Homogeneous catalyst recovery

A process for recovering a spent homogeneous catalyst from a reaction mixture comprises: (1) contacting the mixture with a resin bearing a non-ionic heterocyclic electron donor residue; (2) filtering off the resin after step (1); (3) freeing the homogeneous catalyst complex from the resin obtained i...

Zusammenfassung:	A process for recovering a spent homogeneous catalyst from a reaction mixture comprises: (1) contacting the mixture with a resin bearing a non-ionic heterocyclic electron donor residue; (2) filtering off the resin after step (1); (3) freeing the homogeneous catalyst complex from the resin obtained in (2) by displacement with a suitable ligand; and (4) recovering the homogeneous catalyst from step (3) in its active form.
