Abstract
This invention relates to a process for producing .alpha., .beta.-unsaturated alcohol, which uses unsaturated aldehyde as a starting material, and in which only the aldehyde group in the unsaturated aldehyde is selectively hydrogenated by hydrogen transfer reaction, while the carbon-carbon double bond is left as it is. The method is characterized by using a catalyst which contains at least one oxide selected from the group consisting of oxides of yttrium, lanthanum, praseodymium, neodymium and samarium, as a main active ingredient. The catalysts exhibit high activity and selectivity, as well as a long life span.
