers and polyurethanes. In organic chemistry, 1,4-butanediol is used for the synthesis of γ-butyrolactone (GBL). In the presence of phosphoric acid and high temperature, it dehydrates to the important solvent tetrahydrofuran. At about 200 °C in the presence of soluble ruthenium catalysts, the diol undergoes dehydrogenation to form butyrolactone. Almost half of it is dehydrated to tetrahydrofuran to make fibers such as Spandex. Toxicity of 1,4-Butanediol When mixed with other drugs, misuse of 1,4-butanediol has resulted in addiction and death. Use as a recreational drug FDA warning against products containing GHB and its prodrugs, such as 1,4-butanediol. 1,4-Butanediol is also used as a recreational drug known by some users as "One Comma Four", "Liquid Fantasy", "One Four Bee" or "One Four B-D-O". It exerts effects similar to γ-hydroxybutyrate (GHB), which is a metabolic product of 1,4-butanediol. Pharmacokinetics 1,4-Butanediol is converted into GHB by the enzymes alcohol dehydrogenase and aldehyde dehydrogenase, and differing levels of these enzymes may account for differences in effects and side effects between users. While co-administration of ethanol and GHB already poses serious risks, co-administration of ethanol with 1,4-butanediol will interact considerably and has many other potential risks. This is because the same enzymes that are responsible for metabolizing alcohol also metabolize 1,4-butanediol so there is a strong chance of a dangerous drug interaction. Emergency room patients who overdose on both ethanol and 1,4-butanediol often present with symptoms of alcohol intoxication initially and as the ethanol is metabolized the 1,4-butanediol is then able to better compete for the enzyme and a second period of intoxication ensues as the 1,4-butanediol is converted into GHB. Pharmacodynamics 1,4-Butanediol seems to have two types of pharmacological actions. The major psychoactive effects of 1,4-butanediol are because it is metabolized into GHB; however there is a study suggesting that 1,4-butanediol may have potential alcohol-like pharmacological effects on its own. The study arrived at this conclusion based on the finding that 1,4-butanediol co-administered with ethanol led to potentiation of some of the behavioral effects of ethanol. However, potentiation of ethanol's effects may simply be caused by competition for the alcohol dehydrogenase and aldehyde dehydrogenase enzymes with co-administered 1,4-butanediol. The shared metabolic rate-limiting steps thus leads to slowed metabolism and clearance for both compounds including ethanol's known toxic metabolite acetaldehyde. Another study found no effect following intracerebroventricular injection in rats of 1,4-butanediol. This contradicts the hypothesis of 1,4-butanediol having inherent alcohol-like pharmacological effects. Like GHB, 1,4-butanediol is only safe in small amounts. Adverse effects in higher doses include nausea, vomiting, dizziness, sedation, vertigo, and potentially death if ingested in large amounts. Anxiolytic effects are diminished and side effects increased when used in combination with alcohol. Legality of 1,4-Butanediol While 1,4-butanediol is not currently scheduled federally in the United States, a number of states have classified 1,4-butanediol as a controlled substance. Individuals have been prosecuted for 1,4-butanediol under the Federal Analog Act as substantially similar to GHB. A federal case in New York in 2002 ruled that 1,4-butanediol could not be considered an analog of GHB under federal law, but that decision was later overturned by the Second Circuit. However, a jury in Federal District Court in Chicago found that 1,4-butanediol was not be an analog of GHB under federal law, and the Seventh Circuit Court of Appeals upheld that verdict. In the United Kingdom, 1,4-butanediol was scheduled in December 2009 (along with another GHB precursor, gamma-butyrolactone) as a Class C controlled substance. In Germany, the drug is not explicitly illegal, but might also be treated as illegal if used as a drug. It is controlled as a Schedule VI precursor in Canada. 2007 contamination of Bindeez toy A toy called "Bindeez" ("Aqua Dots" in North America) was recalled by the distributor in November 2007 because of the presence of 1,4-butanediol. The toy consists of small beads that stick to each other by sprinkling water. 1,4-Butanediol was detected by GC-MS. The production plant seems to have intended to cut costs by replacing less toxic 1,5-pentanediol with 1,4-butanediol. Properties of 1,4-Butanediol Chemical formula C4H10O2 Molar mass 90.122 g·mol−1 Density 1.0171 g/cm3 (20 °C) Melting point 20.1 °C (68.2 °F; 293.2 K) Boiling point 235 °C (455 °F; 508 K) Solubility in water Miscible Solubility in ethanol Soluble Magnetic susceptibility (χ) -61.5·10−6 cm3/mol Refractive index (nD) 1.4460 (20 °C) 1,4-Butanediol is completely metabolized in rabbits. No free 1,4-butanediol could be detected in the urine after oral administration of 4 mmol 1,4-butanediol/kg bw (equivalent to 361 mg/kg). About 1% of the administered dose was found to be conjugated with glucuronic acid, while 7% was excreted as succinic acid. 1,4-Butanediol was rapidly metabolized to 4-hydroxybutyric acid in humans and monkeys. The appearance of 4-hydroxybutyric acid as a metabolite was faster in man than