ABSTRACT:
V-P complex catalysts and metal promoted V-P complex catalysts having high activity and selectivity and good physical strength for the oxidation of alkenes, alkanes, cycloalkanes and mixtures rich in them to dicarboxylic acid anhydrides (e.g. maleic anhydride) are prepared by forming a paste of a vanadium compound (vanadium pentoxide), an organic reducing agent, a promoter metal salt or compound (if used), and phosphoric acid; and drying paste.
