Abstract
Mixed oxides of bismuth with other metals of the perovskite structure and having vacant lattice sites in the same lattice positions occupied by bismuth are disclosed as partial oxidation and ammoxidation catalysts. Such oxides are used as catalysts in the improved method of oxidizing an acyclic hydrocarbon of 1-10 carbons having at most one olefinic unsaturation by reacting the acyclic hydrocarbon in the vapor phase with oxygen in the presence of the solid catalyst to form products having carbon, hydrogen and oxygen.
