ABSTRACT:
Vanadium phosphorus mixed oxide containing catalysts are prepared in an organic liquid reaction medium with heating wherein at least 1.5 moles organic liquid are removed from the reaction medium such as by distillation for each mole of vanadium which is reduced or reacted during such reaction and/or reduction. The resulting catalysts are useful for the production of maleic anhydride from 4 carbon atom hydrocarbons.
