A process for the production of aromatic nitriles comprises contacting (a) an aromatic hydrocarbon selected from the group consisting of alkyl-substituted benzenes with 1-3 alkyl groups of 1-4 C atoms, alkyl substituted naphthalenes with 1-2 alkyl groups of 1-4 C atoms and alkyl substituted diphenyls with 1-2 alkyl groups of 1-4 C atoms, (b) oxygen, and (c) ammonia at a temperature of from 300 DEG -500 DEG C. and at a pressure of from 400 mm Hg to 2 atmospheres with a catalyst consisting substantially of a member selected from the group consisting of vanadium oxide and a mixture of vanadium oxide and chromium oxide, the catalyst being supported on an alumina carrier made up of at least one member of the group consisting of g -, d -, c -, K- and X-alumina. The reaction may be carried out for example by passing the gas mixture at the reaction temperature over the catalyst, then cooling the reaction gas and separating the nitriles by condensation, if desired by spraying in water. Several examples are given using xylene, toluene, diisopropylbenzene, 3,4-dimethyldiphenyl, 1 methyl naphthalene and mesitylene as starting materials. |
