    Abstract: Disclosed is a process for making an alpha , beta -unsaturated mononitrile by the catalytic reaction of a paraffin containing 3-5 carbon atoms with molecular oxygen and ammonia by catalytic contact of the foregoing reactants in a reaction zone with a metal oxide catalyst containing the elements indicated by the empirical formula, Vv Aa DdSnm Sbn CucOx (formula 1> in the relative atomic proportions indicated by the subscripts, where A is selected from Te and Bi D is one or more optional elements selected from Mo, W, Ti, Ge, Ce, La, Cr, Mn, Mg, Ca, Co, Ni, Fe, Nb, Ta, Ag, Zn, Cd, B, P, Na, K and Cs, and a is 0.001 to 30 d is zero to 30 c is 0.001 to 30 m is 0.1 to 60 n is 0.1 to 60 n/v is > 12 and /= v + a + c + d, and x is determined by the valence requirements of the elements present, and wherein the reactants fed to the reaction zone contain a mole ratio of said paraffin:NH3 in the range from 2 to 16 and a mole ratio of said paraffin:O2 in the range from 1 to 10.

    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.
