Abstract of the Disclosure In accordance with the process of this in- vention, an improved catalyst for molecular oxidation of an aromatic hydrocarbon to form the corresponding aromatic carboxylic anhydrides is prepared by the steps of forming a catalyst precursor by depositing on titanium dioxide solids in the anatase form a discon tinuous monolayer amount of at least one source of tantalum oxide, calcining the thus-formed catalyst precursor under conditions sufficient to convert the tantalum oxide source into the oxide form, depositing upon the calcined catalyst precursor a catalytically effective amount of at least one vanadium compound which is convertible into vanadium oxide upon heating and calcining the vanadium-deposited solids under con- ditions sufficient to convert the vanadium compound into vanadium oxide.
