Abstract
This invention relates to a process for separating one or more organophosphorus ligand degradation products, one or more reaction byproducts and one or more products from a continuously generated reaction product fluid comprising one or more unreacted reactants, 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, one or more nonpolar solvents and one or more polar solvents 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 Ef1which 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.
