Disclosed is a method for producing ethyleneamines, in which ethylene oxide (EO) is continuously reacted with ammonia on an inorganic ion exchanger as a heterogeneous catalyst in anhydrous conditions in a first reaction stage, the obtained reaction product containing monoethanolamine (MEOA), diethanolamine (DEOA), and triethanolamine (TEOA) at a weight ratio MEOA: DEOA: TEOA = 80 - 94: 5.9 - 15: 0.1 - 5, and the reaction product is then continuously reacted with ammonia in the presence of hydrogen and a heterogeneous hydrogenation catalyst in a second reaction stage. |
