Abstract
Precise conductance measurements are reported for sodium, potassium, and cesium salts in methanol and acetonitrile solutions containing cyclic polyethers dibenzo-18-crown-6 and dicyclohexyl-18-crown-6. Decreases in equivalent conductance caused by the addition of a cyclic polyether to solutions of constant ionic strength were analyzed by nonlinear least squares to give association constants and equivalent conductances of the cation-polyether complex. The selectivity observed for the complexing is a function not only of ionic size but also of solvent.
