Method for enriching a homogeneous catalyst from a process flow

摘要

The invention relates to a method for enriching a homogenous catalyst from a process flow comprising said homogenous catalyst as a component, wherein the process flow is conducted over at least one membrane and wherein the membrane wholly or partially comprises a polymer that has planar polymer units connected to one another via a rigid link and wherein the linker is contorted, such that at least one planar polymer unit is connected to at least one second planar polymer unit via the link, in a non-co-planar arrangement. The invention furthermore relates to a method for producing tridecanal.

1. A method of concentrating a dissolved solid homogeneous catalyst from a process stream comprising the homogeneous catalyst, the method comprising:
passing the process stream over at least one membrane, wherein the membrane comprising a polymer comprising at least one planar polymer unit, connected to one another via a rigid linker, with the linker being intrinsically twisted so that at least one first planar monomer unit is joined via the linker in a noncoplanar arrangement to at least one second planar polymer unit.
