    Abstract: In a process for the preparation of acrylonitrile and methacrylonitrile by the oxidation of propylene or isobutylene with oxygen or gases containing oxygen in the presence of ammonia at an elevated temperature, a tin salt of a boromolybdate heteropoly acid on a carrier is used as a catalyst. The weight ratio of stannic oxide to molybdenum oxide is from 10:1 to 1:10, and of boron oxide to molybdenum oxide is from 1:5 to 1:20. and the preferred carrier is silica gel. The catalyst may be prepared by impregnating the carrier with solutions of tin, boron and molybdenum salts, or by coprecipitation of silica gel and tin, boron, molybdate, followed by drying, and the use of a fluidized bed method is preferred.ALSO:Aminoxidation catalyst comprise tin salts of a boromolybdate heteropoly acid supported on a carrier. The weight ratio of stannic oxide to molybdenum oxide is from 10:1 to 1:10, and of boron oxide to molybdenum oxide is from 1:2 to 1:50 and silica gel is preferred as the carrier. The carrier may be impregnated with suitable solutions of tin, boron, molybdenum salts and dyed, silica-gel may be co-precipitated with tin boron molybdate, or the tin salt of boromolybdic acid may be applied in molten form preferably in the presence of a flux e.g. urea or oxalic acid. The particle size is determined by spraying, extrusion or by grinding. In examples of catalyst preparation, boric acid is added to ammonium molybdate solution followed by stannous chloride solution, the solution made alkaline with ammonia, and silica gel kneaded is followed by dying and annealing; ammonium molybdate and boric acid solution is stirred into silica sol and during heating and mixing an acetic acid solution of stannous oxide is flowed in, the mixture is evaporated and calcined.

    Abstract: Acrylonitrile (or methacrylonitrile) from propylene (or isobutylene) is made by ammoxidation at elevated temperature using supported catalysts containing MoO3 and SuO2 and optionally BrO3, the catalyst having been prepared by impregnating the carrier with a solution of the metal oxides on the corresponding sulphates in conc. H2SO4, followed by drying. Examples describe the passage of gaseous mixtures of olefine + oxygen + ammonia + nitrogen and/or steam over suitably prepared catalysts at 480-500 DEG C.ALSO:Catalysts of MoO3, SuO2 \sB B2O3 on a carrier are made by impregnation using solutions of oxides or sulphates in concentrated H2So4. Preferred carrier is SiO2, but Al2O3, SiC, diatomaceous earth and pumice are also mentioned. Particle sizes and bulk density data are given.