in monkey. This chemical appeared to have two types of pharmacologic actions, one attributable to its conversion to gamma-hydroxybutyric acid and the other an inherent property of the diol itself. It is generally accepted that gamma-hydroxybutyric acid crosses the blood-brain barrier and shows neuropharmacologic responses same as 1,4-butanediol. Therefore, neurotoxic effect of 1,4-butanediol is considered to be caused by the metabolite, gamma-hydroxybutyric acid. Recently, a metabolism and disposition study conducted in F344/N rats by the NTP confirmed the rapid and extensive conversion of 1-(14C)-1,4-butanediol to 14CO2. Based on this information, it is considered that 1,4-butanediol is rapidly absorbed and metabolized to gamma-hydroxybutyric acid in animals as well as humans. Here we show that in vivo injection of 1,4-butanediol into adult Drosophila leads to GHB synthesis (GHB was detectable 5 min after 1,4-butanediol injection and increased dramatically 1-2 hr later). This synthesis of GHB was accompanied by an impairment of locomotor activity that was mimicked by a direct injection of GHB into flies. We propose Drosophila as a model to study the molecular actions of 1,4-butanediol and GHB. 1,4-Butanediol is a gamma hydroxybutryic acid (GHB) analogue that can be used as a substitute for GHB. When ingested, 1,4-butanediol is metabolized to GHB and produces similar effects. IDENTIFICATION of 1,4-Butanediol: 1,4-Butanediol is a colorless, oily liquid with almost no odor. It mixes easily with water. USE: 1,4-Butanediol is used as a solvent and in the manufacturing of plastics and pharmaceuticals. It is used in personal care products and is an illicit drug in place of gamma-hydroxybutyric acid (GHB). EXPOSURE of 1,4-Butanediol: Workers that produce or use 1,4-butanediol may breathe in mists or have direct skin contact. The general population may be exposed dermally to consumer products or via its use as an illicit drug. If 1,4-butanediol is released to the environment, it will be broken down in air by reaction with hydroxyl radicals. It will not be broken down in the air by sunlight. It will not volatilize into air from soil and water surfaces. It is expected to move easily through soil. It will be broken down by microorganisms rapidly, and is not expected to build up in fish. RISK: 1,4-Butanediol is a sedative when ingested or administered intravenously, and can cause feelings of intoxication. Additional effects associated with sedative doses include restlessness, muscle spasms, shortness of breath, low respiratory rate, vomiting, seizures, unconsciousness, coma and even death. 1,4-Butanediol is addictive, so people who use it recreationally may experience symptoms of withdrawal. No evidence of infertility, abortion or birth defects were observed in laboratory animals following oral exposure to 1,4-butanediol before and/or during pregnancy. Decreased birth weights were observed in offspring at high doses that also caused maternal toxicity (decreased weight gain, mild kidney and liver effects, and death in some animals). Data on the potential for 1,4-butanediol to cause cancer in laboratory animals were not available. However, there is evidence that its main breakdown product (GHB) causes cancer in laboratory animals exposed over time, suggesting a low potential for 1,4-butanediol to cause cancer in laboratory animals. The potential for 1,4-butanediol to cause cancer in humans has not been assessed by the U.S. EPA IRIS program, the International Agency for Research on Cancer, or the U.S. National Toxicology Program 14th Report on Carcinogen. 1,4-Butanediol is a versatile intermediate for the chemical industry. The most important area of application is the production of polyurethanes and poly(butylene terephthalate). Among the polyurethanes produced from 1,4-butanediol, cellular and compact elastomers are of prime importance. 1,4-Butanediol is made on a large industrial scale by continuous hydrogenation of the 2-butyne-1,4-diol over modified nickel catalysts. The one-stage flow process is carried out at 80 - 160 °C and 300 bar. An aqueous solution of 2-butyne-1,4-diol (30 - 50%), together with carbon monoxide-free hydrogen and recycled reaction mixture, which acts as medium for dissipation of heat, is lead over a reduced nickel - copper - manganese catalysts on silica gel strands. The initial temperature in the reactor is 80 °C; the temperature must not exceed 170 °C. In order to obtain a better distribution of the liquid, hydrogen is also circulated. The raw product contains methanol, propanol, and butanol as byproducts as well as traces of 2-methyl-1,4-butanediol, hydroxybutyraldehyde, acetals, and triols. The reactor effluent is worked up to pure 1,4-butanediol by fractional distillation. Mitsubishi uses a three-step process: the catalytic reaction of butadiene and acetic acid yields 1,4-diacetoxy-2-butene; subsequent hydrogenation gives 1,4-diacetoxybutane; and hydrolysis leads to 1,4-butanediol. According to a process practiced by Toyo Soda chlorine first adds to butadiene to form a mixture of 1,4-dichloro-2-butene and 3,4-dichloro-1- butene. This mixture reacts with sodium acetate to form 1,4-diacetoxy-2- butene, which is subsequently hydrogenated directly to 1,4-butanediol. 