The present invention relates to a process for preparing alkanolamines and ethyleneamines in the liquid phase, by reacting ethylene glycol and/or monoethanolamine 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, and a step b) in which the catalyst precursor prepared in step a) is contacted with a soluble Re compound.

Method for the production of ethyleneamines

The present invention relates to a hydroamination catalyst comprising boron beta zeolites, wherein the hydroamination catalyst is doped with lithium, and also a process for producing it. The present patent application further relates to a process for preparing amines by reaction of ammonia or primary or secondary amines with olefins at elevated temperatures and pressures in the presence of the hydroamination catalyst of the invention.
