ABSTRACT:
Monoolefins such as propylene and isobutylene are converted to the corresponding unsaturated nitriles, acrylonitrile and methacrylonitrile, respectively, by reacting a mixture of the olefin, ammonia, and a molecular oxygen-containing gas in the presence of a catalyst containing the oxides of iron, bismuth, molybdenum, and cobalt or nickel or both, and optionally an oxide of at least one element selected from the group consisting of the alkali metals, rare earth metals, tantalum and niobium, and optionally one or more of the oxides of the elements selected from the group consisting of phosphorus and arsenic.
