In a process for selectively producing ethanol from the reaction of methanol, hydrogen and carbon monoxide at a pressure of from 1,000 psig to 10,000 psig and a H2:CO mole ratio of from 1:10 to 10:1 and wherein the reaction is catalyzed by a catalyst system consisting essentially of cobalt and iodid

In a process for selectively producing ethanol from the reaction of methanol, hydrogen and carbon monoxide at a pressure of from 1,000 psig to 10,000 psig and a H2:CO mole ratio of from 1:10 to 10:1 and wherein the reaction is catalyzed by a catalyst system consisting essentially of cobalt and iodide ion, the improvement consisting of carrying out the reaction at a temperature of from greater than 180°C. to 220°C. in the presence of a substantially inert solvent from the group consisting of dioxane, toluene, tetrahydrofurane, the dimethyl ether of tetraethylene glycol and 1,2-dimethoxybenzene at an iodide to cobalt mole ratio of 0.1:1 to 4:1 and wherein the volume ratio concentration of said inert solvent to methanol is from 0.5:1 to 100:1.
