Propionitrile prodn - by catalytic hydrogenation of acrylonitrile

摘要

Propionitrile is produced by hydrogenating acrylonitrile at 10-100 degrees C and at a pressure of 15-500 atm g. in the presence of 0.1-10 wt.% Pd, Rh, or Ru on carrier catalyst. The prefd. catalyst is a 0.3-1.0 wt. % Pd-on-alumina catalyst. The catalysts have a prolonged operational life throughout which propionitrile yields of >90% are obtd.
