AMMOXIDATION CATALYST COMPOSITION AND PROCESS FOR PRODUCING ACRYLONITRILE OR METHACRYLONITRILE BY USING THE SAME |
摘要 |
An ammoxidation catalyst composition for use in the production of acrylonitrile or methacrylonitrile from propylene, isobutene or t-butanol, which composition contains an oxide catalyst composition represented by the general formula: MO12(Bi1-aCea)bFecNidXeYfOg (wherein X is at least one element selected from magnesium and zinc; Y is at least one element selected from potassium, rubidium and cesium; a=0.6-0.8; b=0.5-2; c=0.1-3; d=4-10; e=0-3; f=0.01-2; and g is the number of oxygen atoms necessary for satisfying the requirement for the valences of other elements). The use of this composition gives a high yield of acrylonitrile or methacrylonitrile and prevents the yield from being lowered even in the long run. |
