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.
Claims21
A process for producing an unsaturated alcohol from an unsaturated aldehyde by a hydrogen transfer reaction with an alcohol, comprising the step of reacting an unsaturated aldehyde with a primary or secondary alcohol in the presence of a hydrogen transfer catalyst consisting of an oxide selected from the group consisting of oxides of Y, La, Pr, Nd, Sm and mixtures thereof.
A process for producing an unsaturated alcohol from an unsaturated aldehyde by a hydrogen transfer reaction with an alcohol, comprising the step of reacting an unsaturated aldehyde with a primary or secondary alcohol in the presence of a hydrogen transfer catalyst consisting of yttrium oxide, samarium oxide or mixtures thereof as the main active ingredient and a second oxide selected from the group consisting of oxides Ca, Sr, Ba, Mn, Cr, Fe, Co, Ni, Cu, Zn, Zr, Ag, Cd, Ce, Pb, Bi, B, V, Sn and mixtures thereof.
