ABSTRACT:
Catalysts comprising a compound of vanadium, phosphorus and oxygen which are employed in the oxidation of n-butane to maleic anhydride are protected from contamination caused by side reactions which occur between the catalyst and steel process equipment by covering the process equipment surfaces which contact the catalyst at elevated temperatures with a coating comprising aluminum oxide.
