ABSTRACT:
A method for separating a noble metal catalyst from a crude reaction product of a noble metal-catalyzed hydroformylation reaction which comprises: (a) contacting the crude reaction product under perstraction conditions with a membrane capable of allowing a substantial portion of unreacted olefin feed and hydroformylation reaction product to pass therethrough as permeate while retaining a substantial portion of the catalyst as retentate; (b) removing the permeate by sweeping it away from the membrane by means of a sweep stream which is the same as the olefin feed used in the hydroformylation reaction; and (c) retaining the catalyst as retentate.
