Etidronate, unlike other bisphosphonates, also prevents bone calcification. For this reason, other bisphosphonates, such as alendronate, are preferred when fighting osteoporosis. To prevent bone resorption without affecting too much bone calcification, etidronate must be administered only for a short time once in a while, for example for two weeks every 3 months. When given on a continuous basis, say every day, etidronate will altogether prevent bone calcification. This effect may be useful and etidronate is in fact used this way to fight heterotopic ossification. But in the long run, if used on a continuous basis, it will cause osteomalacia.Chemical Main article: Corrosion inhibitor.HEDP is used as a retardant in concrete, scale and corrosion inhibition in circulating cool water system, oil field and low-pressure boilers in fields such as electric power, chemical industry, metallurgy, fertilizer, etc. In light woven industry, HEDP is used as detergent for metal and nonmetal. In dyeing industry, HEDP is used as peroxide stabilizer and dye-fixing agent; In non-cyanide electroplating, HEDP is used as chelating agent. The dosage of 1–10 mg/L is preferred as scale inhibitor, 10–50 mg/L as corrosion inhibitor, and 1000–2000 mg/L as detergent. Usually, HEDP is also used together with polycarboxylic acid (superplasticizer), in which it acts as reducing agent.Chelating agent and antioxidant.HEDP 4NA is a chelating agent and may be added to bind or, to some extent, counter the effects of substances, such as calcium, iron or other metal ions, which may be discharged as a component of grey wastewater and could conceivably contaminate groundwater supplies. As a phosphonate it has corrosion inhibiting properties on unalloyed steel. HEDP 4NA also acts to retard rancidification and oxidation of fatty acids.HEDP and its salts are added to detergents and other cleaning agents to prevent the effects of hard water. It is also used in peroxide bleaching to prevent degradation of peroxides by transition metals.HEDP 4NA is listed as an ingredient of several cosmetic formulations where it is used for suppressing radical formation, emulsion stabiliser and viscosity control. While HEDP 4NA has not been limited from inclusion in cosmetics and does have legitimate uses, it is recommended that, as with most cosmetic products (particularly soaps), the product should be thoroughly rinsed from the skin after use.HEDP 4NA is also included among swimming pool chemicals. It is used as a stain inhibitor to prevent metal ions coming out of solution and staining the sides of swimming pools.

General Manufacturing Information of Hexa butyl distannoxane:
Tributyltin antifouling paint can be classified into three chemical groups based on the way the tributyltin is incorporated into the paint coating and subsequently released.
The first group includes paints in which the tributyltin active ingredient is mixed into the paint matrix and the tributyltin ion is released from the paint by diffusion.

These are called free association paints.
The second group has the tributyltin moiety chemically bound to the paint matrix.

These paints are called copolymer paints and under slightly alkaline conditions (such as sea water), the tributyltin ion is released by chemical hydrolysis.
Because the paint surface is softened by the loss of the tributyltin moiety, the outer layer is exposed.

A third category, tributyltin ablative paints, have characteristics of both groups.
The tributyltin active ingredient is mixed into the paint matrix, but because these are relatively soft paints, the surface ablates or sloughs off as the painted vessel moves through the water.

The use of tributyltin compounds in antifoulants are restricted because of their toxicity to aquatic organisms and EPA is cooperating in international efforts for a global phase-out.

Corneal edema induced by tributyltin) oxide:
Comeal edema induced by bis (tributyltin) oxide was studied with an electron microscope and the accumulation sites of tin were determined with an X-ray microanalyzer.
Male Wistar rats received an intramuscular injection of 0.5 ml/kg Hexa butyl distannoxane.

After time intervals of 2,4, 6, 8, 10, 12 h after injection, corneas were isolated and provided for electron microscopy.
Corneas from untreated rats served as controls.

Marked swelling of mitochondria in the corneal endothelial cells occurred at 4 h after Hexa butyl distannoxane injection.
The corneal edema appeared in the endothelial layer and the stroma at 6 h after injection.

