FIELD: industrial organic synthesis. SUBSTANCE: ethylenediamine is obtained by interaction of dichloroethane with 20-60% aqueous ammonia solution at dichloroethane-to-ammonia molar ratio 1:(1.8-2.5), temperature 130 to 180 C, pressure 0.8 to 7.0 MPa, and vigorous stirring at 2500-3000 rpm. EFFECT: increased yield of ethylenediamine and improved its quality. 6 ex
