ABSTRACT:
Ethanol and/or acetaldehyde are prepared in good yield by contacting methanol, hydrogen and carbon monoxide with a catalyst system comprising a cobalt-containing compound and a promoter in the presence of an inert oxygenated solvent at a temperature of from about 50.degree. C. to about 350.degree. C. and a pressure of at least 500 psig or greater. The combination of cobalt-containing compound and promoter may be (a) a cobalt-containing compound with an organo-sulphur compound, (b) an iodide-containing cobalt compound with a nitrogen-containing compound as promoter, and (c) a cobalt-containing compound with 1,1'-bis(diphenylphosphino)ferrocene.
