ResumoThe influence of phosphorus on the selectivity in maleic anhydride from n-butane is examined on vanadium-phosphorus catalysts prepared in an organic medium. A deficiency of phosphorus with respect to a P:V atomic ratio of 1.0 enhances the rate of maleic anhydride decomposition, consequently leading to lower yields of maleic anhydride at high conversion. An excess of phosphorus limits the rate of maleic anhydride decomposition, but decreases both the activity of the catalyst and the ratio of the two parallel rates of maleic anhydride and carbon oxides formation from n-butane.
