PURPOSE:To obtain the titled compound such as methanol, ethylene glycol, methyl formate, etc., in high yield, even at a low temperature, by reacting CO with H2 in liquid phase using a catalyst comprising a combination of a copper compound other than copper oxide and an alkali metal alkoxide. CONSTITUTION:The objective compound such as methanol, ethylene glycol, etc. is prepared by reacting CO with H2 at 40-185 deg.C under a pressure of 20- 150kg/cm<2> using a catalyst comprising a combination of (a) a copper compound other than copper oxide and (b) an alkali metal alkoxide and if necessary an alkali metal carboxylate. The molar ratio of alkali metal alkoxide/copper compound is pref. 3-50 to increase the amount of the product. The catalyst is prepared by compounding 0.0001-10mol of the copper compound and 0.001-10mol of the alkali metal alkoxide to 1l of the reaction medium. EFFECT:The removal of the reaction heat and the separation of the product can be carried out easily, and the circulation of a large amount of unreacted gas is not necessary. |
