Abstract

Un procedimiento para la separación continua de etilendiamina de su producto bruto, obtenido por reacción entre bicloruro de etileno y amoníaco, procedimiento caracterizado por el hecho de que la solución acuosa neutralizada que contiene etilendiamina, aminas superiores y cloruro sódico en suspensión, se envía continuamente a un evaporador que se mantiene a temperatura de 70 a 140ºC a presión reducida o substancialmente atmosférica, para hacer que el agua y las aminas alimentadas se evaporen completamente.
