ABSTRACT:
A novel catalyst for the oxidation of butane to produce maleic anhydride comprising a phosphorus and vanadium mixed oxide wherein the catalyst is prepared by using P.sub.2 O.sub.5 in an organic medium wherein the catalyst is not precipitated. The catalyst has a specific phase identified by a characteristic X-ray diffraction pattern. A process for the manufacture of the catalyst and a process for the manufacture of maleic anhydride from butane feedstock utilizing the novel catalyst is disclosed. Maleic anhydride is a well-known industrial chemical used in the manufacture of polyester, and maleic anhydride also has utility as a food stuff.
