ABSTRACT:
A method for the preparation of catalysts useful for the oxidation and ammoxidation of olefins contain antimony, uranium, iron, bismuth, and molybdenum in a catalytically active oxidized state. The method comprises preparing a hydrated mixed oxide component containing antimony, uranium iron and bismuth, making an aqueous slurry thereof; adding a molybdate thereto; adjusting the pH, drying and calcining. The catalysts are especially useful for the production of acrylonitrile from propylene, ammonia, and an oxygen-containing gas.
