Abstract
Provided are a hydrogenation catalyst for carbonyl groups which can produce an unsaturated alcohol by hydrogenating an unsaturated carbonyl compound with high selectivity by a simple process at low cost, a method of efficiently producing the hydrogenation catalyst, and a practical method of producing an unsaturated alcohol by using the hydrogenation catalyst. In the present invention, the hydrogenation catalyst is obtained by carrying a noble metal such as ruthenium as a catalyst component onto a carrier which is composed of an oxygen-containing gallium compound. Gallium oxyhydroxide, gallium oxide, gallium phosphate or the like can be used as the gallium compound, and a hydrogenation catalyst including the gallium compound carrier carrying 0.1 to 10% by weight of ruthenium is used suitably.
