acetic acid
Also known as ethanoic acid, CH3COOH, the simplest carboxylic acid. Acetic acid is the acid found in vinegar and is often used as a reagent. It is also used in the preparation of pharmaceuticals, and in industry. It has a relative density of 1.049, a melting point of 16.6°C, and a boiling point of 117.9°C.
Acetic acid is manufactured by the liquid-phase oxidation of ethanal at 60°C by oxygen or air under presuure in the presence of manganese (II) ethanoate (the latter preventing the formation of perethanoic acid). Another important route is the liquid-phase oxidation of butane by air at 50 atm. and 150-250°C in the presence of a metal ethanoate.
