Abstract: A process for oxidation and ammoxidation of hydrocarbons using catalysts having the empirical formulaBiMo.sub.a V.sub.b Sb.sub.c O.sub.xwherein a is from 0.5-2, b is from 0.12-3, c is from 0.12 to 10, d is 0-0.5 and x is selected to satisfy the valence requirements of the other elements present. 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.The catalyst is prepared by forming a slurry of vanadium antimonate component, a bismuth molybdate component, and optionally the compound M and/or a support material, drying the slurry, and calcining to form the catalyst.The process is useful for production of acrylonitrile from propylene, ammonia, and an oxygen-containing gas.

Abstract: An oxidation and ammoxidation process is disclosed which employ catalysts which have the empirical formula Sb.sub.a V.sub.b Ti.sub.C O.sub.x, wherein a is at least 6, b is 1, and c is a number such that the ratio c/a is at least 0.5, and x is a number taken to satisfy the valence requirements of the Sb, V and Ti present in the catalyst. Such catalysts may be optionally supported on conventional supports, or may be unsupported.
