Abstract (en)

[origin: WO2014183952A1] The invention relates to a method for separating a homogeneous catalyst out of a reaction mixture by means of at least one membrane separation unit, in which method: the reaction mixture coming from a reaction zone and containing the homogeneous catalyst is applied as a feed to the membrane separation unit; the homogeneous catalyst is depleted in the permeate of the membrane separation unit and enriched in the retentate of the membrane separation unit; and the retentate of the membrane separation unit is recirculated into the reaction zone. The invention addresses the problem of specifying a method for separating homogeneous catalyst out of reaction mixtures that simplifies the feeding of fresh catalyst into the reaction zone and avoids disruptions to the hydrodynamics within the reaction zone when the volumetric flow of the reaction mixture output from the reaction zone varies. This problem is solved in that both the retentate volumetric flow of the membrane separation unit and the retention of the membrane separation unit are kept constant by regulation.
