Abstract:
1. A process of making a catalyst composition for production of an unsaturated carboxylic acid from an alkane comprising: a) forming a solution of a molybdenum compound, a vanadium compound, an antimony compound, a niobium compound and a compound of gallium; b) mixing the solution to form a uniform solution; c) removing liquid from the uniform solution to form a solid; d) drying the solid; e) calcining the solid to form a catalyst of the formula: wherein Mo is molybdenum, V is vanadium, Sb is antimony, Nb is niobium, Ga is gallium, a is from 0.01 to 1, b is 0.01 to 1, c is 0.01 to 1, d is 0.01 to 1, and x is determined by the valence requirements of the other elements present.
