Abstract

Carrier-bound ruthenium catalysts are used to produce alcohols by the catalytic hydrogenation of aldehydes and ketones. The problem of deactivation of the catalyst is solved by the use of a ruthenium catalyst on an oxide carrier of the series TiO2, SiO2, ZrO2, MgO, mixed oxides thereof and silicates thereof. In particular, Ru on TiO2 or SiO2 results in a long service life of the catalyst.
