ABSTRACT:
Adiponitrile is separated from impurities of boiling point close to that of adiponitrile, especially 5-cyanovaleric acid and 2-cyanocyclopenten-(1)-ylamine, by reacting the impurities with a primary or secondary amine to give compounds of higher boiling point and then fractionally distilling to separate the adiponitrile.
