Process for the separation of catalysts from metal complexes from a reaction mixture obtained from a telomerization, characterized in that the metal complex catalyst separates into at least one membrane that is permeable for molecules with a molar mass of up to 1000 g / mol, wherein the free ligand present in the reaction mixture, chosen from an organophosphorus or carbine ligand, is separated in the membrane and returned to telomerization, and in which the membrane is chosen from membranes which, in quality With an active layer in the separation, they have a stable nanofiltration polymer layer against alkalis and solvents based on polyimides (PI), aromatic polyamides (PA), polyamidimides (PAI), polybenzimidazoles, acrylonitrile / glycidyl methacrylate (PANGMA) , polybenzimidazolones, polyacrylonitrile (PAN), polyaryl ether sulfones, polyesters, polyether ether ketones (PEEK), polycarbonates (PC), polytetrafluoroethylene, polib Encimidazole (PBI), poly (vinylidene fluoride) (PVDF), polypropylene (PP), polydimethylsiloxane (PDMS), or whose active layer in the separation consists of polymers with an intrinsic microporosity (PIM), or whose active layer in the separation is constituted through a hydrophobic ceramic membrane. |
