Abstract
A process for selectively producing acetaldehyde which comprises introducing into a reaction zone (1) methanol, (2) hydrogen, (3) carbon monoxide, (4) a cobalt carbonyl, a hydrido cobalt carbonyl or a cobalt-containing material convertible to a cobalt carbonyl or a hydrido cobalt carbonyl, (5) an arsenic or antimony base ligand and (6) an iodine compound and then subjecting the contents of said reaction zone to an elevated temperature and an elevated pressure for a time sufficient to convert methanol to acetaldehyde.
