Description
Synonyms: Benzenecarboxylic acid, Carboxybenzene
Linear Formula: C6H5COOH
General description
Benzoic acid is an organic aromatic monocarboxylic acid. It can be synthesized by the cobalt or manganese catalyzed atmospheric oxidation of toluene. Recently, benzoic acid has been prepared from toluene by employing TiO2 nanotubes electrode.
Benzoic acid reacts with hydrogenating reagents to afford hexahydrobenzoic acid. The thermal decomposition of the product in the presence of lime or alkali produces benzene and carbon dioxide.
