Abstract: By the method the ammonium sulphate formed during the manufacture of acrylonitrile by direct ammoxidation (reaction between ammonia and oxygen) of propylene or propane, ammonia and ogygen-containing gas, such as air on catalyst fluidized bed fitted in respective reactor, is eliminated to a great extent or completely. In the reactor organic substance, or substances, respectively, are introduced which react with practically all the residual ammonia without this affecting the acrylonitrile yield. It is preferable that the organic substance should be methanol which is introduced in the reactor at temperatures bellow the points of its carbonization.

Abstract: OXIDATION CATALYSTS The invention is an oxidation catalyst which contains at least a Group IIA or Group IIB element or manganese plus as required elements, chromium, bismuth and molybdenum. The catalysts can optionally contain a number of other elements and are useful for various oxidation reactions, especially the ammoxidation of propylene or isobutylene to obtain acrylonitrile or methacrylonitrile, the oxidation of propylene or isobutylene to obtain acrolein or methacrolein and the oxidative dehydrogenation of olefins containing 4 or 5 carbon atoms to obtain the corresponding diolefin.
