HEALTH BENEFITS OF ACETIC ACID 80%:
1. Kills Bacteria:
Vinegar has long been used as a natural disinfectant, largely due to its content of Acetic Acid 80%.
Acetic Acid 80% has powerful antibacterial properties and can be effective at killing off several specific strains of bacteria.
In fact, one 2014 in vitro study found that Acetic Acid 80% was able to block the growth of myobacteria, a genus of bacteria responsible for causing tuberculosis and leprosy.
Other research shows that vinegar may also protect against bacterial growth, which may be partially due to the presence of Acetic Acid 80%.
2. Reduces Blood Pressure:
Not only does high blood pressure place extra strain on the heart muscle and cause it to slowly weaken over time, but high blood pressure is also a major risk factor for heart disease.
In addition to modifying your diet and exercise routine, promising research has found that Acetic Acid 80% may also help control blood pressure.
3. Decreases Inflammation:
Acute inflammation plays an important role in immune function, helping to defend the body against illness and infection.
Sustaining high levels of inflammation long-term, however, can have a detrimental effect on health, with studies showing that inflammation could contribute to the development of chronic conditions like heart disease and cancer.
Acetic Acid 80% is thought to reduce inflammation to help protect against disease.
4. Supports Weight Loss:
Some research suggests that Acetic Acid 80% could help support weight control by aiding in weight loss.
5. Promotes Blood Sugar Control:
Apple cider vinegar has been well-studied for its ability to support blood sugar control.
Research shows that Acetic Acid 80%, one of the primary components found in apple cider vinegar, may play a role in its powerful blood sugar-lowering properties.
In one study, consuming vinegar with Acetic Acid 80% alongside a high-carb meal was found to reduce blood sugar and insulin levels thanks to its ability to slow down the emptying of the stomach.
Another in vitro study had similar findings, reporting that Acetic Acid 80% decreased the activity of several enzymes involved in carbohydrate metabolism, which could decrease the absorption of carbs and sugar in the small intestine.
NOMENCLATURE OF ACETIC ACID 80%:
The trivial name "Acetic Acid 80%" is the most commonly used and preferred IUPAC name.
The systematic name "ethanoic acid", a valid IUPAC name, is constructed according to the substitutive nomenclature.
The name "Acetic Acid 80%" derives from the Latin word for vinegar, "acetum", which is related to the word "acid" itself.
"Glacial Acetic Acid 80%" is a name for water-free (anhydrous) Acetic Acid 80%.
Similar to the German name "Eisessig" ("ice vinegar"), the name comes from the solid ice-like crystals that form with agitation, slightly below room temperature at 16.6 °C (61.9 °F).
Acetic Acid 80% can never be truly water-free in an atmosphere that contains water, so the presence of 0.1% water in glacial Acetic Acid 80% lowers its melting point by 0.2 °C.
A common symbol for Acetic Acid 80% is AcOH (or HOAc), where Ac is the pseudoelement symbol representing the acetyl group CH3−C(=O)−; the conjugate base, acetate (CH3COO−), is thus represented as AcO−.
(The symbol Ac for the acetyl functional group is not to be confused with the symbol Ac for the element actinium; context prevents confusion among organic chemists).
To better reflect its structure, Acetic Acid 80% is often written as CH3−C(O)OH, CH3−C(=O)OH, CH3COOH, and CH3CO2H.
In the context of acid–base reactions, the abbreviation HAc is sometimes used, where Ac in this case is a symbol for acetate (rather than acetyl).
Acetate is the ion resulting from loss of H+ from Acetic Acid 80%.
The name "acetate" can also refer to a salt containing this anion, or an ester of Acetic Acid 80%.
HISTORY OF ACETIC ACID 80%:
Vinegar was known early in civilization as the natural result of exposure of beer and wine to air because Acetic Acid 80%-producing bacteria are present globally.
The use of Acetic Acid 80% in alchemy extends into the third century BC, when the Greek philosopher Theophrastus described how vinegar acted on metals to produce pigments useful in art, including white lead (lead carbonate) and verdigris, a green mixture of copper salts including copper(II) acetate.
Ancient Romans boiled soured wine to produce a highly sweet syrup called sapa.
