Oxidation experiments of 1,3-butadiene, furan, and maleic anhydride have been performed over MnMoO{sub 4}/MoO{sub 3} catalysts and their pure-phase constituents. The effect of oxygen concentration on catalytic activity and selectivity of these catalyst has been investigated. MoO{sub 3} catalysts containing MnMoO{sub 4} as a coexisting phase have been found to be active and selective for maleic anhydride formation for all feed materials and over a wide range of oxygen concentrations. The activity of the molybdenum trioxide catalyst has been found to be least affected by the concentration of gas-phase oxygen. Partial conversion of maleic anhydride to CO{sub 2} has been observed over all three catalysts with MnMoO{sub 4} showing the highest activity for complete oxidation. 20 refs.
