摘要：
A method for making N,N′-bis(3-aminopropyl)-1,2-ethylenediamine which comprises reacting acrylonitrile and ethylenediamine in about a 2:1 molar ratio to make a N,N′-bis(cyanoethyl)-1,2-ethylenediamine reaction product and hydrogenating the reaction product, the improvement for improving the selectivity of the reactions to N,N′-bis(2-cyanoethyl)-ethylenediamine and to N,N′-bis(3-aminopropyl)-1,2-ethylenediamine which comprises reacting acrylonitrile and ethylenediamine in the presence of 2-30 wt % water, based on total reactants.
