  • 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
  • Oxo process for increasing yield of oxo alcohol
    Patent number: 5059718
    Abstract: Improved oxo process for preparing higher alcohols by hydrolyzing prior to hydrogenation a demetalled hydroformylation reaction product in the presence of an alumina catalyst having a surface area between 40 to about 60 m.sup.2 /g.
    Type: Grant

    Inventors: Vargas, Jose M., Jean A. Hanin, John C. Reisch
  • Production of ether/ether-alcohol compositions
    Patent number: 4982011
    Abstract: Ether/ether-alcohol rich compositions are produced by hydrogenating hydroformylation reaction products, separating an ether/ether-alcohol containing mixture from the hydrogenation product, and catalytically hydrogenating such mixture at 200.degree.-250.degree. C. and 30-100 atmospheres. The crude product is then reflux distilled to separate the ether/ether-alcohol rich compositions from lighter and heavier ends.

  • Ether-containing mixtures in flexible PVC
    Patent number: 4735743
    Abstract: Heavy organic by-products obtained by hydroformylating olefins and hydrogenating the crude product to obtain higher alcohols, and their steam cracked derivatives, have been found useful as viscosity modifiers and low temperature property improvers in flexible PVC compositions.
    Type: Grant

    Inventors: Jean A. Hanin, Pierre E. Verrier
  • Hydroformylation of olefins
    Patent number: 4658068
    Abstract: The higher alcohol yield of a hydroformylation process comprising catalytic hydroformylation of olefinic feedstock and hydrogenation of the crude product is improved by separating light materials and desired alcohols from the hydrogenated product, and then subjecting the remaining heavy materials to catalytic steam cracking at 260.degree.-380.degree. C. The fraction of the cracked product which is rich in alcohol/aldehyde is then separated and recycled, preferably to the hydrogenation stage.

  • Hydroformylation catalyst removal
    Patent number: 4625067
    Abstract: Cobalt values are removed from the crude product of a cobalt-catalyzed hydroformylation reaction by contacting the product with stripping gas to entrain volatile cobalt compounds, in the presence of water or aqueous acid to dissolve cobalt values not so entrained.
