Abstract
The present invention relates to a method of preparing an alcohol by reducing a carboxylic acid or a derivative thereof, more particularly, a method of preparing an alcohol by a reduction reaction in the presence of a zirconium-titanium oxide catalyst. A carboxylic acid or a carboxylic acid derivative is converted into a corresponding alcohol by a reduction reaction in the presence of a zirconium-titanium oxide catalyst using an alcohol as a hydrogen source. An alcohol can be prepared in a high yield in the present invention. To be more specific, the method of the present invention can convert a higher fatty acid or a carboxylic acid derivative, which has given a corresponding alcohol in a low yield in the presence of a zirconium catalyst alone, into the corresponding alcohol in a high yield. Further, the reaction can be performed easily, and the product can be easily separated from the catalyst.
