Benzoic acid /bɛnˈzoʊ.ɪk/ is a white (or colorless) solid organic compound with the formula C6H5COOH, whose structure consists of a benzene ring (C6H6) with a carboxyl (−C(=O)OH) substituent. The benzoyl group is often abbreviated "Bz" (not to be confused with "Bn" which is used for benzyl), thus benzoic acid … See more Benzoic acid was discovered in the sixteenth century. The dry distillation of gum benzoin was first described by Nostradamus (1556), and then by Alexius Pedemontanus (1560) and Blaise de Vigenère See more Benzoic acid is mainly consumed in the production of phenol by oxidative decarboxylation at 300−400 °C: The temperature required can be lowered to 200 °C by the … See more Reactions of benzoic acid can occur at either the aromatic ring or at the carboxyl group. Aromatic ring Electrophilic aromatic substitution reaction will take place mainly in 3-position due to the See more • International Chemical Safety Card 0103 • SIDS Initial Assessment Report for Benzoic Acid from the Organisation for Economic Co-operation and Development (OECD) • ChemicalLand See more Industrial preparations Benzoic acid is produced commercially by partial oxidation of toluene with oxygen.
