ABSTRACT:
A method of optimizing the yield of a vanadium-phosphorus catalyst during the oxidation of butane to maleic anhydride, which comprises establishing the temperature at which the catalyst provides the desired percentage conversion and yield of maleic anhydride with the established feed composition and then maintaining that temperature by continuously introducing an amount of a suitable phosphorus compound necessary to prevent a decline in selectivity to maleic anhydride without significantly increasing the temperature.
