Patent ID: 8134031

Claim:
An extraction process of a hydroformylation product composition to separate therefrom an aldehyde product and to recover a hydroformylation catalyst, the process comprising mixing a non-aqueous hydroformylation product composition comprising a mixture of formyl-substituted fatty acid triglyceride esters, a transition metal-organophosphine ligand complex wherein the organophosphine ligand is ionically charged, optionally free ionically-charged organophosphine ligand, and a polar organic solubilizing agent for said complex and said free ligand with water and an extraction solvent having low water solubility, under conditions sufficient to obtain by one or more stages of phase separation an organic phase comprising the mixture of formyl-substituted fatty acid triglyceride esters and the extraction solvent having low water solubility and an aqueous phase comprising the transition metal-organophosphine ligand complex wherein the ligand is ionically-charged, optionally free ionically-charged organophosphine ligand, the polar organic solubilizing agent, and water.