1,4-Butanediol can be stored indefinitely. The product is noncorrosive and therefore can be transported in cast iron containers. When it is stored for longer periods, storage tanks of steel or aluminum are necessary in order to avoid traces of iron in the product. In this case, a cover of dry nitrogen also is recommended. 1,4-Butanediol is an indirect food additive for use only as a component of adhesives. From June 1999 through December 1999, cases of toxic effects of 1,4-butanediol involving patients who presented to emergency departments with a clinical syndrome suggesting toxic effects of gamma-hydroxybutyrate and a history of ingesting 1,4-butanediol and patients discovered through public health officials and family members /were identified/. Gas chromatography-mass spectrometry /was used/ to measure 1,4-butanediol or its metabolite, gamma-hydroxybutyrate, in urine, serum, or blood. Nine episodes of toxic effects in eight patients who had ingested 1,4-butanediol recreationally, to enhance bodybuilding, or to treat depression or insomnia /were identified/. One patient presented twice with toxic effects and had withdrawal symptoms after her second presentation. Clinical findings and adverse events included vomiting, urinary and fecal incontinence, agitation, combativeness, a labile level of consciousness, respiratory depression, and death. No additional intoxicants were identified in six patients, including the two who died. The doses of 1,4-butanediol ingested ranged from 5.4 to 20 g in the patients who died and ranged from 1 to 14 g in the nonfatal cases. The health risks of 1,4-butanediol are similar to those of its counterparts, gamma-hydroxybutyrate and gamma-butyrolactone. These include acute toxic effects, which may be fatal, and addiction and withdrawal. IDENTIFICATION AND USE of 1,4-Butanediol: 1,4-Butanediol is a colorless, oily liquid. It is used as an industrial solvent, intermediate in organic synthesis, and polymer feedstock. Two studies have been identified concerning the experimental use of 1,4-butanediol as a sedative. HUMAN STUDIES of 1,4-Butanediol: It was reported that sleep is induced by intravenous administration or by infusion. Undesirable side-effects which may occur include restlessness and clonic spasms of the muscle of the extremities. Cases of abuse and fatal intoxication have been reported. ANIMAL STUDIES of 1,4-Butanediol: Gauze patches with undiluted 1,4-butanediol were applied to the intact and abraded skin of rabbits with occlusive dressing for 24 hours. After 1, 24, 48 and 72 hours, no reaction was observed on the intact and abraded skin. The main signs of toxicity seen in mice and rats were accelerated breathing, dyspnea, spasmodic breathing, bradycardia, exsiccosis, exophthalmus, apathy, hyperreflexia, hyporeflexia, areflexia, ataxia, atonia, twitching, reduced motility, analgesia, lying on the side, loss of righting reflexes, sedation, narcosis, hair loss and ruffled fur. Death occurred within 24 hours. Respiratory failure was thought to be the cause of death. Signs of intoxication appeared more quickly after rectal than after oral administration. In rat developmental studies, administration was conducted by gavage at doses of 200, 400 or 800 mg/kg/day from 14 days before mating to 14 days after mating in males and from 14 days before mating to day 3 of lactation in females. The parental animals exhibited no alteration in reproductive parameters including the copulation index, fertility index, gestation length, numbers of corpora lutea or implantation, implantation index, gestation index, delivery index, and behavior at delivery and lactation. Although neither the pup viability nor the incidence of morphological abnormalities was changed by administration of the compound, pup body weight was slightly but significantly decreased in the 800 mg/kg group. In a gene mutation assay using CHO cells, 1,4-butanediol did not induce any reproducible statistically or biologically significant increase in the mutant frequency of the HPRT (hypoxanthine-guanine phosphoribosyl transferase) locus with and without metabolic activation. A gene reverse mutation test was negative in S. typhimurium TA 100, TA 98, TA 1535, TA 1537 and E.coli WP2 uvrA with and without metabolic activation. ECOTOXICITY STUDIES of 1,4-Butanediol: Toxicity of this chemical to aquatic organisms seems to be low, because all toxicity data obtained were higher than 85 mg/L or 1000 mg/L which were the maximum concentrations of exposure. No fish died, and no toxic symptoms were observed in fish exposed to 92.5 mg/L of this chemical throughout 14 day test period. Also, any reproduction impairment was not observed in D. magna exposed to 85 mg/L. Ingestion of plastic toys is common in children and usually does not result in harm. We report a case of coma in a 20-month-old child after an ingestion of a toy containing 1,4-butanediol, an industrial solvent used to manufacture plastics. When ingested, 1,4-butanediol is metabolized to gamma-hydroxybutyrate, which can have significant systemic effects including death. Health care providers should suspect the possibility of a toxic component when a presumed nontoxic object causes unusual symptoms. Acute Exposure/ 1,4-Butanediol was administered to the right conjunctival sac of rabbits as a single dose of 0.1 mL. Slight reddening of the conjunctiva and small amounts