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.