Sapa that was produced in lead pots was rich in lead acetate, a sweet substance also called sugar of lead or sugar of Saturn, which contributed to lead poisoning among the Roman aristocracy.
In the 16th-century German alchemist Andreas Libavius described the production of acetone from the dry distillation of lead acetate, ketonic decarboxylation.
The presence of water in vinegar has such a profound effect on Acetic Acid 80%'s properties that for centuries chemists believed that glacial Acetic Acid 80% and the acid found in vinegar were two different substances.
French chemist Pierre Adet proved them identical.
*Crystallised Acetic Acid 80%
In 1845 German chemist Hermann Kolbe synthesised Acetic Acid 80% from inorganic compounds for the first time.
This reaction sequence consisted of chlorination of carbon disulfide to carbon tetrachloride, followed by pyrolysis to tetrachloroethylene and aqueous chlorination to trichloroAcetic Acid 80%, and concluded with electrolytic reduction to Acetic Acid 80%.
By 1910, most glacial Acetic Acid 80% was obtained from the pyroligneous liquor, a product of the distillation of wood.
The Acetic Acid 80% was isolated by treatment with milk of lime, and the resulting calcium acetate was then acidified with sulfuric acid to recover Acetic Acid 80%.
At that time, Germany was producing 10,000 tons of glacial Acetic Acid 80%, around 30% of which was used for the manufacture of indigo dye.
Because both methanol and carbon monoxide are commodity raw materials, methanol carbonylation long appeared to be attractive precursors to Acetic Acid 80%.
Henri Dreyfus at British Celanese developed a methanol carbonylation pilot plant as early as 1925.
However, a lack of practical materials that could contain the corrosive reaction mixture at the high pressures needed (200 atm or more) discouraged commercialization of these routes.
The first commercial methanol carbonylation process, which used a cobalt catalyst, was developed by German chemical company BASF in 1963.
In 1968, a rhodium-based catalyst (cis−[Rh(CO)2I2]−) was discovered that could operate efficiently at lower pressure with almost no by-products.
US chemical company Monsanto Company built the first plant using this catalyst in 1970, and rhodium-catalyzed methanol carbonylation became the dominant method of Acetic Acid 80% production (see Monsanto process).
In the late 1990s, BP Chemicals commercialised the Cativa catalyst ([Ir(CO)2I2]−), which is promoted by iridium for greater efficiency.
Known as the Cativa process, the iridium-catalyzed production of glacial Acetic Acid 80% is greener, and has largely supplanted the Monsanto process, often in the same production plants.
*Interstellar medium
Interstellar Acetic Acid 80% was discovered in 1996 by a team led by David Mehringer using the former Berkeley-Illinois-Maryland Association array at the Hat Creek Radio Observatory and the former Millimeter Array located at the Owens Valley Radio Observatory.
It was first detected in the Sagittarius B2 North molecular cloud (also known as the Sgr B2 Large Molecule Heimat source).
Acetic Acid 80% has the distinction of being the first molecule discovered in the interstellar medium using solely radio interferometers; in all previous ISM molecular discoveries made in the millimetre and centimetre wavelength regimes, single dish radio telescopes were at least partly responsible for the detections.
PHYSICAL DETAILS AND PROPERTIES OF ACETIC ACID 80%:
Acetic Acid 80%, or ethanoic acid, is a clear, colorless liquid with a pungent vinegar-like odor.

With a boiling point of 118.1, °C and a melting point of 16.6°C, Acetic Acid 80% is highly soluble in water and miscible with most organic solvents.
These physical properties make Acetic Acid 80% a versatile compound for various industrial applications.
PRODUCTION METHODS OF ACETIC ACID 80%:
Acetic Acid 80% is primarily produced through two main methods: methanol carbonylation and oxidation of acetaldehyde.
The first method, methanol carbonylation, is the most common process for large-scale Acetic Acid 80% production.
Acetic Acid 80% involves the reaction of methanol with carbon monoxide in the presence of a catalyst, typically rhodium or iodine compounds.
This catalytic reaction yields Acetic Acid 80% as the primary product.

PROPERTIES OF ACETIC ACID 80%:
-Acetic Acid 80% crystals:
*Acidity
The hydrogen centre in the carboxyl group (−COOH) in carboxylic acids such as Acetic Acid 80% can separate from the molecule by ionization:
CH3COOH ⇌ CH3CO−2 + H+
Because of this release of the proton (H+), Acetic Acid 80% has acidic character.