By X-ray microanalysis, Sn peaks were obtained from swollen mitochondria in the endothelial cells.
At 12 h after Hexa butyl distannoxane injection, edematous swelling of the corneal tissue became more advanced.

These results indicated that parenterally administered Hexa butyl distannoxane accumulated in the mitochondria of corneal endothelial cells.
The direct toxic effects of Hexa butyl distannoxane on the mitochondria might cause the interference with active pump function of endothelial cells and induced the corneal edema.

First Aid of Hexa butyl distannoxane:

EYES:
First check the victim for contact lenses and remove if present.
Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center.

STRUCTURE OF HEXAFLUOROSILICIC ACID:
Hexafluorosilicic Acid has been crystallized as various hydrates.
These include (H5O2)2SiF6, the more complicated (H5O2)2SiF6·2H2O, and (H5O2)(H7O3)SiF6·4.5H2O.
In all of these salts, the octahedral hexafluorosilicate anion is hydrogen bonded to the cations.
Aqueous solutions of Hexafluorosilicic Acid are often described as H
2SiF6.



PRODUCTION AND PRINCIPAL REACTIONS OF HEXAFLUOROSILICIC ACID:
Hexafluorosilicic acid is produced commercially from fluoride-containing minerals that also contain silicates.
Specifically, apatite and fluorapatite are treated with sulfuric acid to give phosphoric acid, a precursor to several water-soluble fertilizers.
This is called the wet phosphoric acid process.

As a by-product, approximately 50 kg of Hexafluorosilicic Acid is produced per tonne of HF owing to reactions involving silica-containing mineral impurities. 
Some of the hydrogen fluoride (HF) produced during this process in turn reacts with silicon dioxide (SiO2) impurities, which are unavoidable constituents of the mineral feedstock, to give silicon tetrafluoride.

Thus formed, the silicon tetrafluoride reacts further with HF.
The net process can be described as:
6 HF + SiO2 → SiF2−6 + 2 H3O+
Hexafluorosilicic acid can also be produced by treating silicon tetrafluoride with hydrofluoric acid.



REACTIONS OF HEXAFLUOROSILICIC ACID:
In water, Hexafluorosilicic Acid readily hydrolyzes to hydrofluoric acid and various forms of amorphous and hydrated silica ("SiO2").
At the concentration usually used for water fluoridation, 99% hydrolysis occurs and the pH drops.
The rate of hydrolysis increases with pH.

At the pH of drinking water, the degree of hydrolysis is essentially 100%.
H2SiF6 + 2 H2O → 6 HF + "SiO2"
Near neutral pH, hexafluorosilicate salts hydrolyze rapidly according to this equation:
SiF2−6 + 2 H2O → 6 F− + SiO2 + 4 H+

Alkali and alkaline earth salts
Neutralization of solutions of Hexafluorosilicic Acid with alkali metal bases produces the corresponding alkali metal fluorosilicate salts:
H2SiF6 + 2 NaOH → Na2SiF6 + 2 H2O

The resulting salt Na2SiF6 is mainly used in water fluoridation.
Related ammonium and barium salts are produced similarly for other applications.
At room temperature 15-30% concentrated hexafluorosilicic acid undergoes similar reactions with chlorides, hydroxides, and carbonates of alkali and alkaline earth metals.

Sodium hexafluorosilicate for instance may be produced by treating sodium chloride (NaCl) by hexafluorosilicic acid:
2NaCl + H2SiF6 27 °C→ Na2SiF6↓ + 2 HClBaCl2 + H2SiF6 27 °C→ BaSiF6↓ + 2 HCl
Heating sodium hexafluorosilicate gives silicon tetrafluoride:[9]: 8 
Na2SiF6 >400 °C→ SiF4 + 2 NaF

