This invention relates to a process for separating one or more organophosphorus ligand degradation products, one or more reaction byproducts and one or more formylester products from a reaction product fluid comprising one or more unreacted unsaturated ester reactants, a metal-organophoshorus ligand complex catalyst, optionally free organophosphorus ligand, said one or more organophosphorus ligand degradation products, said one or more reaction byproducts, said one or more products, a nonpolar solvent and a polar solvent by phase separation wherein (i) the selectivity of the nonpolar phase for the organophosphorus ligand with respect to the one or more products is expressed by a partition coefficient ratio Ef1 which is a value greater than about 2.5 (ii) the selectivity of the nonpolar phase for the organophosphorus ligand with respect to the one or more organophosphorus ligand degradation products is expressed by a partition coefficient ratio Ef2 which is a value greater than about 2.5, and (iii) the selectivity of the nonpolar phase for the organophosphorus ligand with respect to the one or more reaction byproducts is expressed by a partition coefficient ratio Ef3 which is a value greater than about 2.5.
A process for separating one or more organophosphorus ligand degradation products, one or more reaction byproducts and one or more products, said products comprising one or more formylesters and/or derivatives thereof, from a reaction product fluid comprising one or more unreacted unsaturated reactants, said unsaturated reactants comprising one or more unsaturated esters and/or derivatives thereof, a metal-organophosphorus ligand complex catalyst, optionally free organophosphorus ligand, said one or more organophosphorus ligand degradation products, said one or more reaction byproducts, said one or more products, a nonpolar solvent and a polar solvent, wherein said process comprises (1) mixing said reaction product fluid to obtain by phase separation a nonpolar phase comprising said one or more unreacted unsaturated reactants, said metal-organophosphorus ligand complex catalyst, said optionally free organophosphorus ligand and sail nonpolar solvent and a polar phase comprising said one or more organophosphorus ligand degradation products, said one or more reaction byproducts, said one or more products and said polar solvent, and (2) recovering said polar phase from said nonpolar phase;
