ABSTRACT:
A process for the production of acetaldehyde from the cobalt-catalyzed, iodide-promoted reaction of methanol, hydrogen and carbon monoxide, attaining (a) selectivity to acetaldehyde heretofore unachievable and (b) high methanol conversion, wherein the reaction is carried out in an inert solvent at a temperature of from 100.degree. C. to 180.degree. C. with an iodide to cobalt mole ratio of from 2:1 to 100:1.