of discharge were observed in all four rabbits 1 hour after ocular application. The changes diminished after 24 and 48 hours and no abnormalities were observed thereafter. In another study, there was also very slight conjunctival irritation but no corneal injury. ... Ineffective concentration of 1,4-butanediol with respect of ocular mucosa was determined 500 mg/L. 1,4-Butanediol's production and use as a solvent and chemical intermediate may result in its release to the environment through various waste streams. If released to air, a vapor pressure of 0.0105 mm Hg at 25 °C indicates 1,4-butanediol will exist solely as a vapor in the atmosphere. Vapor-phase 1,4-butanediol will be degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals; the half-life for this reaction in air is estimated to be 10 hours. 1,4-Butanediol does not contain chromophores that absorb at wavelengths >290 nm and, therefore, is not expected to be susceptible to direct photolysis by sunlight. If released to soil, 1,4-butanediol is expected to have very high mobility based upon an estimated Koc of 1. Volatilization from moist soil surfaces is not expected to be an important fate process based upon an estimated Henry's Law constant of 1.2X10-9 atm-cu m/mole. 1,4-Butanediol is not expected to volatilize from dry soil surfaces based upon its vapor pressure. Utilizing the Japanese MITI test, 83% of the Theoretical BOD was reached in 2 weeks indicating that biodegradation is an important environmental fate process in soil and water. If released into water, 1,4-butanediol is not expected to adsorb to suspended solids and sediment based upon the estimated Koc. Volatilization from water surfaces is not expected to be an important fate process based upon this compound's estimated Henry's Law constant. An estimated BCF of 3 suggests the potential for bioconcentration in aquatic organisms is low. Hydrolysis is not expected to be an important environmental fate process since this compound lacks functional groups that hydrolyze under environmental conditions (pH 5 to 9). Occupational exposure to 1,4-butanediol may occur through inhalation and dermal contact with this compound at workplaces where 1,4-butanediol is produced or used. Monitoring data indicate that the general population may be exposed to 1,4-butanediol via dermal contact with personal care products and inhalation of cigarette smoke condensate. Limited general exposure may occur with its use as an illicit drug. 1,4-Butanediol's production and use as a solvent, humectant, cross-linking agent in polyurethane elastomers, and an intermediate for plasticizers, and in the manufacture of pharmaceuticals, tetrahydrofuran, and terephthalate plastics may result in its release to the environment through various waste streams. According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere, 1,4-butanediol, which has a vapor pressure of 0.0105 mm Hg at 25 °C, is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase 1,4-butanediol is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals; the half-life for this reaction in air is estimated to be 10 hours, calculated from its rate constant of 3.67X10-11 cu cm/molecule-sec. 1,4-Butanediol does not contain chromophores that absorb at wavelengths >290 nm and, therefore, is not expected to be susceptible to direct photolysis by sunlight. The rate constant for the vapor-phase reaction of 1,4-butanediol with photochemically-produced hydroxyl radicals has been reported as 3.67X10-11 cu cm/molecule-sec at 25 °C. This corresponds to an atmospheric half-life of about 10 hours at an atmospheric concentration of 5X10+5 hydroxyl radicals per cu cm. 1,4-Butanediol is not expected to undergo hydrolysis in the environment due to the lack of functional groups that hydrolyze under environmental conditions. 1,4-Butanediol does not contain chromophores that absorb at wavelengths >290 nm and, therefore, is not expected to be susceptible to direct photolysis by sunlight. NIOSH (NOES Survey 1981-1983) has statistically estimated that 16,811 workers (3870 of these are female) were potentially exposed to 1,4-butanediol in the US. Occupational exposure to 1,4-butanediol may occur through inhalation and dermal contact with this compound at workplaces where 1,4-butanediol is produced or used. Monitoring data indicate that the general population may be exposed to 1,4-butanediol via dermal contact with personal care products and inhalation of cigarette smoke condensate. Limited exposure may occur with its use as an illicit drug. 1,4-Butanediol is a chemical. 1,4-Butanediol is used industrially to make floor stripper, paint thinner, and other solvent products. It is sometimes used in supplements as a substitute for illegal substances such as gamma butyrolactone (GBL) and gamma hydroxybutyrate (GHB). Unfortunately, butanediol is just as dangerous as GBL and GHB. 1,4-Butanediol is used for muscle strength, obesity, insomnia, and to increase the production of growth hormone, but there is no good scientific evidence to support any use. How does 1,4-Butanediol work ? 1,4-Butanediol is converted to gamma hydroxybutyrate (GHB) in the body. GHB slows down the brain, which can cause loss of consciousness along with dangerous slowing of breathing and other vital functions. It also stimulates growth hormone secretion.

