Acetic acid (Science: chemical) The acid most commonly associated with vinegar, it is the most commercially important organic acid and is used to manufacture a wide range of chemical products, such as plastics and acetobacter but, except for making vinegar, is usually made through synthetic processes. derivatives of acetic acid which may be formed by substitution reactions. Mono- and di-substituted, as well as, halogenated compounds have been synthesised. Experimentally, alpha- and n2- substituted acetic acids have been examined for their anti-inflammatory activity and effect on the central nervous system respectively. Additionally, limited exposure data has been collected on dibromo and dichloroacetic acids to determine whether they pose health effects. Synonym: ethanoic Acid. A colorless pungent liquid widely used in manufacturing plastics and pharmaceuticals.A transparent liquid that is part of vinegar, that gives it its characteristic smell.

Acetic Acid: What is it? Acetic Acid is an organic acid formed when ethanol is fermented. Vinegar is typically a 5% solution of Acetic Acid. Brown Rice Vinegar is the vinegar produced by the fermentation of unpolished brown rice. Natural Vinegars also contain also contain small amounts of tartaric acid, citric acid and other acids.
In cosmetics and personal care products, Acetic Acid, Vinegar and Brown Rice Vinegar are used in the formulation of hair conditioners, shampoos, hair rinses, wave sets and other hair care products. Acetic Acid is also used in mouthwashes and breath fresheners and Vinegar can be found in skin care products.

Local: Acetic acid is the simplest carboxylic acid next to formic acid in which a single hydrogen atom is attached to the carboxyl group. If a methyl group is attached to the carboxyl group, the compound is acetic acid. Acetic acid is a clear, corrosive, flammable liquid; melting point 16.6 C, boiling point 118 C. Pure acetic acid freezes in ice-like crystal form. So pure acetic acid is called glacial acetic acid, which contains 99.5 -100.5 % w/w. It is the two-carbon carboxylic acid, and a systematic name is ethanoic acid. It is completely miscible with water, ethyl alcohol and ether, but is insoluble in carbon disulfide. It is a characteristic component of vinegar and an important biochemical intermediate in the form of acetylcoenzyme A, mostly. Most commercial production of virgin synthetic acetic acid is based on  methanol carbonylation. Significant volumes of acetic acid are recovered in cellulose acetate operations and lesser quantities during production of polyvinyl  alcohol and butyral, peracetic acid, ethylene-vinyl alcohol and acetaminophen and aspirin. Capacity utilization is likely to remain high for the next few years because of good demand for purified terephthalic acid and vinyl acetate monomer.

Vinyl acetate monomer

The largest consumption of acetic acid is as a raw material to produce vinyl acetate by reaction with ethylene and oxygen or with acetylene in the presence of  palladium catalyst. Vinyl acetate is polymerized to polyvinyl acetate by itself and to other copolymers with other monomers. Acetate polymers are important resins used in paints, adhesives, plastics and textile finishes.

Acetic anhydride

The next largest consumption of acetic acid is to produce acetic anhydride by condensation reaction of two acetic acid molecules. This chemical is principally used in the manufacture of cellulose acetate having the application as a base for magnetic tape and in the manufacture of textile fibres. Also, it is heated with salicylic acid to produce acetylsalicylic acid (aspirin). It is also used in the manufacture of pigments, dyes, cellulose and pesticides etc.

Solvent

Acetic acid is used as a solvent in the production of terephthalic acid from p-xylene. Terephthalic acid is the raw material for polyester fiber. Terephthalic acid has become a more important raw material for non-fiber field, PET-bottle, PET-film and engineering plastics and as poultry feed additives.

Esters

Considerable quantities of acetic acid are used to manufacture esters such as ethyl and butyl acetate. Acetate esters demonstrate good solvency for many natural and synthetic resins. They are general purpose solvents which are applied commonly in lacquer thinners, wood lacquers and a wide variety of coatings, plasticizer and pharmaceutical fields.

Chloroacetic acid

The stronger acid (chloroacetic acid) is manufactured from acetic acid by reaction with chlorine. Chloroacetic acid reacts with alkali cellulose to produce carboxymethylcellulose (CMC). Chloroacetic acid is the parent material for the production of a series of phenoxy herbicides such as 2,4-dichlorophenoxyacetic acid and 2,4,5-trichlorophenoxyacetic acid.

Acetic acid is used as an acidulant in a wide range of applications from eletroplating to textiles finishing operation. It is used in the manufacture of materials used in the pharmaceuticals, foods, cosmetics and colorant chemical fields including sorbic acid, dyestuffs and pigments, vitamins, antibiotics, rubber chemicals and flavor & fragrance.
