An improved process is described for synthetically converting methanol to ethanol in which a mixture of methanol and cobalt catalyst is pre-pressurized with an atmosphere of carbon monoxide at room temperature and at a pressure of about 10 to 1000 psi gauge, in a suitable pressure vessel. A gaseous mixture of carbon monoxide/hydrogen, in the stoichiometric 1:2 molar ratio, is then introduced to react with the methanol/cobalt catalyst mixture and the temperature is raised to about 175 DEG to 240 DEG C. at a pressure of about 3000-6000 psig. The improved process leads to higher selectivities of ethanol formation with lowered amounts of by-products.