There are two carboxylic acid groups in the ortho position on a cyclohexane ring , which together form an anhydride . Extraction and representation Cyclohexane-1,2-dicarboxylic acid anhydride is produced by the nuclear hydrogenation of phthalic anhydride . [4] This additional process step is one reason for the higher price compared to the aromatic phthalic anhydride. Manufacture of HH-PSA Usage Cyclohexane-1,2-dicarboxylic acid anhydride is used as a monomer in various areas of polymer chemistry . So is z. B. to mention the application as an alternative to phthalic anhydride(Hekzahidroftalik anhidrit ) . What is desired here is better weather resistance, especially against UV light , with high hardness at the same time, which can be achieved by using hexahydrophthalic anhydride(Hekzahidroftalik anhidrit ). [5] Furthermore, with the help of cyclohexane-1,2-dicarboxylic acid anhydride, binders, polyester resins , for paint applications with a significantly lower viscosity compared to those based on isophthalic acidbe generated. This results in a higher processing solids content which is of great interest in times when a lot of attention is paid to environmental protection . [5] Processing solids are understood to be the non-volatile content of a paint system. Since the volatile components are mostly organic solvents ( VOC ), their share should be kept as low as possible. In addition to reducing the absolute amount of paint required or switching to aqueous systems, increasing the processing solids is the best option here. In addition to being used as a binder in paints, cyclohexane-1,2-dicarboxylic acid anhydride can also be used as an anhydride hardener for epoxy resins . One application would be casting resin compounds which can cure at room temperature or at elevated temperatures. The higher price compared to phthalic anhydride should also be noted here.

Hexahydrophthalic Anhydride(Hekzahidroftalik anhidrit ) HexaHydroPhthalic Anhydride Chemical Structure Composition. Uses HHPA Hexahydrophthalic Anhydride(Hekzahidroftalik anhidrit ) is mainly used as an intermediate for coating resins (alkyds, polyesters), plasticizers, sealant, curing agent in adhesive, insect repellents, rust inhibitors, electronics applications. HHPA’s Hexahydrophthalic Anhydride(Hekzahidroftalik anhidrit ) low melt viscosity, as well as its high mix ratio with epoxy resins, makes it particularly suitable as hardener for epoxy resin for applications where high filler loadings are required. HHPA Hexahydrophthalic Anhydride(Hekzahidroftalik anhidrit ) is preferred over other aromatic anhydrides in casting and coating applications for his higher resistance to yellowing. HHPA Hexahydrophthalic Anhydride(Hekzahidroftalik anhidrit ) has high-temperature stability, excellent dielectric properties, and high glass transition temperatures. Description: Hexahydrophthalic Anhydride (HHPA, Hekzahidroftalik anhidrit) is a saturated dicarboxylic anhydride and will undergo most of the reactions typical of this class of compounds. It is supplied as a white low-melting solid (38°C) which is miscible with most organic solvents. In water, it hydrolyzes to hexahydrophthalic anhydride acid Hekzahidroftalik anhidrit. Application Information: Milldride HHPA Hexahydrophthalic Anhydride(Hekzahidroftalik anhidrit ) is a very effective curing agent for epoxy resins. It is also used in the preparation of alkyd and polyester resins where good color stability is important. HHPA Hexahydrophthalic Anhydride(Hekzahidroftalik anhidrit ) cured epoxies are characterized by reduced color and improved electrical and physical properties as compared to amine-cured products. The low melting point of HHPA allows it to be easily handled and blended with liquid resins. Viscosities of the HHPA-epoxy Hexahydrophthalic Anhydride(Hekzahidroftalik anhidrit ) mixtures are lower, pot life is extended in the absence of catalyst and curing reaction is less exothermic than with other hardeners. Areas of application including casting, laminating, embedding, coating, and impregnating electrical components.