1,5-pentanedioate (Pentanedioic Acid) is a linear dicarboxylic acid.
1,5-pentanedioate has been prepared by oxidizing cyclopentane, cyclopentanol and cyclopentanone.

1,5-pentanedioate is a pentanedioic acid.
On exposure to X-rays, 1,5-pentanedioate crystals generate two stable free radicals.

These free radicals have been investigated by electron nuclear double resonance (ENDOR) technique.
Presence of 1,5-pentanedioate in urine and plasma is an indicator of type I 1,5-pentanedioateuria (GA-I).

1,5-pentanedioate is formed as an intermediate during the catabolism of lysine in mammals.
Electron spin resonance spectra of radical (CO2H)CH2CH2CH(CO2H formed in 1,5-pentanedioate crystal after γ-irradiation is reported to remains trapped in 1,5-pentanedioate.
Polymorphism of Glycine-1,5-pentanedioate co-crystals has been studied by single crystal X-ray diffraction and Raman spectroscopy.

1,5-pentanedioate is a simple five-carbon linear dicarboxylic acid.
1,5-pentanedioate is naturally produced in the body during the metabolism of some amino acids, including lysine and tryptophan.

1,5-pentanedioate may cause irritation to the skin and eyes.
When present in sufficiently high levels, 1,5-pentanedioate can act as an acidogen and a metabotoxin.

