PRODUCTION OF MALEIC ANHYDRIDE BY THE OXIDATION OF BUTANE AND CATALYSTS THEREFOR

摘要

A novel catalyst for the oxidation of butane to produce maleic anhydride comprising a phosphorus and vanadium mixed oxide promoted by zinc wherein the catalyst is prepared by using an organic medium and has two specific phases identified by characteristic X-ray pattern. A process for the manufacture of maleic anhydride from butane fedstock utilizing the novel catalyst is also disclosed.