Exposure levels of HHPA Hexahydrophthalic Anhydride(Hekzahidroftalik anhidrit ) in air (gas chromatography, GC) in the range of 30-270 micrograms/m3 corresponded to urinary concentrations of 0.9-2.8 mumol hexahydrophthalic anhydride acid (HHP acid Hexahydrophthalic Anhydride(Hekzahidroftalik anhidrit ) ; GC-mass spectrometry)/mmol creatinine. In the morning samples the concentrations were less than 0.04-0.3 mumol HHP Hexahydrophthalic Anhydride(Hekzahidroftalik anhidrit ) acid/mmol creatinine. In unexposed controls, the level was less than 0.1 mumol/mmol creatinine. A correlation was found between the time-weighted levels of HHPA Hexahydrophthalic Anhydride(Hekzahidroftalik anhidrit ) in air and HHP acid in the post-shift urine (rs = 0.93; P less than 0.023), indicating that the determination of HHP acid Hexahydrophthalic Anhydride(Hekzahidroftalik anhidrit ) in urine is suitable for biologic monitoring of HHPA Hexahydrophthalic Anhydride(Hekzahidroftalik anhidrit ) exposure.

HHPA hexahydrophthalic anhydride (Hekzahidroftalik anhidrit ) is harmonized classified as a strong respiratory sensitizer (Resp. Sens. 1) in the CLP regulation and no "safe" no effect level can be derived as regards to the induction of sensitization. During the elicitation phase, the substance may evoke chronic inflammation of the lungs and this can lead to serious and permanent impairment of the lungs. The induced sensitization is irreversible, and exposure of the substance may result in a considerable increased risk of elicitation of respiratory sensitization of affected persons. This may cause limitations of normal working life and could require long term medication. We support that the criteria of article 57 f) is fulfilled and that this substance is of equivalent level of concern as CMR (Cat. 1 or 2) substances. HHPA should be identified as a SVHC substance. Member State Sweden We agree with the argumentation put forward in the Annex XV dossier and therefore consider hexahydrophthalic anhydride – HHPA hexahydrophthalic anhydride (Hekzahidroftalik anhidrit ) to be a SVHC substance of equivalent level of concern according to Article 57(f). The substance is a classified respiratory sensitizer which may cause severe and irreversible health effects, which clearly affect the quality of life of affected individuals and also high costs for society. It is difficult to establish safe exposure levels for respiratory sensitizers like HHPA hexahydrophthalic anhydride (Hekzahidroftalik anhidrit ) , which is another reason for concern. Further, it is noted that this severe endpoint has not been taken into account by registrants in their chemical safety assessment in the Registration dossier. 1. Introduction of Hexahydrophthalic anhydride (Hekzahidroftalik anhidrit ) Hexahydrophthalic anhydride (Hekzahidroftalik anhidrit ), with the CAS registry number 85-42-7, is also known as 1,2-Cyclohexanedicarboxylic acid anhydride, 1,3-Isobenzofurandione, hexahydro-. It belongs to the product categories of Diels-Alder Adducts; Organics. What's more, its systematic name is Hexahydro-2-benzofuran-1,3-dione.

Place the slides, separated, in a wide mouth glass jar preferable with a PTFE lined cap.
Add a few drops of the Hexamethyldisilazane which will then vaporize in the sealed jar reacting with the surface of the slides.
Better results are obtained if this is done while keeping the jar at 70° for twelve hours, but with the cap slightly ajar.

At the end of the twelve hours, remove the slides.
Water droplets will now "bead up" on the slide surfaces.
The layer responsible for the hydrophobic behavior with we less than one nm in thickness and will also be completely invisible to the eye.

Applications in semiconductor technology:
Hexamethyldisilazane is an outstanding adhesion promoter especially in terms of improving the adhesion of photoresist to the wafer surface.
Hexamethyldisilazane is deposited on the wafer surface prior to the deposition of resist.

Applications in nanotechnology:
The preparation of non-interacting and non-touching nanoparticles is one of the biggest challenges faced by workers in this field of research.
For those interested in the controlled synthesis of non-aggregated nanoparticles with diameters between 1 and 50 nm, one can synthesize nanosize SiO2 particles from Hexamethyldisilazane as precursor and oxygen as the oxidizing agent.

