ABSTRACT:
V-P-Zr catalysts having high activity and selectivity and good physical strength for the oxidation of alkanes, cycloalkanes and mixtures rich in them to dicarboxylic acid anhydrides (e.g. maleic anhydride) are prepared by reacting an aqueous mixture of vanadium pentoxide and a hydroxy-or oxo- alkanoic acid or formaldehyde, a zirconium salt, and phosphoric acid.
