Abstract
This invention relates to a process for the catalytic hydrolysis of an .alpha.-aminonitrile in the heterogeneous phase, and to polymeric resins having a catalytic activity for carrying out the present process. The process according to this invention is characterized in that said .alpha.-aminonitrile or one of the salts thereof is reacted in an aqueous medium, in the heterogeneous phase and in the presence of hydroxide ions on a polymeric resin which contains side chains carrying a carbonyl group, and which is insoluble in the aqueous basic medium.
