  • Patent number: 4564688
    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.

  • Patent number: 4482726
    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.
