Abstract:
A process for making acrylonitrile or methacrylonitrile by the catalytic reaction in the vapor phase of a paraffin selected from propane and isobutane with 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 about 1.0 to 10 and a mole ratio of paraffin to oxygen in the range of about 1.0 to 10, wherein said catalyst is represented by the following empirical formula:Mo.sub.a V.sub.b Sb.sub.c Ga.sub.d X.sub.e O.sub.xwhereX is one or more of As, Te, Se, Nb, Ta, W, Ti, Zr, Cr, Mn, Fe, Ru, Co, Rh, Ni, Pd, Pt, B, In, Ce, Re, Ir, Ge, Sn, Bi, Y, Pr, an alkali metal, and an alkaline earth metal,a equals 1,b equals 0.0 to 0.99,c equals 0.01 to 0.9,d equals 0.01 to 0.5,e equals 0.0 to 1.0,x is determined by the oxidation state of the cations present, and wherein the catalyst is free of Te.
