ABSTRACT:
Process for the separation and recovery of aldehyde product from a non-aqueous hydroformylation reaction product composition comprising the aldehyde product, a rhodium-ionically charged phosphorus ligand complex, a free ionically charged phosphorus ligand and an organic solubilizing agent for said complex and said free ligand via phase separation using added water or both added water and an added non-polar hydrocarbon compounds.