An acidogen is an acidic compound that induces acidosis, which has multiple adverse effects on many organ systems.
A metabotoxin is an endogenously produced metabolite that causes adverse health effects at chronically high levels.

Chronically high levels of 1,5-pentanedioate are associated with at least three inborn errors of metabolism, including 1,5-pentanedioateuria type I, malonyl-CoA decarboxylase deficiency, and 1,5-pentanedioateuria type III.
1,5-pentanedioateuria type I (1,5-pentanedioateemia type I, glutaryl-CoA dehydrogenase deficiency, GA1, or GAT1) is an inherited disorder in which the body is unable to completely break down the amino acids lysine, hydroxylysine, and tryptophan due to a deficiency of mitochondrial glutaryl-CoA dehydrogenase (EC 1.3.99.7, GCDH).

Excessive levels of their intermediate breakdown products (e.g. 1,5-pentanedioate, glutaryl-CoA, 3-hydroxy1,5-pentanedioate, glutaconic acid) can accumulate and cause damage to the brain (and also other organs).
Babies with 1,5-pentanedioateemia type I are often born with unusually large heads (macrocephaly).

Macrocephaly is amongst the earliest signs of GA1.
GA1 also causes secondary carnitine deficiency because 1,5-pentanedioate, like other organic acids, is detoxified by carnitine.

Abnormally high levels of organic acids in the blood (organic acidemia), urine (organic aciduria), the brain, and other tissues lead to general metabolic acidosis.
Acidosis typically occurs when arterial pH falls below 7.35.

In infants with acidosis, the initial symptoms include poor feeding, vomiting, loss of appetite, weak muscle tone (hypotonia), and lack of energy (lethargy).
These can progress to heart, liver, and kidney abnormalities, seizures, coma, and possibly death.

These are also the characteristic symptoms of untreated 1,5-pentanedioateuria.
Many affected children with organic acidemias experience intellectual disability or delayed development.

In adults, acidosis or acidemia is characterized by headaches, confusion, feeling tired, tremors, sleepiness, and seizures.
Treatment of 1,5-pentanedioateuria is mainly based on the restriction of lysine intake, supplementation of carnitine, and an intensification of therapy during intercurrent illnesses.

The major principle of dietary treatment is to reduce the production of 1,5-pentanedioate and 3-hydroxy1,5-pentanedioate by restriction of natural protein, in general, and of lysine, in particular.
1,5-pentanedioate has also been found in Escherichia

1,5-pentanedioate is an alpha,omega-dicarboxylic acid which has simple 5 carbon linear dicarboxylic acid (HO2C−R−CO2H).
The molecular or chemical formula of 1,5-pentanedioate is C5H8O4.

When pentanedioic acid is present in a high amount 1,5-pentanedioate acts as a metabotoxin and as an acidogen.
1,5-pentanedioate can be synthesized by the following process

The ring-opening of butyrolactone (C4H6O2) with potassium cyanide (KCN) to produce potassium carboxylate-nitrile.
1,5-pentanedioate is hydrolyzed further to diacid.

Oxidizing dihydropyran will produce 1,5-pentanedioate.
1,5-pentanedioate can also be synthesized by treating 1,3-dibromopropane with potassium or sodium cyanide to produce dinitrile.
Further, 1,5-pentanedioate is hydrolysed to obtain 1,5-pentanedioate.

1,5-pentanedioate is used as the raw material for organic synthesis, pharmaceutical intermediate and synthetic resin.
1,5-pentanedioate serves as a precursor in the production of polyester polyols, polyamides, ester plasticizers and corrosion inhibitors.

1,5-pentanedioate is useful to decrease polymer elasticity and in the synthesis surfactants and metal finishing compounds.

Their reactions with bases, called "neutralizations", are accompanied by the evolution of substantial amounts of heat.

Neutralization between an acid and a base produces water plus a salt.
Carboxylic acids with six or fewer carbon atoms are freely or moderately soluble in water; those with more than six carbons are slightly soluble in water.

Soluble carboxylic acid dissociate to an extent in water to yield hydrogen ions.
The pH of solutions of carboxylic acids is therefore less than 7.0.

