- Аннотация: The extraction of Li, Na and K trichloroacetates by benzo-15-crown-5 ether and its lipophilic analog in chloroform has been studied. Extraction isotherms were obtained and the transition of extractants into the equilibrium aqueous phase was determined. The metal: crown ether ratios in the extracted compounds were determined by the slope analysis method. The thermodynamic extraction parameters of Li, Na and K trichloroacetates in systems with benzo-15-crown-5 ether (B15C5) and 3-tert-pentylbenzo-15-crown-5 ether (tPB15C5) were determined. The complexes [Li3(B15C5)(TCA)3], [Na(B15C5)(TCA)] and [K(B15C5)2](DCA)·H2O were isolated in crystalline form and characterized by IR spectroscopy and X-ray diffraction.
