Abstract: Olefins such as propylene and isobutylene are converted to the corresponding unsaturated nitriles, acrylonitrile, and methacrylonitrile, respectively, by reacting a mixture of the olefin, ammonia, and molecular oxygen-containing gas in the presence of a catalyst containing the oxides of bismuth, molybdenum, iron, nickel and magnesium, at least one element selected from the group comprising potassium and cesium, and optionally one element selected from the group comprising cobalt, phosphorus, manganese, tellurium, sodium, cerium, chromium, antimony and tungsten wherein the sum of cesium and potassium is at least 0.1 to 0.4.

Abstract: A process for the substantial reduction or complete elimination of ammonium sulfate generated during the production of acrylonitrile by the direct ammoxidation of propylene/propane, ammonia and an oxygen containing gas (e.g. air) over a fluid bed catalyst wherein the improvement comprises introducing methanol into said reactor in the upper portion of the reactor at a location where the methanol reacts with at least a portion if not substantially all of the excess ammonia without affecting the acrylonitrile yield. Preferably, methanol is introduced into the reactor at below its coking temperature. In particular, when an oxygen lean fluid bed catalyst is utilized, an additional oxygen containing gas is introduced into the reaction at a distance between about 8 to 14 inches from the methanol feed location.

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.
