Abstract

Acrylonitrile or methacrylonitrile are prepared by reacting at an elevated temperature in the vapour phase propylene or isobutene with oxygen and ammonia over an oxidation catalyst comprising a mixture of the oxides of molybdenum and cobalt, and/or a compound of molybdenum, cobalt and oxygen. The catalyst may be deposited on a silica or alumina support and may also be admixed with a proportion of tellurium oxide. The process may be carried out with a fixed bed or a fluidised bed of catalyst and the reactant streams may be diluted with inert gases such at nitrogen, propane, butane, isobutane, carbon dioxide and steam. Reaction temperatures may range from 300 to 500 DEG C. and ammonia is preferably used in stoichiometric excess. Specification 709,337 is referred to.ALSO:Catalysts comprising a mixture of the oxides of molybdenum and cobalt, and/or a compound of molybdenum, cobalt and oxygen, are prepared (1) by mixing an aqueous solution of a cobalt salt with an aqueous solution or suspension of molybdic acid or a molybdic acid salt, adding ammonia or a water-soluble aliphatic amine such as ethanolamine to the aqueous mixture, drying the precipitate, and heating it to between 400 and 700 DEG C.; (2) by forming an aqueous solution of a cobalt salt and ammonium molybdate, heating the mixture until a precipitate forms, and drying and heating as in (1); and (3) by adding ammonia or a water-soluble amine to an aqueous solution of a cobalt salt, mixing the resulting precipitate with molybdic acid or a salt of molybdic acid and a volatile base either as such or as a solution or suspension in water, and drying and heating as in (1). The catalyst may be optionally admixed with tellurium dioxide and, if desired, supported on a silica or alumina carrier. Specification 709,337 is referred to.
