  • Minimizing cobalt catalyst loss in the production of alcohols by hydroformylation of olefins
    Patent number: 5130107
    Abstract: Cobalt is recovered from the oil/water mixed reaction product of oxonation by increasing the carbon dioxide level in the reaction product and adjusting the temperature to enhance the carbon dioxide level in the oil water phase to promote the formation of cobalt carbonate which is allowed to settle and may be removed and/or recycled increasing cobalt utilization and reducing environmental problems.
    Type: Grant
    Filed: December 21, 1990
    Date of Patent: July 14, 1992
    Assignee: Exxon Chemical Patents Inc.
    Inventors: Nicolaas A. De Munck, Mattheus D. Olijve, Raf Caers, Arie Van Vliet, Jean A. A. Hanin, Eddy Van Driessche
  • Cobalt hydroformylation catalyst recovery in the production of alcohols
    Patent number: 5091599
    Abstract: Cobalt is recovered from the oil/water mixed reaction product of an oxonation reaction by converting the cobalt in the oil/water product to carbonyls and absorption of the carbonyls in the residue obtained from the upgrading of the heavy fraction of a hydroformylation reaction.
