A Convenient Method for the Synthesis of Bis[2-(2-carboxymethylphenoxy)ethyl] Ether and Bis[2-(2-carboxyphenoxy)ethyl] Ether and their Application for Transport of Alkali Metal Cations Across a Supported Liquid Membrane
Abstract
The non-cyclic carboxylic ionophores bis[2-(2-carboxymethylphenoxy)ethyl] ether (I) and bis[2-(2-carboxyphenoxy)ethyl] ether (II) have been synthesized and used as ionophores; ionophore I exhibits K+ selectivity.
