Study of Lithium-Extraction Systems Based on Benzo-15-Crown-5 Ether and Alkylimidazolium-Based Ionic Liquid
The extraction of lithium from aqueous solutions of LiNTf<sub>2</sub> and LiCl salts using benzo-15-crown-5 ether (B15C5) as an extractant in [C8mim][NTf<sub>2</sub>] ionic liquid was studied. The transition of the extractant into the aqueous phase and the distribution of Cl&...

| Summary: | The extraction of lithium from aqueous solutions of LiNTf<sub>2</sub> and LiCl salts using benzo-15-crown-5 ether (B15C5) as an extractant in [C8mim][NTf<sub>2</sub>] ionic liquid was studied. The transition of the extractant into the aqueous phase and the distribution of Cl<sup>−</sup> ions during lithium extraction from LiCl solutions were determined. LiNTf<sub>2</sub> complexes with B15C5 with different LiNTf<sub>2</sub>:B15C5 ratios were isolated for the first time and characterized via X-ray diffraction and IR spectroscopy. Differences in the extraction process of LiCl and LiNTf<sub>2</sub> were determined via an infrared spectroscopic study of the extraction systems. |
