HIGH TEMPERATURE VAPOR PHASE CATALYTIC DIMERIZATION OF ACRYLONITRILE

摘要

HIGH TEMPERATURE VAPOR PHASE CATALYTIC DIMERIZATION OF ACRYLONITRILE Acrylonitrile is dimerized to 1,4-dicyanobutenes and adiponitrile by contacting acrylonitrile in the vapor phase with a catalyst comprising activated alumina containing inorganic sulfide ion.
