Abstract: An improved vanadium-phosphorus mixed oxide is prepared by a unique method employing an organic medium. The substantial intrinsic surface area and the microcrystalline structure of the new oxide result in advantageous activity and selectivity effects in the catalyzed vapor phase oxidation of n-butane to maleic anhydride. These oxides are also useful for the production of acid anhydrides from suitable hydrocarbon feeds.
