  • Continuous hydroformylation process for producing an aldehyde
    Patent number: 7102033
    Abstract: A continuous hydroformylation process for producing an aldehyde comprising 1) reacting an olefinically unsaturated compound, carbon monoxide and hydrogen in the presence of a rhodium-organobisphosphite complex catalyst at a partial pressure of carbon monoxide and hydrogen, and 2) exposing a mixture comprising at least a portion of the catalyst of 1) to a gaseous mixture comprising hydrogen at a pressure that is greater than the partial pressure of carbon monoxide and hydrogen during the reaction.
    Type: Grant
    Filed: April 11, 2002
    Date of Patent: September 5, 2006
    Assignee: DSM IP Assets B.V.

  • Continuous hydroformylation process
    Patent number: 7087797
    Abstract: A continuous hydroformylation process for forming an aldehyde comprising 1) reacting an olefinically unsaturated compound containing from 2 to 30 carbon atoms with carbon monoxide and hydrogen in the presence of a rhodium-bisphosphite ligand complex catalyst and 2) distilling a mixture comprising at least a part of the catalyst of 1), wherein the distilling is performed in the substantial absence of molecular hydrogen.
