Abstract
Benzophenone and derivatives thereof are prepared from diphenylmethane, benzyltoluene and other derivatives of diphenylmethane with one or more nuclear substituted aliphatic side chains and nuclear substitution products of such compounds in which the substituents may be halogens, nitro or sulphonic groups, by oxidizing them with nitric acid of 10-50 per cent concentration under superatmospheric pressure at a temperature exceeding 100 DEG C. Preferably the reaction is carried out under a pressure of 20-70 kg/cm2 and at a temperature of at least 150 DEG C. Suitably a part only of the nitric acid is used to initiate the reaction the remainder being added subsequently. The reaction may be carried out continuously in an autoclave or vertical tube using high pressure pumps or pressure containers to supply the reactants, the reaction product being simultaneously discharged. In examples: (1) diphenylmethane is oxidized to benzophenone and (2) and (3) benzyltoluene (mixed isomers) is oxidized to benzoylbenzoic acid.
