    Abstract: 1,233,491. Ammoxidation catalysts. UBE INDUSTRIES Ltd. 14 March, 1969 [2 July, 1968; 12 July, 1968], No. 13690/69. Heading B1E. [Also in Divisions C1 and C2] An ammoxidation catalyst comprises 95-50 parts wt. of a bismuth antimonate in which the atomic ratio of bismuth to antimony is 1:1, containing less than 10% wt. of other bismuth antimonates and 5-50 parts wt. of a bismuth molybdate and/or bismuth tungstate in which the atomic ratio of bismuth to molybdenum or tungsten is 2:3, containing less than 20% wt. of other bismuth molybdates or tungstates. The catalyst may be supported, e.g. by silica, alumina, alumina-silica, silicates or carborundum, inactivated by treatment at elevated temperatures. Surface areas of 1 to 3 m 2 /g are disclosed.
