POLYMERIZATION INHIBITORS FOR THE CATALYTIC HYDRATION OF ACRYLONITRILE

摘要

In the catalytic hydration of acrylonitrile to acrylamide, polymer formation is reduced or prevented by maintaining in the acrylonitrile solution a small but effective amount of cupferron, a nitrosophenol or a trialkylamine having alkyl groups of one to six carbon atoms where not more than two alkyl groups are methyl.
