Abstract: Vanadium-free catalysts consisting essentially of oxides of titanium and phosphorus have been found to be especially effective in the oxidation of n-butane, n-butenes and 1,3-butadiene with molecular oxygen in the vapor phase to yield maleic anhydride. The reaction with n-butane gives an especially pure product in good yield and selectivity.

Abstract: Catalysts containing the oxides of vanadium, phosphorus and uranium have been found to be especially effective in the oxidation of n-butane, n-butenes and butadiene with molecular oxygen in the vapor phase to yield maleic anhydride. The reaction with n-butane gives an especially pure product in high yield.

Abstract: Vanadium phosphorus mixed oxide containing catalysts are prepared by sequentially forming an alpha-VOPO4 catalyst precursor in aqueous media, and thereafter partially reducing a portion of the vanadium to a valence state of +4 in an organic liquid reducing media, in the absence of corrosive reducing agents. The catalysts exhibit excellent activity for the production of maleic anhydride from 4 carbon atom hydrocarbons such as n-butane.

Abstract: PRODUCTION OF MALEIC ANHYDRIDE FROM FOUR-CARBON HYDROCARBONS USING CATALYSTS PREPARED BY HYDROTHERMAL TECHNIQUES Exceptionally reproducible catalysts comprising vanadium and phosphorus are obtained when an aqueous oxide slurry comprising vanadium, phosphorus and a mineral acidfree, inorganic reducing agent, which is capable or reducing the vanadium in the catalyst to a valence state below +5, is heated at an elevated temperature of at least 120.degree.C under autogenous pressure so that substantial evaporation of the water in said oxide slurry is prevented. Especially preferred catalysts comprise vanadium, phosphorus, uranium and oxygen. Catalysts prepared in accordance with the invention are especially desirable in the oxidation of n-butane, nbutenes, 1,3-butadiene or mixture thereof.
