Acetic Acid, systematically named ethanoic acid, is colourless liquid organic compound, when undiluted, it is sometimes called glacial acetic acid. Acetic acid has a distinctive sour taste and pungent smell. In addition to household vinegar, it is mainly produced as a precursor to polyvinyl acetate and cellulose acetate.

Acetic Acid classified as a weak acid since it only partially dissociates in solution, but concentrated acetic acid is corrosive and can damage skin. Acetic acid is the second simplest carboxylic acid (after formic acid). It consists of a methyl group attached to a carboxyl group. It is an important chemical reagent and industrial chemical, used primarily in the production of cellulose acetate for photographic film, polyvinyl acetate for wood glue, and synthetic fibres and fabrics. In households, diluted acetic acid is often used in descaling agents. In the food industry, acetic acid is controlled by the food additive code E260 as an acidity regulator and as a condiment. In biochemistry, the acetyl group, derived from acetic acid, is fundamental to all forms of life. When bound to coenzyme A, it is central to the metabolism of carbohydrates and fats.

The global demand for acetic acid is about 6.5 million metric tons per year (Mt/a), of which approximately 1.5 Mt/a is met by recycling; the remainder is manufactured from methanol. Vinegar is mostly dilute acetic acid, often produced by fermentation and subsequent oxidation of ethanol.

Acetic Acid Applications & Usage

  • Acetic acid is primarily used as a raw material for the manufacture of vinyl acetate (VAM). It is used as a reaction promoter in terephthalic acid production and is also a raw material for cellulose acetate, acetate esters, acetic anhydride, chloroacetic acid and a wide range of industrial synthesis.
  • Acetic acid is used in many industrial processes for the production of substrates and it is often used as a chemical reagent for the production of a number of chemical compounds like acetic anhydride, ester, vinyl acetate monomer, vinegar, and many other polymeric materials.
  • It is also used to purify organic compounds as it can be used as a solvent for recrystallization.
  • Acetic acid is used for the manufacture of inks and dyes and it is also used in making perfumes. In pigments and textile printing industry, it mainly for the production of disperse dyes and vat dyes, and textile printing and dyeing.
  • In the natural rubber industry used as coagulant.
  • It is also widely used in water treatment, synthetic fiber, pesticide, plastics, leather, coating, metal processing, rubber and plastic industries
  • In food – Acetic acid is used as a sour agent added in vinegar, pickled vegetables, and sauce, and as a raw material for spice
  • In Cleaning – Acetic acid is the acid in clear white vinegar and is a natural all-purpose cleaning agent. It is best for general household cleaning on surfaces that can tolerate a strong, acidic product. After using alkaline cleaners, acetic acid can be used as a mild deliming rinsing agent.