Many insoluble carboxylic acids react rapidly with aqueous solutions containing a chemical base and dissolve as the neutralization generates a soluble salt.
Carboxylic acids in aqueous solution and liquid or molten carboxylic acids can react with active metals to form gaseous hydrogen and a metal salt.

Even "insoluble" carboxylic acids may absorb enough water from the air and dissolve sufficiently in 1,5-pentanedioate to corrode or dissolve iron, steel, and aluminum parts and containers.

Carboxylic acids, like other acids, react with cyanide salts to generate gaseous hydrogen cyanide.
The reaction is slower for dry, solid carboxylic acids.

Insoluble carboxylic acids react with solutions of cyanides to cause the release of gaseous hydrogen cyanide.
Flammable and/or toxic gases and heat are generated by the reaction of carboxylic acids with diazo compounds, dithiocarbamates, isocyanates, mercaptans, nitrides, and sulfides.

Carboxylic acids, especially in aqueous solution, also react with sulfites, nitrites, thiosulfates (to give H2S and SO3), dithionites (SO2), to generate flammable and/or toxic gases and heat.
Their reaction with carbonates and bicarbonates generates a harmless gas (carbon dioxide) but still heat.

Like other organic compounds, carboxylic acids can be oxidized by strong oxidizing agents and reduced by strong reducing agents.

1,5-Pentanedioic acid can be prepared by the ring-opening of butyrolactone with potassium cyanide to give the mixed potassium carboxylate-nitrile that is hydrolyzed to the diacid.
Alternatively hydrolysis, followed by oxidation of dihydropyran gives 1,5-Pentanedioic acid.
1,5-Pentanedioic acid can also be prepared from reacting 1,3-dibromopropane with sodium or potassium cyanide to obtain the dinitrile, followed by hydrolysis.
1,5-Pentanedioic acid itself has been used in the production of polymers such as polyester polyols, polyamides.

As 1,6-Hexamethyleneglycol contains the hydroxyl group, it undergoes the typical chemical reactions of alcohols such as dehydration, substitution, esterification.
Dehydration of 1,6-Hexamethyleneglycol gives oxepane, 2-methyltetrahydropyran and 2-ethyltetrahydrofuran.
Corresponding thiophene and pyrrolidone can be made by reacting 1,6-Hexamethyleneglycol with hydrogen sulfide and ammonia respectively.

Uses
1,6-Hexamethyleneglycol can improve the hardness and flexibility of polyesters as it contains a fairly long hydrocarbon chain.
In polyurethanes, 1,6-Hexamethyleneglycol is used as a chain extender, and the resulting modified polyurethane has high resistance to hydrolysis as well as mechanical strength, but with a low glass transition temperature.
1,6-Hexamethyleneglycol is also an intermediate to acrylics as a crosslinking agent, e.g. hexanediol diacrylate.
Unsaturated polyester resins have also been made from 1,6-Hexamethyleneglycol, along with styrene, maleic anhydride and fumaric acid.

Uses to study biomolecular condensates
1,6-Hexamethyleneglycol has been used to characterize biomolecular condensates.
The material properties of condensates can be examined to determine if they are solid or liquid condensates.
1,6-Hexamethyleneglycol has been reported to interfere with weak hydrophobic protein-protein or protein-RNA interactions that comprise liquid condensates.
1,6-Hexamethyleneglycol has been reported to dissolve liquid but not solid condensates.
2,5 hexanediol or 1,4-butanediol has been observed to have minimal effect on behavior of disorderd proteins as compared to 1,6-Hexamethyleneglycol.

Production
1,6-Hexamethyleneglycol is prepared by the hydrogenation of adipic acid or its esters.
Laboratory preparation could be achieved by reduction of adipates with lithium aluminium hydride, although this method is impractical on a commercial scale.

Production Methods
1,6-Hexamethyleneglycol is produced industrially by the catalytic hydrogenation of adipic acid or of its esters.
Mixtures of dicarboxylic acids and hydroxycarboxylic acids with C6 components formed in other processes (e.g., in cyclohexane oxidation) are also used.
Esterifification of "distillation heavies" with lower alcohols is often carried out before hydrogenation.
The acids are hydrogenated continuously at 170-240 ℃ and at 15.0-30.0 MPa on a suitable catalyst either in a trickle-flflow (downflflow) or a bubble-flflow (upflflow) fifixed-bed reactor.
The reactor temperature is controlled by circulating part of the reactor discharge.