Features and Benefits of Hexamethyldisilazane:
High chemicalstability and low molecular weight
Nontoxic andcost-effective reagent

Ammonia is theonly byproduct generated during silylation
Silylationreaction using HDMS is nearly neutral and does not need any precaution

Properties of Hexamethyldisilazane:

Chemical Properties:
Hexamethyldisilazane, also known as HMDS, is an important organosilicon compound, a colorless and transparent liquid.
Hexamethyldisilazane is readily hydrolyzed and gives off NH3 to produce hexamethyldisilyl ether.

In the presence of a catalyst, Hexamethyldisilazane reacts with alcohols or phenols to produce trimethylalkoxysilane or trimethylaroxysilane.
Reacts with anhydrous hydrogen chloride, releasing NH3 or NH4Cl, to produce trimethylchlorosilane.

Physical properties:
Colorless transparent and easy flowing liquid.
Boiling point 125℃, relative density 0.76 (20/4℃).
Soluble in organic solvents, Hexamethyldisilazane will be rapidly hydrolyzed in contact with air to form trimethylsilanol and hexamethyldisilyl ether.

Synthesis and Derivatives of Hexamethyldisilazane:

Bis(trimethylsilyl)amine is synthesized by treatment of trimethylsilyl chloride with ammonia:
2 (CH3)3SiCl + 3 NH3 → [(CH3)3Si]2NH + 2 NH4Cl

Ammonium nitrate together with triethylamine can be used instead.
This method is also useful for 15N isotopic enrichment of Hexamethyldisilazane.

Alkali metal bis(trimethylsilyl)amides result from the deprotonation of bis(trimethylsilyl)amine.

For example, lithium bis(trimethylsilyl)amide (LiHMDS) is prepared using n-butyllithium:
[(CH3)3Si]2NH + BuLi → [(CH3)3Si]2NLi + BuH

LiHMDS and other similar derivatives: sodium bis(trimethylsilyl)amide (NaHMDS) and potassium bis(trimethylsilyl)amide (KHMDS) are used as a non-nucleophilic bases in synthetic organic chemistry.

Handling and Storage of Hexamethyldisilazane:

Nonfire Spill Response:
ELIMINATE all ignition sources (no smoking, flares, sparks or flames) from immediate area.
All equipment used when handling Hexamethyldisilazane must be grounded.

Do not touch or walk through spilled material.
Stop leak if you can do Hexamethyldisilazane without risk.

Prevent entry into waterways, sewers, basements or confined areas.
A vapor-suppressing foam may be used to reduce vapors.

Absorb with earth, sand or other non-combustible material.
For hydrazine, absorb with DRY sand or inert absorbent (vermiculite or absorbent pads).
Use clean, non-sparking tools to collect absorbed material.

LARGE SPILL:
Dike far ahead of liquid spill for later disposal.
Water spray may reduce vapor, but may not prevent ignition in closed spaces.

First Aid Measures of Hexamethyldisilazane:
Call 911 or emergency medical service.
Ensure that medical personnel are aware of the material(s) involved and take precautions to protect themselves.

Move victim to fresh air if Hexamethyldisilazane can be done safely.
Give artificial respiration if victim is not breathing.

Do not perform mouth-to-mouth resuscitation if victim ingested or inhaled Hexamethyldisilazane; wash face and mouth before giving artificial respiration.
Use a pocket mask equipped with a one-way valve or other proper respiratory medical device.

Administer oxygen if breathing is difficult.
Remove and isolate contaminated clothing and shoes.

In case of contact with substance, immediately flush skin or eyes with running water for at least 20 minutes.
In case of burns, immediately cool affected skin for as long as possible with cold water.

Do not remove clothing if adhering to skin.
Keep victim calm and warm.
Effects of exposure (inhalation, ingestion or skin contact) to substance may be delayed.

Fire Fighting of Hexamethyldisilazane:
Some of these materials may react violently with water.

SMALL FIRE:
Dry chemical, CO2, water spray or alcohol-resistant foam.

LARGE FIRE:
Water spray, fog or alcohol-resistant foam.
If Hexamethyldisilazane can be done safely, move undamaged containers away from the area around the fire.

Dike runoff from fire control for later disposal.
Do not get water inside containers.

