A catalyst particularly suitable for selectively producing aldehydes, particularly acetaldehyde, which comprises (1) cobalt, (2) iodine and (3) a ligand containing atoms from Group VB of the Periodic Table separated by a sterically constrained carbon-carbon bonding.

Catalyst suitable for preparing aldehydes

A process for selectively producing aldehydes, particularly acetaldehyde, which comprises introducing into a reaction zone (1) methanol, (2) carbon monoxide, (3) hydrogen, (4) cobalt, (5) iodine and (6) a ligand containing atoms from Group VB of the Periodic Table separated by a sterically constrained carbon-carbon bond 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 said aldehydes.

Process for preparing aldehydes

A process for selectively producing aldehydes, particularly acetaldehyde, which comprises introducing into a reaction zone (1) methanol, (2) carbon monoxide, (3) hydrogen, (4) cobalt, (5) iodine and (6) a specific phosphorus-containing ligand 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 said aldehydes.

Process for producing aldehydes

A process for selectively producing alcohols, particularly ethanol, which comprises introducing into a reaction zone (1) methanol, (2) carbon monoxide, (3) hydrogen, (4) cobalt, (5) iodine, (6) ruthenium and (7) a ligand containing atoms from Group VA of the Periodic Table separated by a sterically constrained carbon-carbon bond, 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 said ethanol.
