Abstract:
A process for the production of unsaturated nitrites from the corresponding olefins which comprises reacting the olefin with a molecular oxygen containing gas and ammonia in the vapor phase at a temperature from about 200.degree. C. to 550.degree. C. in the presence of a catalyst system comprising a catalyst composition having the empirical formula:Bi.sub.a Mo.sub.b V.sub.c Sb.sub.d Nb.sub.e Ag.sub.f A.sub.g B.sub.h O.sub.x,whereinA is one or more elements selected groups VB, VIB, VIIB or VIII of the periodic table;B is at least one alkali or alkaline earth metal promoter selected from groups IA or IIA of the periodic table;a=0.01 to 12;b=0.01 to 12;c=0.01 to 2;d=0.01 to 10;e=0.01 to 1;f=0.0001 to 2;g=0 to 2;h=0 to 1; andx=the number of oxygen atoms required to satisfy the valency requirements of the elements present.
