Catalysts for the oxidation of hydrocarbons which contain V, Mo, Bi, and O, are prepared by modifying the crystal structure of biVO4 by incorporating Mo atoms. The catalysts have many uses, a particularly valuable usage being in the prodn. of unsaturated nitriles. by the reaction of a mixture of olefines ammonia, and oxygen or air. In particular, when propylene is employed as the olefin, the product is acrylonitrile, together with small amounts of acetonitrile and hydrogen cyanide. |
