Abstract
A novel catalyst system comprising (1) a cobalt carbonyl, a hydrido cobalt carbonyl or a cobalt-containing material convertible to a cobalt carbonyl or a hydrido cobalt carbonyl, (2) a tertiary organo Group VA compound of the Periodic Table, (3) an iodine compound and (4) a ruthenium compound and to a process for selectively producing ethanol 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) a tertiary organo Group VA compound of the Periodic Table, (6) an iodine compound and (7) a ruthenium 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 ethanol.