Acetic Acid 80% is a weak monoprotic acid.
In aqueous solution, Acetic Acid 80% has a pKa value of 4.76.
Acetic Acid 80%'s conjugate base is acetate (CH3COO−).
A 1.0 M solution (about the concentration of domestic vinegar) has a pH of 2.4, indicating that merely 0.4% of the Acetic Acid 80% molecules are dissociated.
Only in very dilute (< 10−6 M) solution, Acetic Acid 80% is >90% dissociated.
*Deprotonation equilibrium of Acetic Acid 80% in water
Cyclic dimer of Acetic Acid 80%; dashed green lines represent hydrogen bonds
STRUCTURE OF ACETIC ACID 80%:
In solid Acetic Acid 80%, the molecules form chains of individual molecules interconnected by hydrogen bonds.
In the vapour phase at 120 °C (248 °F), dimers can be detected.
Dimers also occur in the liquid phase in dilute solutions with non-hydrogen-bonding solvents, and to a certain extent in pure Acetic Acid 80%, but are disrupted by hydrogen-bonding solvents.
The dissociation enthalpy of the dimer is estimated at 65.0–66.0 kJ/mol, and the dissociation entropy at 154–157 J mol−1 K−1.
Other carboxylic acids engage in similar intermolecular hydrogen bonding interactions.
SOLVENT PROPERTIES OF ACETIC ACID 80%:
Liquid Acetic Acid 80% is a hydrophilic (polar) protic solvent, similar to ethanol and water.
With a relative static permittivity (dielectric constant) of 6.2, Acetic Acid 80% dissolves not only polar compounds such as inorganic salts and sugars, but also non-polar compounds such as oils as well as polar solutes.
Acetic Acid 80% is miscible with polar and non-polar solvents such as water, chloroform, and hexane.
With higher alkanes (starting with octane), Acetic Acid 80% is not miscible at all compositions, and solubility of Acetic Acid 80% in alkanes declines with longer n-alkanes.
The solvent and miscibility properties of Acetic Acid 80% make it a useful industrial chemical, for example, as a solvent in the production of dimethyl terephthalate.
BIOCHEMISTRY OF ACETIC ACID 80%:
At physiological pHs, Acetic Acid 80% is usually fully ionised to acetate.
The acetyl group, formally derived from Acetic Acid 80%, is fundamental to all forms of life.
Typically, Acetic Acid 80% is bound to coenzyme A by acetyl-CoA synthetase enzymes, where it is central to the metabolism of carbohydrates and fats.
Unlike longer-chain carboxylic acids (the fatty acids), Acetic Acid 80% does not occur in natural triglycerides.
Most of the aceate generated in cells for use in acetyl-CoA is synthesized directly from ethanol or pyruvate.
However, the artificial triglyceride triacetin (glycerine triacetate) is a common food additive and is found in cosmetics and topical medicines; this additive is metabolized to glycerol and Acetic Acid 80% in the body.
Acetic Acid 80% is produced and excreted by Acetic Acid 80% bacteria, notably the genus Acetobacter and Clostridium acetobutylicum.
These bacteria are found universally in foodstuffs, water, and soil, and Acetic Acid 80% is produced naturally as fruits and other foods spoil.
Acetic Acid 80% is also a component of the vaginal lubrication of humans and other primates, where it appears to serve as a mild antibacterial agent.
PRODUCTION OF ACETIC ACID 80%:
Acetic Acid 80% is produced industrially both synthetically and by bacterial fermentation.
About 75% of Acetic Acid 80% made for use in the chemical industry is made by the carbonylation of methanol, explained below.
The biological route accounts for only about 10% of world production, but Acetic Acid 80% remains important for the production of vinegar because many food purity laws require vinegar used in foods to be of biological origin.
Other processes are methyl formate isomerization, conversion of syngas to Acetic Acid 80%, and gas phase oxidation of ethylene and ethanol.
Acetic Acid 80% can be purified via fractional freezing using an ice bath.
The water and other impurities will remain liquid while the Acetic Acid 80% will precipitate out.
