    Abstract: A process of manufacturing acrylonitrile or methacrylonitrile by the catalytic reaction in the vapor phase of a paraffin selected from propane and isobutane with molecular oxygen and ammonia by catalytic contact of the reactants in a reaction zone with a catalyst, the feed composition having a mole ratio of the paraffin to ammonia in the range of from about 2.5 to 16 and a mole ratio of paraffin to oxygen in the range of from about 1.0 to 10, wherein said catalyst has the elements in the proportions indicated by the empirical formula: VSbmAaMobDdOx where A is one or more of Ti, Sn, Fe, Cr and Ga; D is one or more of Li, Mg, Ca, Sr, Ba, Co, Ni, Zn, Ge, Nb, Zr, W, Cu, Te, Ta, Se, Bi, Ce, In, As, B and Mn; m equals 0.8 to 4; a equals 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.
