Allgemeine Beschreibung

Benzoic acid is an organic aromatic monocarboxylic acid. 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.

Anwendung

Benzoic acid may be employed as a standard in the quantitative and calorimetric studies. It may be employed as an intermediate in the following syntheses:
  • paints
  • pigments
  • varnish
  • wetting agents
  • aroma compounds
  • benzoyl chloride
  • benzotrichloride
