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, CraMobTecMdOx(formula 1) where M=one or more of Mg, Ni, Sb, Ti, La, P, Ce, Fe, Nb, W, V, and Cu, each of a, b & c is 0.1 to 10 d is zero to 10 a+b+c>1.5d, and x is determined by the valence requirements of the other elements present, and wherein the reactants fed to the reaction zone contain a mole ratio of said paraffin:NH3 in the range from 2.5 to 16 and a mole ratio of said paraffin:O2 in the range from 1 to 10.
