Abstract

Saturated aliphatic, cycloaliphatic and araliphatic aldehydes are prepared by selective hydrogenation of the corresponding olefinically unsaturated aldehydes with hydrogen in the liquid phase over a palladium-containing catalyst, using a catalyst system in which the active constituents are from 2 to 90% by weight of palladium and from 10 to 98% by weight of an oxide or a salt of a rare earth metal or of a mixture of different oxides and/or salts of this type.