FIRE INVOLVING TANKS OR CAR/TRAILER LOADS:
Fight fire from maximum distance or use unmanned master stream devices or monitor nozzles.
Cool containers with flooding quantities of water until well after fire is out.

Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank.
ALWAYS stay away from tanks engulfed in fire.

Isolate spill or leak area for at least 50 meters (150 feet) in all directions.

SPILL:
Increase the immediate precautionary measure distance, in the downwind direction, as necessary.

FIRE:
If tank, rail car or tank truck is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions.
Also, consider initial evacuation for 800 meters (1/2 mile) in all directions.

Disposal Methods of Hexamethyldisilazane:
The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational exposure or environmental contamination.
Recycle any unused portion of the material for Hexamethyldisilazane approved use or return Hexamethyldisilazane to the manufacturer or supplier.

Ultimate disposal of the chemical must consider:
The material's impact on air quality; potential migration in soil or water; effects on animal, aquatic, and plant life; and conformance with environmental and public health regulations.

Preventive Measures of Hexamethyldisilazane:
The scientific literature for the use of contact lenses in industry is conflicting.
The benefit or detrimental effects of wearing contact lenses depend not only upon Hexamethyldisilazane, but also on factors including the form of Hexamethyldisilazane, 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.

APPLICATIONS


Hexamethylenediamine is used almost exclusively for the production of polymers, an application that takes advantage of its structure.
Furthermore, Hexamethylenediamine is difunctional in terms of the amine groups and tetra functional with respect to the amine hydrogens.

The great majority of the diamine is consumed by the production of nylon 66 via condensation with adipic acid.
Moreover, Hexamethylenediamine is generated from this diamine by phosgenation as a monomer feedstock in the production of polyurethane.

Hexamethylenediamine also serves as a cross-linking agent in epoxy resins.


Some uses of Hexamethylenediamine:

Materials used for construction (e.g. flooring, tile, sinks, bathtubs, mirrors, wall materials/drywall, wall-to-wall carpets, insulation, playground surfaces); includes semi-permanent fixtures such as faucets and light fixtures
Buffering
Monomer
Polymer
Construction and building materials
Intermediate
Isocyanates
Scale and corrosion inhibitors
Water treatment chemicals
Epoxy curing agents
Polyamide resins, adhesives, inks, fibers
Petroleum additives
Intermediates


Hexamethylenediamine and adipic acid are the starting materials for nylon 6,6 used widely in textiles and plastics.
Besides, Hexamethylenediamine reduce yellowing in PU resin.

Hexamethylenediamine can react with the phosgene and produce the HexamethylenDiIsocyanate (HDI).

Hexamethylenediamine is moderately toxic.
Besides, Hexamethylenediamine can cause serious burns and severe irritation.

In addition, Hexamethylenediamine can be founded as various grade.

Hexamethylenediamine is one of the largest chemical distributor in Europe.
More to that, Hexamethylenediamine is handling the storage, transport, export & import formalities of Hexamethylenediamine globally.

Hexamethylenediamine can be used as a reagent used to modify acrylonitrile copolymers and to polycondense with compounds such as calcein


Hexamethylenediamine can be used as a:

Reactant for the synthesis of dialkyl hexamethylene-1,6-dicarbamate with alkyl carbamate in the presence of various metal catalysts via the transesterification reaction
Surface modifier for chlorinated and fluorinated nanodiamond synthesized by detonation.

Hexamethylenediamine was first reported by Theodor Curtius.
Additionally, Hexamethylenediamine is produced by the hydrogenation of adiponitrile:
NC(CH2)4CN + 4 H2 → H2N(CH2)6NH2


The hydrogenation is conducted on molten adiponitrile diluted with ammonia, typical catalysts being based on cobalt and iron.
The yield is good, but commercially significant side products are generated by virtue of reactivity of partially hydrogenated intermediates.
These other products include 1,2-diaminocyclohexane, hexamethyleneimine, and the triamine bis(hexamethylenetriamine).

