Abstract
This invention provides an improved process for converting .alpha.,.beta.-olefinically unsaturated aldehydic or ketonic compounds into the corresponding allylic alcohol using an alcohol as a hydrogen donor. This process is conducted in the presence of a supported tetragonal zirconium oxide catalyst or supported HfO.sub.2, V.sub.2 O.sub.5, NbO.sub.5, TiO.sub.2 and Ta.sub.2 O.sub.5 catalysts.
Claims5
In a process for converting an .alpha.,.beta.-olefinically unsaturated aldehydic or ketonic compound into the corresponding allylic alcohol derivative which comprises reacting the .alpha.,.beta.-olefinically unsaturated aldehydic or ketonic compound with an alcohol in the presence of a metal oxide catalyst supported on a support;
- the improvement wherein;
- (a) the catalyst is ZrO.sub.2
- (b) the support is silica;
- and
- (c) the reaction is conducted in a liquid phase.
