Abstract
Acrylonitrile or methacrylonitrile are prepared by reacting propylene or isobutene at an elevated temperature in the vapour phase with oxygen and ammonia over an oxidation catalyst comprising (i) a mixture of the oxides of antimony and tin, and/or (ii) a compound of antimony, tin and oxygen (see Group III).ALSO:Catalysts suitable for the production of acrylonitrile and methacrylonitrile (see Group IV(b)) comprise (i) a mixture of the oxides of antimony and tin, and/or (ii) a compound of antimony, tin and oxygen, such as tin antimonate. The catalyst may be prepared from the oxides or from compounds, such as the hydroxides, which on heating in the presence of an oxygen-containing gas are converted to the oxides. Specified oxides are antimony trioxide, tetroxide and pentoxide and their mixtures; stannic oxide, stannous oxide, metastannic acid and their mixtures. Hydrated forms of the oxides may be used, such as those formed by the action of aqueous nitric acid on antimony or tin metals or their mixtures. The catalyst mixture may be pre-heated in the presence of an oxygen-containing gas such as air, for instance at a temperature between 550 and 1100 DEG C. Cationic salts of the metals, such as the chlorides may be hydrolysed with water or aqueous ammonia and the resulting precipitate heated. The catalyst may be supported, e.g. on silica.
