ABSTRACT:
A process for the production of ethanol from the cobalt-catalyzed, iodide-promoted reaction of methanol, hydrogen and carbon monoxide, attaining selectivity to ethanol heretofore unachievable at high methanol conversion, wherein the reaction is carried out in an inert solvent, at a temperature of from greater than 180.degree. C. to 220.degree. C. with an iodide to cobalt mole ratio of from 0.1:1 to 4:1.
