General description

Benzoic acid is an aromatic monocarboxylic acid. It occurs in the form of colorless leaflets or needles. It reacts with hydrogenating reagents to afford hexahydrobenzoic acid. On decomposition (by heating) in the presence of lime or alkali, it affords benzene and carbon dioxide. It can be synthesized by the cobalt or manganese catalyzed atmospheric oxidation of toluene.
