Abstract

PURPOSE: To obtain the title compound selectively in a high yield industrially advantageously under mild conditions in a relatively short reaction time, by reacting ethylenediamine with glycolonitrile without using a catalyst, e.g. an organic or inorganic acid.
CONSTITUTION: One mole of ethylenediamine is reacted with 2-2.5moles of glycolonitrile in an aqueous medium at ordinary temperatures for about 1hr to give ethylenediaminediacetonitrile.
EFFECT: Easy control of equipment, waste liquor treatment, and reaction. Scarcely causing discoloration of the objective compound.
USE: Intermediate for synthesis of chelating compounds
