Descrição

Descrição geral

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.

Aplicação

Benzoic acid has been used in the preparation of vials for the HPLC analysis of various polyamines in biological fluids, tissues and isolated/cultured cells.
It may be employed as an intermediate in the synthesis of the following:

• paints
• pigments
• varnish
• wetting agents
• aroma compounds
• benzoyl chloride
• benzotrichloride

It may also be used to investigate the mechanism of complex addition reaction of hydroxyl radicals with various aromatic compounds.
