    摘要: The invention relates to a process for preparing an ethylene amine mixture, which comprises the following steps: a) crude AAN which is largely free of formaldehyde cyanohydrin (largely FACH-free) is heated at a temperature of from 50 to 150° C. to give an amino nitrile mixture comprising aminoacetonitrile (AAN) and from 5 to 70% by weight of iminodiacetonitrile (DAN), b) hydrogenation of the amino nitrile mixture obtained in step a) in the presence of a catalyst. Ethylenediamine (EDA) and/or diethylenetriamine (DETA) and also, if appropriate, further ethylene amines can be isolated from the ethylene amine mixtures obtained.

    摘要: The invention relates to a process for preparing ethylenediamine by hydrogenation of aminoacetonitrile over a catalyst, wherein the hydrogenation is carried out in a solution comprising aminoacetonitrile, water in a proportion of from 0 to 60% by weight and a solvent and the aminoacetonitrile comprised in the solution is fed into the reaction vessel at a rate which is not greater than the rate at which the aminoacetonitrile reacts with hydrogen in the hydrogenation.
