摘要： Exceptionally reproducible catalysts comprising vanadium and phosphorus are obtained when the catalysts are prepared in an aqueous oxide slurry comprising vanadium, phosphorus and a mineral acid-free, inorganic reducing agent, which is capable of reducing the vanadium in the catalyst to a valence state below +5. Additional promoters may be selected from the group of elements of Group IB through VIB, VIII, lanthanides, actinides, and IA through VIA, excluding the elements H, N, O, C, Fr, Ra, and Po. Catalysts of particular interest consist of the elements vanadium, phosphorus, oxygen, and optionally at least one of Ta, Ce, Cr, Mn, Co, S, Cu, Sb, Fe, Bi, W, Mo, Hf, Zr, Th, an alkali metal and an alkaline earth metal.

摘要： The present invention provides improved oxidation catalysts containing mixed oxides of vanadium and phosphorus and the method for the preparation thereof, which catalysts are particularly effective in the oxidation of n-butane, n-butenes, 1,3-butadiene or a mixture thereof with molecular oxygen or an oxygen-containing gas in the vapor phase to produce excellent yields of maleic anhydride with very good selectivity. At least one vanadium compound, a substantial portion of which is in the pentavalent state, and at least one phosphorus-containing compound is added to an organic liquid medium capable of reducing at least a portion of the vanadium to a +4 valence state, to form a reaction mixture. Partial reduction of the vanadium is effected in the presence of the phosphorus-containing compound and a highly ordered and uniform mixed vanadium phosphorus oxide-containing catalyst precursor is formed.
