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).
Cette invention se rapporte à un procédé permettant d'extraire d'un liquide organique un complexe ligand phosphite/métal des groupes 8 à 10, consistant (1) à mettre en contact le liquide organique avec un support auquel est fixé un ligand organophosphine et à séparer le mélange organique qui est pauvre en complexe ligand phosphite/métal des groupes 8 à 10, (2) à mettre en contact le support chargé ainsi obtenu avec un solvant organique et du monoxyde de carbone, et à séparer le solvant organique ainsi obtenu qui est riche en complexe ligand phosphite/métal des groupes 8 à 10, et enfin (3) à réutiliser dans l'étape (1) le support obtenu à l'étape (2).