As of 2003–2005, total worldwide production of virgin Acetic Acid 80% was estimated at 5 Mt/a (million tonnes per year), approximately half of which was produced in the United States.
European production was approximately 1 Mt/a and declining, while Japanese production was 0.7 Mt/a.
Another 1.5 Mt were recycled each year, bringing the total world market to 6.5 Mt/a.
Since then, the global production has increased from 10.7 Mt/a in 2010 to 17.88 Mt/a in 2023.
*Methanol carbonylation:
Most Acetic Acid 80% is produced by methanol carbonylation.
In this process, methanol and carbon monoxide react to produce Acetic Acid 80% according to the equation:
The process involves iodomethane as an intermediate, and occurs in three steps.
A metal carbonyl catalyst is needed for the carbonylation (step 2).
CH3OH + HI → CH3I + H2O
CH3I + CO → CH3COI
CH3COI + H2O → CH3COOH + HI
Two related processes exist for the carbonylation of methanol: the rhodium-catalyzed Monsanto process, and the iridium-catalyzed Cativa process.
The latter process is greener and more efficient and has largely supplanted the former process.
Catalytic amounts of water are used in both processes, but the Cativa process requires less, so the water-gas shift reaction is suppressed, and fewer by-products are formed.
By altering the process conditions, acetic anhydride may also be produced in plants using rhodium catalysis.
*Acetaldehyde oxidation:
Prior to the commercialization of the Monsanto process, most Acetic Acid 80% was produced by oxidation of acetaldehyde.
This remains the second-most-important manufacturing method, although Acetic Acid 80% is usually not competitive with the carbonylation of methanol.
The acetaldehyde can be produced by hydration of acetylene.
This was the dominant technology in the early 1900s.
Light naphtha components are readily oxidized by oxygen or even air to give peroxides, which decompose to produce Acetic Acid 80% according to the chemical equation, illustrated with butane:
2 C4H10 + 5 O2 → 4 CH3CO2H + 2 H2O
Such oxidations require metal catalyst, such as the naphthenate salts of manganese, cobalt, and chromium.
The typical reaction is conducted at temperatures and pressures designed to be as hot as possible while still keeping the butane a liquid.
Typical reaction conditions are 150 °C (302 °F) and 55 atm.
Side-products may also form, including butanone, ethyl acetate, formic acid, and propionic acid.
These side-products are also commercially valuable, and the reaction conditions may be altered to produce more of them where needed.
However, the separation of Acetic Acid 80% from these by-products adds to the cost of the process.
Similar conditions and catalysts are used for butane oxidation, the oxygen in air to produce Acetic Acid 80% can oxidize acetaldehyde.
2 CH3CHO + O2 → 2 CH3CO2H
Using modern catalysts, this reaction can have an Acetic Acid 80% yield greater than 95%.
The major side-products are ethyl acetate, formic acid, and formaldehyde, all of which have lower boiling points than Acetic Acid 80% and are readily separated by distillation.
*Ethylene oxidation
Acetaldehyde may be prepared from ethylene via the Wacker process, and then oxidised as above.
In more recent times, chemical company Showa Denko, which opened an ethylene oxidation plant in Ōita, Japan, in 1997, commercialised a cheaper single-stage conversion of ethylene to Acetic Acid 80%.
The process is catalyzed by a palladium metal catalyst supported on a heteropoly acid such as silicotungstic acid.
A similar process uses the same metal catalyst on silicotungstic acid and silica:
C2H4 + O2 → CH3CO2H
It is thought to be competitive with methanol carbonylation for smaller plants (100–250 kt/a), depending on the local price of ethylene.
*Oxidative fermentation:
For most of human history, Acetic Acid 80% bacteria of the genus Acetobacter have made Acetic Acid 80%, in the form of vinegar.
Given sufficient oxygen, these bacteria can produce vinegar from a variety of alcoholic foodstuffs.
Commonly used feeds include apple cider, wine, and fermented grain, malt, rice, or potato mashes.
The overall chemical reaction facilitated by these bacteria is:
C2H5OH + O2 → CH3COOH + H2O
A dilute alcohol solution inoculated with Acetobacter and kept in a warm, airy place will become vinegar over the course of a few months.
Industrial vinegar-making methods accelerate this process by improving the supply of oxygen to the bacteria.
