Abstract

The present invention relates to a process for the preparation of iron-doped ruthenium catalysts supported on carbon, and their use for the selective liquid phase hydrogenation of carbonyl compounds to give the corresponding alcohols, in particular for the hydrogenation of citral to give geraniol or nerol or of citronellal to give citronellol.
