CATALYSTS FOR THE OXIDATION AND AMMOXIDATION OF OLEFINS AND THEIR USE IN MAKING ACRYLONITRILE ABSTRACT OF THE DISCLOSURE Catalysts useful for the oxidation and ammoxidation of olefins have the empirical formula: FeaSbbCucTedWfMegOx Wherein Me is a member of the group consisting of V, B, P, Mg, Sn, Zn, Mn, and mixtures thereof wherein a is 5 to 10, b is 10 to 30, c is 1 to 5, d is 0.5 to 5, e is 0.1 to 5, f is 0.01 to 5, g is 0 to 0.5, and x is a number taken to satisfy the valence requirements of the other elements present. Such catalysts are prepared by forming a mixture containing iron, antimony and copper components and a preformed tellurium-containing component selected from the group consisting of tellurium molybdate, tellurium tungstate and mixtures thereof, a complementary metal- containing component and, optionally, a vanadium component, in amounts sufficient to satisfy the elemental atomic ratio requirements, forming the mixture into dry particles, and calcining to form the catalyst. These catalysts are especially useful for the production of acrylonitrile from propylene, ammonia, and an oxygen- containing gas.
