Abstract
Aromatic nitriles can be produced in high yields by ammoxidation of an alkyl-substituted aromatic compound in the presence of a catalyst containing oxides of (1) vanadium, (2) antimony and (3) at least one of uranium and chromium, even when concentration of the starting aromatic compound in the starting gas is high or mixing ratio of ammonia to the starting aromatic compound is reduced to the neighborhood of the stoichiometric equivalent.
Claims9
