Abstract

A process for the preparation of saturated alcohols from aldehydes is disclosed. The hydrogenation of saturated and unsaturated aldehydes to alcohols can be carried out over catalysts containing cooper and nickel. In the present process, the selectivity of the alcohol preparation is further improved by a combination of an alkaline copper catalyst and a nickel-containing catalyst whose carrier material has acidic centers of a certain acid strength H.sub.o.
