Abstract

A process for reducing .alpha.,.beta.-ethylenic aldehydes to the corresponding .alpha.,.beta.-ethylenic primary alcohols by hydrogen in the presence of a platinum-containing catalyst which has been pre-reduced in hydrogen at a temperature of at least about 50.degree. C. The process is highly selective in reducing the carbonyl group of the aldehyde in preference to the ethylenic unsaturation and said pre-reduced catalyst can be re-used in a series of aldehyde reductions without substantial loss in activity.
