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
