Zusammenfassung:	CSL-P-3645 Disclosed is a process for making an a , .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 CUc0x (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 < 100 m + n is > 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:02 in the range from 1 to 10.
