Enantioselective extraction of phenylsuccinic acid in aqueous two-phase systems based on acetone and β-cyclodextrin derivative: Modeling and optimization through response surface methodology.
To optimize enantioselective partitioning conditions of PSA in acetone/SBE-β-CD ATPS, three factors (PSA concentration, pH, and equilibrium temperature) were analyzed by using central composite design in response surface methodology.
