Applicazioni

Acetic acid is used as a solvent for purification and production of many chemical compounds eg., vinyl acetate monomer. It is a significant chemical reagent and is mainly used in the production of cellulose acetate for photographic film, polyvinyl acetate for wood glue, synthetic fibers and fabrics. It is used as a descaling agent in households. As a food additive, it finds application as a condiment, in the pickling of vegetables and other foods and is also an acidity regulator. In analytical chemistry, for the estimation of weakly alkaline substances such as organic amides, glacial acetic acid is used. Acetic acid is used as antimicrobial preservative or acidulates in a variety of food products.

Note

Incompatible with oxidizing agents, soluble carbonates and phosphates, hydroxides, metals, peroxides, potassium permanganate, amines, alcohols and nitric acid.
