Abstract: A process for the manufacture of ethyleneamines and ethanolamines, comprising the steps of (i) converting a glycolaldehyde derivative of formula (II), in which R2, R3 are—the same or different—hydrogen, alkyl, such as C1-6-alkyl, or cycloalkyl such as Cs-e-cycloalkyl; and an animating agent of formula (III); in which R1 is hydrogen (H), alkyl, such as C1-6-alkyl, or cycloalkyl such as C3-6-cycloalkyl, in the gas or liquid phase; (ii) feeding the reaction products obtained in step (i) into a hydrogenation reactor, where the reaction products are converted with hydrogen in the presence of a hydrogenation catalyst.

Abstract: A process for preparing an amine by reacting an aldehyde and/or ketone with a nitrogen compound selected from the group consisting of ammonia and primary and secondary amines, and subsequent hydrogenation of the resulting reaction product in the liquid phase and in the presence of hydrogen and a heterogeneous copper oxide hydrogenation catalyst at a temperature of 20 to 230° C., wherein the aldehyde and/or ketone is reacted with the nitrogen compound either together with the hydrogenation in the liquid phase and in the presence of the hydrogen and of the catalyst (alternative 1) or in a step preceding the hydrogenation (alternative 2), and wherein the catalytically active composition of the catalyst, prior to reduction thereof with hydrogen, comprises at least 24% by weight of oxygen compounds of copper, calculated as Cu.
