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.

Abstract: 1523141 Oxidation catalyst STANDARD OIL CO 15 July 1975 [22 July 1974 5 Aug 1974] 29589/75 Heading B1E [Also in Division C2] An oxidation catalyst used for the preparation of unsaturated aldehydes (see Division C2) formula wherein X is Ce, Th, Pr, Nb, Ge, Y, Zr, Ru, Ga, In, Cu, La, Ta, Sb or mixtures thereof; A is alkali metal or Tl or mixture thereof; D is Ni, Co, Mg, Mn, Zn, Cd, Ca, Sr or mixture thereof, except that D is not Mn unless X is Sb; E is P; As, B, S, Al or mixture thereof; a is greater than O but less than S; b and d are 0-4 except that b is not zero if X is Ga, In, La, Nb, Ge or Ta; c, f and g are 0.1-12; and X is a positive number. The catalyst may be supported, e.g. on alumina, silica, titania, zirconia or silicon carbide. The Examples relate to silicasupported catalysts formed by mixing a silica sol with solutions of compounds of the elements to be present, evaporating and calcining.
