PURPOSE:To obtain a higher alcohol and a dihydric alcohol in a simple process without causing environmental pollution by using a readily preparable copper oxide-based compound as a catalyst and carrying out hydrogenation treatment of an organic carboxylic acid ester compound in the presence of hydrogen. CONSTITUTION:A compound expressed by the formula [M is element of the fourth to sixth periods in group III of the periodic table; (x+y) is 1; (x/y) is 0-10; (z) is 6-8] is used as a catalyst and an organic carboxylic acid ester compound is hydrogenated in the presence of hydrogen in an amount of 2-100 equiv., preferably 5-30 equiv. based on 1 equiv. ester group in the aforementioned organic carboxylic acid ester compound at 130-300 deg.C, preferably 180-280 deg.C temperature under 1-300kg/cm<2>, preferably 5-280kg/cm<2> pressure to afford the corresponding higher alcohol and dihydric alcohol. The above-mentioned catalyst is used in an amount within the range of 0.01-30wt.%, preferably 0.1-20wt.% based on the raw material compound and readily separated from the reaction mixture by filtration, etc., after completing the reaction. |
