Abstract:
The invention relates to a process for preparing an ethylene amine mixture, which comprises hydrogenating an amino nitrile mixture comprising at least 30% by weight of aminoacetonitrile (AAN) and at least 5% by weight of iminodiacetonitrile (IDAN) in the presence of a catalyst. Ethylenediamine (EDA) and/or diethylenetriamine (DETA) and, if appropriate, further ethylene amines can be isolated from the ethylene amine mixtures obtained.
