Abstract: The present invention provides a method for the preparation of oxidation catalysts containing mixed oxides of vanadium and phosphorus, 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 high yields of maleic anhydride with good selectivity. Vanadium phosphorus mixed oxide catalyst precursors prepared in solution in organic media are extracted from the organic media with water, with subsequent drying down to recover a precursor solid, or impregnation of a support with the aqueous solution.
