<p>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 DEG 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.</p> |
