Partition Coefficients at Infinite Dilution from Flory-Huggins Theory

Abstract

An expression relating partition coefficients at infinite dilution to Flory-Huggins interaction parameters has been derived. The equation has been successfully applied to the partitioning of alcohols between water and cellulose acetate. The solvent-solute interaction parameter has a dominant effect on partition coefficients. For the systems studied, solvent-polymer interactions appear to be negligible.