An alternative process uses Raney nickel as the catalyst and adiponitrile that is diluted with hexamethylenediamine itself (as the solvent).
This process operates without ammonia and at lower pressure and temperature.

Hexamethylenediamine’s primary use is for manufacturing unmodified resins, water treatment resins, resins used in paper manufacture and adhesive resins.
Other applications of Hexamethylenediamine include use as an intermediate to make polyamides with applications in fiber, plastics, polyurethane coatings and adhesives, specialty nylons (monofilaments and inks), and specialty chemicals (biocides, petroleum additives, and phenol purification).

Hexamethylenediamine is solely an industrial product, not designed for consumer use.

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 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.

DESCRIPTION:
Hexamethylenetetramine, also known as methenamine, hexamine, or its trade name Urotropin, is a heterocyclic organic compound with the formula (CH2)6N4.
Hexamethylenetetramine is highly soluble in water and polar organic solvents.
Hexamethylenetetramine has a cage-like structure similar to adamantane.

CAS Number, 100-97-0
EC Number, 202-905-8

Hexamethylenetetramine is useful in the synthesis of other organic compounds, including plastics, pharmaceuticals, and rubber additives.
Hexamethylenetetramine sublimes in vacuum at 280 °C.


Hexamethylenetetramine appears as odorless white crystalline powder or colorless lustrous crystals.
Hexamethylenetetramine Sublimes in a vacuum at about 505 °F with some decomposition.
Solutions are strong bases (pH of 0.2 molar aqueous solution is 8.4).


Hexamethylenetetramine is a polycyclic cage that is adamantane in which the carbon atoms at positions 1, 3, 5 and 7 are replaced by nitrogen atoms.
Hexamethylenetetramine has a role as an antibacterial drug.
Hexamethylenetetramine is a polycyclic cage, a polyazaalkane and a tetramine.


Hexamethylenetetramine is a heterocyclic organic compound with a cage-like structure similar to adamantane.
In salt form Hexamethylenetetramine is used for the treatment of urinary tract infection (Example: methenamine hippurate which is the hippuric acid salt of methenamine).







SYNTHESIS, STRUCTURE, REACTIVITY OF HEXAMETHYLENETETRAMINE:
Hexamethylenetetramine was discovered by Aleksandr Butlerov in 1859.
Hexamethylenetetramine is prepared industrially by combining formaldehyde and ammonia:
The reaction can be conducted in gas phase and in solution.


The molecule has a tetrahedral cage-like structure, similar to adamantane.
Four vertices are occupied by nitrogen atoms, which are linked by methylene groups.
Although the molecular shape defines a cage, no void space is available at the interior for binding other atoms or molecules, unlike crown ethers or larger cryptand structures.


The molecule behaves like an amine base, undergoing protonation and N-alkylation (e.g. quaternium-15).

APPLICATIONS OF HEXAMETHYLENETETRAMINE:
The dominant use of hexamethylenetetramine is in the production of powdery or liquid preparations of phenolic resins and phenolic resin moulding compounds, where it is added as a hardening component.
These products are used as binders, e.g. in brake and clutch linings, abrasive products, non-woven textiles, formed parts produced by moulding processes, and fireproof materials.

Industry Uses:
Hexamethylenetetramine is dominantly used in the production of powdery or liquid preparations of phenolic resins and phenolic resin molding compounds where it is added as a hardening component.
These products are used as binders in the manufacture of brake and clutch linings, abrasive products, non-woven textiles, formed parts produced by molding processes, and fireproof materials.
Hexamethylenetetramine is also used in the medical profession for the treatment of urinary tract infections.

Because Hexamethylenetetramine is smokeless when burned, has a high energy density of 30.0 megajoules per kilogram (MJ/kg), does not liquify while burning, and leaves no ashes, hexamethylenetetramine is a component of hexamine fuel tablets used by campers, hobbyists, the military and relief organizations for heating camping food as well as military rations.
The crystalline compound is also used as a reagent in organic chemistry, a food additive as a preservative, and as the base component in the manufacture of certain explosives.





