| Abstract: | To provide insight into the influence of geminal group (R) variation in sym-(R)dibenzo-16-crown-6-oxyacetic acids upon their selectivity in alkali metal cation separations by solvent extraction and liquid membrane transport, studies have been conducted for R=hydrogen and decyl in homogeneous solutions by 1H NMR spectroscopy and titration calorimetry and in the solid state. |
