Macrocyclic Derivatives of Resorcinol and 1,3-Dihydroxynaphthalene. New Lithium and Sodium Selective Ionizable Chromogenic Reagents

Wagner-Wysiecka E.

Polish Journal of Chemistry

2001

Vol. 75, nr 10

1457-1463

The synthesis of ionizable chromoionophores, derivatives of resorcinol and dihydroxynaphthalene has been described. Acid-base properties of these compounds were studied in a mixed, water containing solvent system. Complexation of metal cations was investigated. Selectivity for lithium and sodium ions for 18-membered and 21-membered crown ethers, respectively, was found.
