Potassium transfer facilitated by monoaza-18-crown-6 across the water—1,2-dichloroethane interface

Abstract

The facilitated potassium transfer by monoaza-crown-6 (A18C6) across the water—1,2-dichloroethane interface has been investigated by cyclic voltammetry. The pH of the aqueous phase determines the nature of and the type of assisted ion transfer, i.e. proton transfer, assisted metal ion transfer or both. The stability constants of protonated A18C6 and potassium-A18C6 in 1,2-dichloroethane, and potassium-A18C6 in water, have been evaluated from the voltammetric data.
