ABSTRACT:
Certain basic impurities, e.g., N-heterocyclic amines such as 2-methyl-4-amino-5,6-trimethylene pyrimidine are removed from adiponitrile by contact with solid acidic sorption agents, e.g., strong acid ion exchange resins before its hydrogenation to hexamethylene diamine to reduce odor and color of products prepared from the diamine.
