摘要：1357848 Oxidation catalysts NIPPON KAYAKU KK 25 May 1972 [26 May 1971] 24569/72 Heading B1E [Also in Divisions C2 and C5] Catalysts of general composition Co a Fe b Bi c Mg d Mo f M h O g , where M is at least one of K 1 , Cs and Kb and a is 1-15; bis 0.5-7; c is 0.1-4; d is 0-4; f is 12; h is 0.1-1.0 and g is 39-72 (being determined from the valencies of the other elements), on a silica support, may be prepared by adding cobalt, ferric, bismuth and M nitrates and magnesium nitrate (where used) to an ammonium molybdate/silica suspension, evaporating to dryness and calcining at 700‹C in an air stream. These may be used to catalyse the ammonoxidation and oxidative dehydrogenation of a mixed butane-butene gaseous feed to methacrylonitrile and 1,3- butadiene.