MEDICAL USES OF HEXAMETHYLENETETRAMINE:
As the mandelic acid salt (methenamine mandelate) or the hippuric acid salt (methenamine hippurate), it is used for the treatment of urinary tract infection.
In an acidic environment, methenamine is believed to act as an antimicrobial by converting to formaldehyde.
A systematic review of its use for this purpose in adult women found there was insufficient evidence of benefit and further research is needed.

A UK study showed that methenamine is as effective as daily low-dose antibiotics at preventing UTIs among women who experience recurrent UTIs.
As methenamine is an antiseptic, it may avoid the issue of antibiotic resistance.
Methenamine acts as an over-the-counter antiperspirant due to the astringent property of formaldehyde.


HISTOLOGICAL STAINS OF HEXAMETHYLENETETRAMINE:
Methenamine silver stains are used for staining in histology, including the following types:
Grocott's methenamine silver stain, used widely as a screen for fungal organisms.
Jones' stain, a methenamine silver-Periodic acid-Schiff that stains for basement membrane, availing to view the "spiked" Glomerular basement membrane associated with membranous glomerulonephritis.


Solid fuel:
Together with 1,3,5-trioxane, hexamethylenetetramine is a component of hexamine fuel tablets used by campers, hobbyists, the military and relief organizations for heating camping food or military rations.
It burns smokelessly, has a high energy density of 30.0 megajoules per kilogram (MJ/kg), does not liquify while burning, and leaves no ashes, although its fumes are toxic.[citation needed]
Standardized 0.149 g tablets of methenamine (hexamine) are used by fire-protection laboratories as a clean and reproducible fire source to test the flammability of carpets and rugs.


Food additive:
Hexamethylenetetramine or hexamine is also used as a food additive as a preservative (INS number 239).
Hexamethylenetetramine is approved for usage for this purpose in the EU, where it is listed under E number E239, however it is not approved in the USA, Russia, Australia, or New Zealand.

Reagent in organic chemistry:
Hexamethylenetetramine is a versatile reagent in organic synthesis.
Hexamethylenetetramine is used in the Duff reaction (formylation of arenes), the Sommelet reaction (converting benzyl halides to aldehydes), and in the Delepine reaction (synthesis of amines from alkyl halides).


Explosives:
Hexamethylenetetramine is the base component to produce RDX and, consequently, C-4 as well as octogen (a co-product with RDX), hexamine dinitrate, hexamine diperchlorate and HMTD.


HISTORICAL USES OF HEXAMETHYLENETETRAMINE:
Hexamethylenetetramine was first introduced into the medical setting in 1895 as a urinary antiseptic.
However, it was only used in cases of acidic urine, whereas boric acid was used to treat urinary tract infections with alkaline urine.
Scientist De Eds found that there was a direct correlation between the acidity of hexamethylenetetramine's environment and the rate of its decomposition.

Therefore, its effectiveness as a drug depended greatly on the acidity of the urine rather than the amount of the drug administered.
In an alkaline environment, hexamethylenetetramine was found to be almost completely inactive.
Hexamethylenetetramine was also used as a method of treatment for soldiers exposed to phosgene in World War I.

Subsequent studies have shown that large doses of hexamethylenetetramine provide some protection if taken before phosgene exposure but none if taken afterwards.

Hexamethylenetetramine is used in the Duff reaction (formylation of arenes), the Sommelet reaction (converting benzyl halides to aldehydes), and in the Delepine reaction (synthesis of amines from alkyl halides).

Historical Uses:
Hexamethylenetetramine was first introduced into the medical setting in 1895 as a urinary antiseptic.
However, Hexamethylenetetramine was only used in cases of acidic urine, whereas boric acid was used to treat urinary tract infections with alkaline urine.
Scientist De Eds found that there was a direct correlation between the acidity of hexamethylenetetramine's environment and the rate of its decomposition.
Therefore, its effectiveness as a drug depended greatly on the acidity of the urine rather than the amount of the drug administered.
In an alkaline environment, hexamethylenetetramine was found to be almost completely inactive.
