Abstract: Olefins 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 molecular oxygen-containing gas in the presence of a catalyst containing the oxides of bismuth, molybdenum, iron, nickel and magnesium, at least one element selected from the group comprising potassium and cesium, and optionally one element selected from the group comprising cobalt, phosphorus, manganese, tellurium, sodium, cerium, chromium, antimony and tungsten wherein the sum of cesium and potassium is at least 0.1 to 0.4.

Abstract: By the method the ammonium sulphate formed during themanufacture of acrylonitrile by direct ammoxidation (reactionbetween ammonia and oxygen) of propylene or propane, ammonia andogygen-containing gas, such as air on catalyst fluidized bedfitted in respective reactor, is eliminated to a great extent orcompletely. In the reactor organic substance, or substances,respectively, are introduced which react with practically all theresidual ammonia without this affecting the acrylonitrile yield.It is preferable that the organic substance should be methanolwhich is introduced in the reactor at temperatures bellow thepoints of its carbonization.20 claims
