  • Hydroformylation of olefins
    Patent number: 4148830
    Abstract: A hydroformylation process whereby rhodium complex catalyst and excess triorganophorus ligand are employed, under mild conditions of temperature and pressure, to produce aldehydic products rich in the normal isomer thereof, the improvement representing the introduction and/or recycling of the rhodium complex in active form and soluble in a complex mixture of high boiling liquid condensation products rich in hydroxylic compounds.
    Type: Grant
    Filed: May 5, 1976
    Date of Patent: April 10, 1979
    Assignee: Union Carbide Corporation
    Inventors: Roy L. Pruett, James A. Smith
