1. A process for preparing alkanolamines and ethyleneamines in the liquid phase, by reacting ethylene glycol, monoethanolamine, or a combination thereof with ammonia in the presence of an amination catalyst which is obtained by reducing a catalyst precursor, wherein the preparation of the catalyst precursor comprises a step a) in which a catalyst precursor comprising one or more catalytically active components of Sn, Cu and Ni is prepared by coprecipitation or by precipitative application, and a step b) in which the catalyst precursor prepared in step a) is contacted with a soluble Re compound by post-impregnating the catalyst precursor with an impregnating solution comprising the soluble Re compound.
