FIELD: chemistry.
SUBSTANCE: invention relates to a method of producing a mixture of ethylene amines. According to the disclosed method, a mixture of amino nitriles containing at least 30 w t% amino acetonitrile and at least 5 wt % imino diacetonitrile is hydrogenated in the presence of a Raney catalyst. Ethylene diamine and diethylene triamine and, optionally, further ethylene amines, can be separated from the obtained mixture of ethylene amines.
EFFECT: method enables to obtain a mixture of ethylene amines with high conversion and/or selectivity.