The first batches of vinegar produced by fermentation probably followed errors in the winemaking process.
If must is fermented at too high a temperature, acetobacter will overwhelm the yeast naturally occurring on the grapes.
As the demand for vinegar for culinary, medical, and sanitary purposes increased, vintners quickly learned to use other organic materials to produce vinegar in the hot summer months before the grapes were ripe and ready for processing into wine.
This method was slow, however, and not always successful, as the vintners did not understand the process.
One of the first modern commercial processes was the "fast method" or "German method", first practised in Germany in 1823.
In this process, fermentation takes place in a tower packed with wood shavings or charcoal.
The alcohol-containing feed is trickled into the top of the tower, and fresh air supplied from the bottom by either natural or forced convection.
The improved air supply in this process cut the time to prepare vinegar from months to weeks.
Nowadays, most vinegar is made in submerged tank culture, first described in 1949 by Otto Hromatka and Heinrich Ebner.
In this method, alcohol is fermented to vinegar in a continuously stirred tank, and oxygen is supplied by bubbling air through the solution.
Using modern applications of this method, vinegar of 15% Acetic Acid 80% can be prepared in only 24 hours in batch process, even 20% in 60-hour fed-batch process.
*Anaerobic fermentation:
Species of anaerobic bacteria, including members of the genus Clostridium or Acetobacterium, can convert sugars to Acetic Acid 80% directly without creating ethanol as an intermediate.
The overall chemical reaction conducted by these bacteria may be represented as:
C6H12O6 → 3 CH3COOH
These acetogenic bacteria produce Acetic Acid 80% from one-carbon compounds, including methanol, carbon monoxide, or a mixture of carbon dioxide and hydrogen:
2 CO2 + 4 H2 → CH3COOH + 2 H2O
This ability of Clostridium to metabolize sugars directly, or to produce Acetic Acid 80% from less costly inputs, suggests that these bacteria could produce Acetic Acid 80% more efficiently than ethanol-oxidizers like Acetobacter.
However, Clostridium bacteria are less acid-tolerant than Acetobacter.
Even the most acid-tolerant Clostridium strains can produce vinegar in concentrations of only a few per cent, compared to Acetobacter strains that can produce vinegar in concentrations up to 20%.
At present, it remains more cost-effective to produce vinegar using Acetobacter, rather than using Clostridium and concentrating it.
As a result, although acetogenic bacteria have been known since 1940, their industrial use is confined to a few niche applications.
REACTIONS OF ACETIC ACID 80%:
Acetic Acid 80% undergoes the typical chemical reactions of a carboxylic acid.
Upon treatment with a standard base, Acetic Acid 80% converts to metal acetate and water.

Reduction of Acetic Acid 80% gives ethanol.
The OH group is the main site of reaction, as illustrated by the conversion of Acetic Acid 80% to acetyl chloride.
Other substitution derivatives include acetic anhydride; this anhydride is produced by loss of water from two molecules of Acetic Acid 80%.
Esters of Acetic Acid 80% can likewise be formed via Fischer esterification, and amides can be formed.
When heated above 440 °C (824 °F), Acetic Acid 80% decomposes to produce carbon dioxide and methane, or to produce ketene and water:
CH3COOH → CH4 + CO2
CH3COOH → CH2=C=O + H2O
REACTIONS WITH INORGANIC COMPOUNDS OF ACETIC ACID 80%:
Acetic Acid 80% is mildly corrosive to metals including iron, magnesium, and zinc, forming hydrogen gas and salts called acetates:
Mg + 2 CH3COOH → (CH3COO)2Mg + H2
Because aluminium forms a passivating acid-resistant film of aluminium oxide, aluminium tanks are used to transport Acetic Acid 80%.
Containers lined with glass, stainless steel or polyethylene are also used for this purpose.
Metal acetates can also be prepared from Acetic Acid 80% and an appropriate base, as in the popular "baking soda + vinegar" reaction giving off sodium acetate:
NaHCO3 + CH3COOH → CH3COONa + CO2 + H2O
A colour reaction for salts of Acetic Acid 80% is iron(III) chloride solution, which results in a deeply red colour that disappears after acidification.
A more sensitive test uses lanthanum nitrate with iodine and ammonia to give a blue solution.
