Abstract: PROBLEM TO BE SOLVED: To provide an improved process for ammoxidation from a paraffin into an unsaturated mononitrile and corresponding monoolefin. SOLUTION: This process is to synthesize acrylonitrile or methacrylonitrile by a catalytic reaction of a paraffin selected from between propane and isobutane in the vapor phase according to a catalytic contact of a catalyst with a reactional component in a reactional zone of oxygen molecules with ammonia. The feed composition has a molar ratio of the paraffin to the ammonia within the range of about 2.5-16 and a molar ratio of the paraffin to the oxygen within the range of about 1.0-10. The catalyst contains elements in a ratio represented by the empirical formula VSbm Aa Mob Dd Ox [A is one or more kinds of Ti, Sn, Fe, Cr and Ga; D is one or more kinds of Li, Mg, Ca, Sr, Ba, Co, Ni, Zn, Ge, Nb, Zr, W, Cu, The, Ta, Se, Bi, Ce, In, As, B and Mn; (m) is 0.8-4; (a) is 0.01-2; 0

Abstract: The invention relates to the production of acrylonitrile or methacrylonitrile by catalytic reaction in paraffin steam phase selected between propane and isobutane with molecular oxygen and ammonia at catalytic contact between the reagents and the catalyst in the reaction zone. The burden composition has molar ratio of paraffin to ammonia from 2.5 to 16 and paraffin to oxygen molar ratio from 1 to 10. The elements and the proportions of the catalyst are determined by the empiric formula VSbmAaMobDdOx where A means one or more of the elements Ti, Sn, Fe, Cr and Ga; D isone or more of the elements Li, Mg, Ca, Sr, Ba, Co, Ni, Zn, Ge, Nb, Zr, W, Cu, Te, Ta, Se, Bi, Ce, In, As, B and Mn; m has the value of 0.8 to 4; a is from 0.01 to 2; 0

Abstract: Disclosed is a method of making a catalyst precursor by reacting the ion VO(O2)+ in aqueous solution with an antimony compound that contains Sb having a valence of 3. In one embodiment, the VO(O2)+ ion is made by reacting H2O2 with a vanadium compound. Also disclosed is making a catalyst by drying and calcining such precursor. When the drying is effected by spray drying a new microspheroidal catalyst is produced. The catalysts useful for ammoxidation of propane are more attrition resistant than catalysts of the same empirical formula made by prior art methods.
