A tin antimonate oxide complex catalyst of the formula:… AaDbTedSneSbfOx… wherein A represents one or more of the following elements: Cu, V, W and or Mo; D represents one or more of the following elements: Bi, Ti, Ge, Ce, La, Cr, Mn, Mg, Ca, Co, Ni, Nb, Ta, Ag, Zn, Cd, K, Cs, U, B, P and Eu; and wherein a is 0.001 to 10; b is 0 to 10; d is 0.001 to 10; e is 0.1 to 10; f is 1 to 20; f > a + b + d + e; and x is a number sufficient to satisfy the valence requirements of the other elements present. …<??>These multiply promoted Sn-Sb oxides are superior catalysts for the ammoxidation of olefins to the corresponding unsaturated nitriles, the selective oxidation of olefins to unsaturated aldehydes and acids, and the oxydehydrogenation of olefins to diolefins. |
