PROBLEM TO BE SOLVED: To provide a method of producing a high-purity unsaturated alcohol in good yield by suppressing side reactions caused by a double bond in the unsaturated alcohol when the unsaturation is reduced. SOLUTION: An unsaturated aldehyde, an unsaturated fatty acid or an unsaturated fatty acid ester is hydrogenated using a zinc-chrome-based or a zinc- chromium-aluminum-based compound metal oxide catalyst to produce the unsaturated alcohol. In the process, the compound metal oxide catalyst having a content of copper contained in the compound metal oxide catalyst of <=100 ppm expressed in terms of the metal and a content of nickel contained in the compound metal oxide catalyst of <=200 ppm expressed in terms of the metal is used. |
