ABSTRACT:
Aldehydes branched at the second carbon are surprisingly hydrogenated selectively in good yield to the corresponding primary alcohols over a copper catalyst by using a hydrogen/carbon monoxide mixture having molar ratio about 2/1; simultaneously said mixture is depleted of hydrogen to a level where it can be used directly in the Oxo-hydroformylation process without further pretreatment.