Acetates when heated with arsenic trioxide form cacodyl oxide, which can be detected by its malodorous vapours.

PREPARATION OF ACETIC ACID 80%:
Acetic Acid 80% is produced industrially via the carbonylation of methanol.
The chemical equations for the three steps involved in this process are provided below.
CH3OH (methanol) + HI (hydrogen iodide) → CH3I (methyl iodide intermediate) + H2O
CH3I + CO (carbon monoxide) → CH3COI (acetyl iodide)
CH3COI + H2O → CH3COOH (Acetic Acid 80%) + HI
Here, a methyl iodide intermediate is generated from the reaction between methanol and hydrogen iodide.
This intermediate is then reacted with carbon monoxide and the resulting compound is treated with water to afford the Acetic Acid 80% product.
It is important to note that a metal carbonyl complex must be used as a catalyst for step 2 of this process.

When released into soil Acetic Acid 80% evaporates into the air where it is broken down naturally by sunlight.
Levels of Acetic Acid 80% in the environment would be expected to be low.
PROPERTIES OF ACETIC ACID 80%:
Acetic Acid 80% is a smooth, colourless liquid with a 1 ppm visible, poisonous and destructive, unpleasant vinegar odour.
The melting point of Acetic Acid 80% is 16.73 ° C and the usual 117.9 ° C boiling point.
At 20°C, the density of pure Acetic Acid 80% is 1.0491.
It is highly hygroscopic Acetic Acid 80%.
It is possible to link the purity of the water solutions to their freezing point.
In carboxylic acids such as Acetic Acid 80%, the hydrogen centre in the carboxyl group −COOH can differentiate from the molecule by ionization:
Due to this proton H+1 release, Acetic Acid 80% has an acidic character.
Acetic Acid 80% is a weak monoprotic acid.
Acetic Acid 80% has a pK value of 4.76 in an aqueous solution.
Acetate CH3COO−1 is the conjugate base.
For polar and non-polar solvents such as acid, chloroform, and hexane, Acetic Acid 80% is miscible.
The molecules form chains in solid Acetic Acid 80%, with hydrogen bonds interconnecting individual molecules.
Dimers can be found in the vapour at 120 °C.
In the liquid form, dimers often exist in dilute solutions in non-hydrogen-bonding solvents and, to a certain degree, in pure Acetic Acid 80%; but are interacted with by solvents that bind to hydrogen.
Acetic Acid 80% is normally completely ionized to acetate at physiological phis.
Acetic Acid 80% is central to the metabolism of carbohydrates and fats when bound to coenzyme A.

DEHYDRATION OF ACETIC ACID 80%:
Dehydration of Acetic Acid 80% is one of the most important industrial uses of AD in the manufacture of aromatic acids such as terephthalic acid (TA), which involves a high purity of Acetic Acid 80%.
Two major parts are used in the manufacturing process: oxidation (where p-xylene is catalytically oxidized to produce crude TA) and PTA purification.
Acetic Acid 80%, present as a solvent in the oxidation reactor but also helpful to the reaction itself, must be isolated from the oxidation-produced water.
For the effective and economical operation of a TA facility, the recovery and storage of the Acetic Acid 80% solvent are important.
At high water temperatures, water, and Acetic Acid 80% show a pinch point, make recovering the pure acid very difficult.
Two absorbers (low and high pressure) and an acid dehydration column consist of a traditional Acetic Acid 80% recovery unit in a PTA phase.
Tall columns of 70–80 trays require the separation of Acetic Acid 80% and water by traditional distillation.
N-butyl acetate, which exhibits minimal miscibility with water and forms a heterogeneous azeotrope (b.p. 90.23°C), which is a typical azeotropic agent.
With all the water being fed to the dehydration column, n-Butyl acetate is added in appropriate amounts to form an azeotrope.
On condensation, the heterogeneous azeotrope forms two phases; an organic layer containing almost pure n-butyl acetate and an aqueous layer phase containing almost pure water.
The organic phase is recycled back to the column of dehydration, while the aqueous phase is fed to a column of stripping.
The amount of Acetic Acid 80% lost in the aqueous discharge is cut by approximately 40 per cent as AD results in a cleaner separation.
