Abstract
1413192 Oxidation catalyst KURARAY CO LTD 28 Nov 1973 [4 Dec 1972 (4)] 55141/ 73 Heading B1E [Also in Division C2] Catalysts consist of the oxides of tungsten and phosphorus and, as catalyst promoter, at least one compound of an element belonging to Group IIIA, IIIB or VIII of the Periodic Table or of carbon, silicon, germanium, tin, lead, zirconium, arsenic, niobium or antimony. In one method of catalyst preparation a tungsten compound is first calcined in air to obtain tungsten oxide which is mixed with phosphoric acid diluted with water and a catalyst promoter and the mixture heated to obtain a paste. The paste is moulded and dried to obtain the catalyst which, by subsequent calcination, can be converted to a more stable and active catalyst. The catalyst may be supported on a carrier and the supported catalyst used in situ in the reaction.
