| 摘要 |
The present invention provides an improved process for producing a catalyst containing the elements iron, antimony, uranium, bismuth and molybdenum in a catalytically active oxidized state, which is useful in the preparation of unsaturated nitriles by ammoxidation of olefins and in the oxidation of olefins to the corresponding unsaturated aldehydes. One embodiment of the process comprises the steps of: (a) forming a mixed oxides component that comprises oxides of antimony, bismuth, iron, and uranium; (b) combining the mixed oxides component with a molybdate; (c) forming the mixed oxides component into particles; (d) heating the particles at a temperature between about 40 DEG C and about 120 DEG C for at least about 1 hour; (e) drying the particles; and (f) calcining the particles. |
