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 TiO , SiO , ZrO , MgO, mixed oxides thereof and silicates thereof. In particular, Ru on TiO or SiO results in a long service life of the catalyst.
