CATALYSTS FOR PREPARATION OF UNSATURATED NITRILES BY AMMOXIDATION

摘要

Catalysts for the ammoxidn. of propylene or isobutylene to unsatd. acrylonitrile or metacrylonitrile consisted of oxides of Sb, Sn, W, and K, with tha addn. of Cu, Co, or Fe. In the ammoxidn. of propylene(I) in the presense of a 4:2:0.25:0.5:0.05 Sb-Sn-Cu-K catalyst, 68% of I was converted into acrylonitrile and 11.2% into CO2 and CO.
