摘要： The present invention relates to an improved catalyst on the basis of a shaped catalyst body for hydrogenating carbonyl groups in organic compounds under the effect of acids and water, characterized in that the shaped catalyst body contains copper in an amount of 17.5 to 34.5 wt. %, relative to the shaped catalyst body and the copper is present in the shaped catalyst body to at least 70% in the form of a copper spinel CuAl2O4. The invention also relates to the production of the catalyst an to the use of same in the hydrogenation of carbonyl groups in organic compounds in the presence of acids and/or water.

摘要： The present invention relates to an improved chromium-free Cu—Al catalyst for the hydrogenation of carbonyl groups in organic compounds, characterized in that the catalyst contains zirconium in a proportion of 0.5 to 30.0 wt. %. The invention also relates to the production of the catalyst and to the use of same in the hydrogenation of carbonyl groups in organic compounds.
