The hydrogenation catalyst for the carbonyl group where the precious metal supports on the gallium compound substrate which is chosen from the hydrogenation catalyst, and its production manner,

摘要

The hydrogenation catalyst for carbonyl groups that can be economically, to produce an unsaturated alcohol by hydrogenating the unsaturated carbonyl compounds in high selectivity by a simple process, and the process for efficiently producing the present invention, and I to provide a process for the production of practical unsaturated alcohols to use the hydrogenation catalyst. In the present invention, constitute a catalyst for hydrogenation with a noble metal such as ruthenium as a catalyst component on a support comprising a gallium compound containing oxygen. The gallium compound, a catalyst for hydrogenation which can be iodine gallium oxyhydroxide, gallium oxide, and gallium phosphate, etc., is supported ruthenium of 0.1 to 10% by weight gallium compound on a support these preferred I used to.
