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: Exceptionally reproducible catalysts comprising vanadium and phosphorus are obtained when an aqueous oxide slurry comprising vanadium, phosphorus and a mineral acid-free, inorganic reducing agent, which is capable of reducing the vanadium in the catalyst to a valence state below +5, is heated at an elevated temperature of at least 120 DEG 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, n-butenes, 1,3-butadiene or mixture thereof.

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.
