Verfahren zur Ammoxydierung von Olefine |
摘要 |
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. |
