Abstract

Preparing ethanolamines/ethyleneamines in the presence of an amination catalyst prepared by reducing a calcined catalyst precursor containing one or more metals of groups 8, 9, 10 and/or 11 and low basicity achieved by: a) coprecipitating catalyst precursor and active composition additionally contains alkali metals or alkaline earth metals; b) the catalyst precursor is prepared by impregnating a support material or precipitative application onto a support material containing alkali metals, Be, Ca, Ba, Sr, hydrotalcite, chrysotile or sepiolite; c) the catalyst precursor is prepared by impregnating a support material or precipitative application onto a support material and the active composition of the catalyst support contains one or more of alkali metals and alkaline earth metals; d) the catalyst precursor is calcined at temperatures of 600° C. or more; or e) the catalyst precursor is prepared by a combination of a) and d), b) and d), or c) and d).
