Abstract

Abstract Alkyl-substituted sym-dibenzo-16-crown-5-oxyacetic acid and sym-dibenzo-16- crown-5-oxydodecanic acid were synthesized and applied as ion transport carriers in liquid and film membranes. Increasing crown-ether lipophilicity decreased acid dissociation constants and solubilities of crown-ether carboxylic acids in water but enhanced the solubility and transport ability of the carboxylic anion-K+ complex through a liquid organic ...
