ABSTRACT:
A process for the manufacture of a phosphorus-vanadium oxide and a phosphorus-vanadium-co-metal catalyst suitable for the oxidation of butane to maleic anhydride is disclosed. The catalyst is prepared by reacting, in an aqueous medium, a vanadium compound, inorganic acid and, if used, a metal oxide. Ortho-phosphoric acid is then added to form a soluble vanadium-phosphorus or a vanadium-phosphorus-metal catalyst. The acidified water is removed and aliphatic alcohols and either aromatic acids or aromatic anhydrides, or a mixture of these, are added and the alcohols are removed. The solid phosphorus-vanadium, or phosphorus-vanadium-metal oxide is recovered under vacuum.