The hydrogen required for the hydrogenation is fed together with the recycle gas through the recycle gas compressor to the reactor.
Side products of the synthesis are alcohols, ethers, diols, and esters.
Pure 1,6-Hexamethyleneglycol is obtained by fractional distillation of the crude reactor discharge.
For the hydrogenation of dicarboxylic acids, catalysts containing cobalt, copper, or manganese are suitable.
For the hydrogenation of esters, catalysts such as copper chromite or copper with added zinc and barium are used as "full catalysts" or on inert carriers.
Ruthenium, platinum, or palladium on inert supports can also be used.
Gas-phase hydrogenation of esters of adipic or 6-hydroxyhexanoic acid can be carried out at 1-7 MPa.
Both acids and esters also may be hydrogenated using suspended catalysts.
Oligomeric esters of the product diol and adipic acid can also be hydrogenated.

SHORT SUMMARY WHICH SUPPORTS THE REASONS FOR THE CONCLUSIONS AND RECOMMENDATIONS. The production volume of this chemical in Germany was 10,000-50,000t in 1991. The total production volume is used as an intermediate in chemical industry for the synthesis of polyesters and polyesterol-type polyurethanes, which are used for paints, laquers and varnishes.

GENERAL DESCRIPTION: Diols contribute to high water solubility, hygroscopicity and reactivity with many organic compounds, on usually linear and aliphatic carbon chain. 1,6-Hexanediol, linear diol containing two primary hydroxyl groups at terminal locations for reaction of di-substitution, is used as an intermediate in polymer syntheses (nylon, polyesters manufacturing). The main application field is polyurethanes manufacturing. It is also used in gasoline refining and in pharmaceutical manufacturing. Alcohols are very weak acids as they lose H+ in the hydroxyl group. Alcohols undergoes dehydration reaction which means the elimination of water molecule replaced by a pi bond between two adjacent carbon atoms to form alkenes under heating in the presence of strong acids like hydrocloric acid or phosphoric acid. Primary and secondary alcohols can be oxidized to aldehydes and ketones respectively. Carboxylic acids are obtained from oxidation of aldehydes. Oxidation in organic chemistry can be considered to be the loss of hydrogen or gain of oxygen and reduction to gain hydrogen or loss of oxygen. Tertiary alcohols do not react to give oxidation products as they have no H attached to the alcohol carbon. Alcohols undergoes important reactions called nucleophilic substitution in which an electron donor replaces a leaving group, generally conjugate bases of strong acids, as a covalent substitute of some atom. One of important reaction of alcohol is condensation. Ethers are formed by the condensation of two alcohols by heating with sulfuric acid; the reaction is one of dehydration. Almost infinite esters are formed through condensation reaction called esterification between carboxylic acid and alcohol, which produces water. Alcohols are important solvents and chemical raw materials. Alcohols are intermediates for the production of target compounds, such as pharmaceuticals, veterinary medicines, plasticizers, surfactants, lubricants, ore floatation agents, pesticides, hydraulic fluids, and detergents.

1,6-Hexanediol (HDO) is an important precursor in the polymer industry. The current industrial route to produce 1,6-Hexanediol involves energy intensive and hazardous multistage (four-pot–four-step) chemical reactions using cyclohexane (CH) as the starting material, which leads to serious environmental problems. Here, we report the development of a biocatalytic cascade process for the biotransformation of CH to 1,6-Hexanediol under mild conditions in a one-pot–one-step manner. This cascade biocatalysis operates by using a microbial consortium composed of three E. coli cell modules, each containing the necessary enzymes. The cell modules with assigned functions were engineered in parallel, followed by combination to construct E. coli consortia for use in biotransformations. The engineered E. coli consortia, which contained the corresponding cell modules, efficiently converted not only CH or cyclohexanol to 1,6-Hexanediol, but also other cycloalkanes or cycloalkanols to related dihydric alcohols. In conclusion, the newly developed biocatalytic process provides a promising alternative to the current industrial process for manufacturing 1,6-Hexanediol and related dihydric alcohols.
