VERFAHREN ZUR ABTRENNUNG EINER GRUPPE VON 8-10-METALL-PHOSPHITE-LIGARDEN-KOMPLEXEN AUS EINER ORGANISCHEN FLÜSSIGKEIT

摘要

Process to separate a group 8-10 metal/phosphite ligand complex from an organic liquid mixture, wherein the following steps are performed (1) contacting the organic liquid with a support having bonded thereto an organophosphine ligand and separating the organic mixture which is poor in group 8-10 metal/phosphite ligand complex, (2) contacting the thus obtained loaded support with an organic solvent and carbon monoxide and separating the thus obtained organic solvent rich in group 8-10 metal-phosphite ligand complex, and (3) reusing the support obtained in step (2) in step (1).
