Abstract: In the vapor phase ammoxidation of organic compounds to form nitriles where a reactant stream of ammonia and organic reactant is passed over catalyst, the improvement which comprises pretreating the catalyst with the organic reactant before admitting the reactant stream to the reactant system, whereby the conversion to nitriles is significantly increased.
