Abstract

1487765 Oxidation catalysts NIPPON ZEON CO Ltd 14 Nov 1974 [22 Nov 1973 14 March 1974] 49345/74 Heading B1E [Also in Division C2] Catalysts have the empirical formula: Mo 12 P 0.1-8 V 0.1-8 L 0.1-8 M 0- 6 O f wherein L is Tl, Rb, Cs and/or K and M is Sr, Zn, Cd, Nb, B, Pb, Bi and/or W. The catalysts may be diluted with an inert diluent or supported on an inert carrier. In the examples catalysts are made by mixing aqueous solutions of ammonium molybdate, phosphoric acid and compounds of the elements L and M with a solution of ammonium metavanadate in aqueous oxalic acid, evaporating the mixture to dryness, calcining, pulverizing and screening.
