ABSTRACT OF THE DISCLOSURE Dislosed herein are catalysts useful for oxidation and ?mmoxidation of hydrocarbons. Such catalysts have the empirical formula BiMoaVbSbcMdOx wherein a is 0.5-2, b is 0.01-0.12 c is 0.01-10, d is 0-0.5 and x is selected to satisfy the valence require- ments of the other elements present. in such catalysts, M is one or more elements selected from Groups I-A, II-A, III-A, V-A, VI-A, I-B, IV-B, VI-B and VII-B of the Periodic Table. Catalysts according to the invention are pre- pared by forming a slurry of a vanadium component, an antimony component, a hydrophilic bismuth molybdate component having the empirical formula BiMoaOx?Y(H2O) wherein a is 0.5-2, x is selected to satisfy the valence requirements of the bismuth and molybdenum and Y is is a number such that the bound water is 5 to 40 weight per- cent of the total component, and optionally, the com- pound M and/or a support material, drying the slurry, and calcining to form the catalyst. Such catalysts are specifically useful for production of acrylonitrile from propylene, ammonia and an oxygen-containing gas.
