    Abstract: Disclosed is a method for ammoxidizing C3 to C5 mono-olefins to a,b-mono-unsaturated acyclic nitriles having 3 to 5 carbon atoms and HCN by introducing such mono-olefins molecular oxygen and ammonia into a reaction zone into vapor phase contact with a solid ammoxidation catalyst, wherein the mol ratio of introduced molecular oxygen and ammonia to said introduced mono-olefin is at least 1.5 and 1.0, respectively, wherein said catalyst contains the elements and proportions indicated by the empirical formula: V1SbaMmNnOx where a = 0.5 to 2 M = one or more of: Sn, Ti, Fe, and Ga m = 0.05 to 3, usually at least 0.1 and at most 1 N = one or more of: W, Bi, Mo, Li, Mg, P, Zn, Mn, Te, Ge, Nb, Zr, Cr, Al, Cu, Ce, B n = 0.0 to 0.5, and wherein the preparation of the catalyst includes contacting in an aqueous dispersion a vanadium compound and an antimony compound while said vanadium is in solution.

    Abstract: A process for preparing a supported solid oxide complex catalyst using silica as support characterised in that one adds fumed silica to a mixture containing one or more active components of the catalyst; dries said mixture to form a dried first-stage mixture; adds, in solution, silica or a silica-containing compound other than fumed silica to the dried first stage mixture optionally with further fumed silica; and dries and calcines the resulting mixture is provided. The use of fumed silica produces a supported solid oxide complex catalyst of increased attrition resistance. Such catalyst is useful in the preparation of unsaturated aldehydes and acids from propylene or isobutylene by vapour phase oxidation. The use of inert or recycle gas increases the performance of such catalyst in this reaction.
