Zusammenfassung:	43-21(6574)A IRON/LITHIUM - PROMOTED CATALYSTS FOR THE PRODUCTION OF MALEIC ANHYDRIDE AND A PROCESS FOR THE PREPARATION THEREOF ABSTRACT OF THE DISCLOSURE Catalysts useful for the partial oxidation of nonaromatic hydrocarbons, particularly n-butane, with molecular oxygen or an oxygen-containing gas in the vapor phase to produce maleic anhydride are provided which comprise phosphorus, vanadium, and oxygen and a promoter component containing each of iron and lithium. Such catalysts are prepared by contacting a substantially tetravalent vanadium-containing compound and a phosphorus-containing compound and a promoter component containing each of iron and lithium in a substantially anhydrous alcohol medium in the presence of anhydrous hydrogen chloride to form an iron/lithium promoted phosphorus-vanadium-oxygen catalyst precursor. The catalyst precursor is recovered, dried, roasted, formed into structures if structures are desired, and calcined.
