Abstract
A process for producing methanol from synthesis gas in the liquid phase is disclosed, which comprises reacting CO with H.sub.2 in the presence of a catalytic system constituted by one or more copper compound(s) and one or more alkali metal and/or alkali-earth metal alkoxide(s), in the presence of one or more solvent(s), the basic features of which are in that to the reaction methanol and one or more alkyl formate(s) are added, with the process being carried out with a concentration of the catalytic system in the solution constituted by the solvents and the same catalytic system, which is comprised within the range of from 0.001 to 1 molar for the compound(s) of copper, and is comprised within the range of from 0.01 to 5 molar for the alkali metal and/or alkali-earth metal alkoxide(s), and at a temperature higher than 40.degree. C., and lower than 200.degree. C.
