| General description: | Benzoic acid is an organic 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. |
