PCT No. PCT/JP96/01601 Sec. 371 Date Dec. 22, 1997 Sec. 102(e) Date Dec. 22, 1997 PCT Filed Jun. 12, 1996 PCT Pub. No. WO97/00841 PCT Pub. Date Jan. 9, 1997A method for producing an alcohol comprising the steps of continuously feeding starting materials of an alcohol; and carrying out catalytic reduction reaction of the starting materials in the presence of a hydrogenation catalyst, wherein said starting materials of an alcohol and a hydrogen gas are fed in a gaseous state or a mixture of liquid and gaseous states in a reduction reactor, and wherein said catalytic reduction reaction of the starting materials is carried out under temperature conditions, pressure conditions, and conditions of a molar ratio of hydrogen ((hydrogen molecules/(acyl groups in the starting materials)), sufficient to give an evaporation ratio of the starting materials of from 20 to 80% by weight, and wherein a ratio of VG to VL satisfies the following relationship in the reduction reactor: 100</=VG/VL</=10000, wherein "VG" stands for the superficial velocity at a gas phase portion of a mixture of the starting materials of an alcohol fed and hydrogen gas; and "VL" stands for the superficial velocity at a liquid phase portion of the mixture. |
