    Abstract: The invention relates to a method for producing an ethyleneamine mixture, comprising the following steps: a) untreated AAN, which is substantially devoid of formaldehyde cyanohydrin (FACH), is heated to a temperature of between 50 and 150°C to obtain an aminonitrile mixture containing amino acetonitrile (AAN) and between 5 and 70 % by weight of iminodiacetonitrile (IDAN); b) the aminonitrile mixture obtained in step a) is hydrogenated in the presence of a catalyst. Ethylenediamine (EDA) and/or diethylenetriamine (DETA) and optionally other ethyleneamines can be isolated from the ethyleneamine mixtures thus obtained.
