Abstract: In a process for the catalytic hydrogenation of a polymethylolalkanal or a monomethylolalkanal of the formula (I) where R may be identical or different and are each a substituted or unsubstituted aliphatic hydrocarbon having from 1 to 22 carbon atoms, an aryl or arylalkyl group having from 6 to 22 carbon atoms or a methylol group, in the presence of a copper-containing catalyst, the hydrogenation feed comprising the polymethylolalkanal or monomethylolalkanal has a total content of metal ions of groups 3 to 14 of the Periodic Table of the Element of up to 5 ppm.

Abstract: A method for regenerating catalyzers which contain copper as an active component and which were used in hydrogenation or in aminating hydrogenation of carbonyl compounds or in the amination of alcohols. Said method consists in treating the catalyzers with an acid.
