Abstract: A process for the preparation of oxidation catalysts containing mixed oxides of vanadium and phosphorus comprises… a) introducing a pentavalent vanadium-containing compound into a liquid medium capable of reducing the valence state of said vanadium;… b) effecting reduction of at least a portion of said vanadium to a valence state of approximately +4;… c) adding a mixed phosphorus component comprising orthophosphoric acid and pyrophosphoric acid to said medium prior to or subsequent to effecting said reduction to form a catalyst precursor;… d) recovering the catalyst precursor;… e) drying the catalyst precursor;… f) calcining the catalyst precursor;…… Improved results are obtained by the use as the mixed phosphorus of component one containing orthophosphoric and pyrophosphoric acid. … The catalyst are useful in the oxidation of C4 hydrocarbons to maleic anhydride.
