Abstract: Acrylonitrile and methacrylonitrile is prepd. by ammoxidation of propylene and isobutyrene resp., using improved catalyst which can be represents as JaQ6ZcFedDeMo12Ox, where J is an alkali metal, Tl and Ag, Q is Co, Ni, Zn, Cd, Be, Mg, Ca, Sr, Ba and Ra, Z represents Ge+Sb, Cu+W, Cu+Sn, Ce+W, Pr+Mn, Sn+Mn, Mn+W, W+Sb, Cr+Sn, W+Sn, Ge+Sn, Sb+Sn, W+P, Sb+P, Cr+Cu, Mn+Cu, Sb+Cu and Mn+P, D is Bi or Te, a = 0.03-0.05, b = 4-10, C = 0.5-7, d = 0.5-5, e - 0.5-5, and x is as necessary for balance. For example, MnWo.5 (Ko.1Ni2.5Co4.5 Fe2BiMo12Ox) supported on 20% SiO2 gave acrylonitrile with 86.4% selectivity and 68.5% conversion per pass at 420≦̸C.
