Abstract
The invention deals with the separation of homogeneous catalysts from reaction mixtures with the help of organophilic nanofiltration. It is based on the object of indicating an option as to how organophilic nanofiltration can be used economically for separating off homogeneous catalysts from reaction mixtures if the separation-active material of the membrane satisfying the separation aim is not available in sufficiently large amounts or only at high cost. This object is achieved by taking into consideration a particular membrane performance indicator during the design and/or the execution of the corresponding membrane separation process.
