Abstract

1351218 Maleic anhydride BADISCHE ANILIN- & SODA-FABRIK AG 18 June 1971 [19 June 1970] 28669/71 Heading C2C [Also in Division B1] Maleic anhydride is prepared by gas phase oxidation of n-C 4 olefin with molecular oxygen in the presence of catalyst which comprises anatase, vanadium pentoxide and phosphorus pentoxide and which has been prepared by a process wherein anatase powder, a vanadium compound and a phosphorus compound are mixed in the presence of water (the vanadium and phosphorus compounds being vanadium pentoxide and phosphorus pentoxide or compounds convertible thereto on heating in the presence of air at a temperature not exceeding 250‹ C., for example ammonium vanadate, vanadyl formate, vanadyl oxalate, phosphoric acid, pyrophosphoric acid) and the resulting mixture is dried, heated in air at a temperature not exceeding 250‹ C. (thereby to convert any such convertible vanadium and phosphorus compounds, if present, into pentoxide), reduced in size and shaped. The catalyst may consist of 80-88 weight per cent anatase, 2-5 weight per cent vanadium pentoxide and 10-15 weight per cent phosphorus pentoxide. As exemplified, maleic anhydride is prepared by contacting air and a crude C 4 hydrocarbon cut containing 63 weight per cent C 4 olefin with a fixed bed of catalyst (including comparison catalyst) prepared by a procedure wherein anatase, phosphoric acid and an aqueous solution prepared from vanadium pentoxide and oxalic acid are mixed and the resulting mixture is dried, reduced in size, heated for six hours at a temperature of from 200‹ to 500‹ C., powdered, made into paste with water, moulded into pellets and dried.
