Abstract

Oxidic catalysts containing 20 to 25% by weight of aluminum and 40 to 50% by weight of zinc which are suitable for the production of unsaturated fatty alcohols containing 8 to 22 carbon atoms by hydrogenation of unsaturated fatty acids, fatty acid lower alkyl esters or unsaturated fatty acid glycerides are disclosed. A process for the production of the oxidic aluminum/zinc catalysts is also disclosed.
