“…The decrease in distribution ratios following an increase in the IL fraction in the organic phase (Figure ) might be attributed to the effect of the medium, as in the case of molecular solvents. For heterocyclic acid diamides, a decrease in the extraction efficiency is observed when less polar solvents are utilized. ,,, However, in the case of ionic liquids, we observe the opposite pattern: the values of the distribution ratio are higher for pure ionic liquids compared to the molecular solvent F-3 (dielectric constant typically around 10 for ionic liquids). Therefore, we cannot use the dielectric constant as a parameter for evaluating the extraction capabilities of our system.…”

“…18 Polar-fluorinated organic compounds are considered as prospective solvents for the extraction systems for separation An(III) and Ln(III). 19 Metanitrobenzotrifluoride (F-3) is one of the most prominent representatives of this class of solvents. It has high solubilizing ability of polar compounds, chemical, radiation, fire, and explosion resistance.…”

“…19−21 Extraction systems based on the F-3 solvent with the N,O-donor ligand are currently under active investigation. 3,9,12,19,22 Hydrophobic ionic liquids are another type of diluents that can be used in extraction systems for the separation of felements. 23−27 These compounds exhibit exceptional physicochemical properties, being nonvolatile, nonflammable, and possessing high ionic conductivity as well as the thermal and electrochemical stability.…”

In this work, we studied the extraction systems for the separation f-elements based on the tetradentate N,O-donor ligand di(N-ethyl-4-ethylanilide) 2,2′-dipyridyl-6,6′-dicarboxylic acid (L). The organic phase of these systems was perspective fluorine-containing organic solvents−metanitrobenzotrifluoride (F-3), ionic liquid C 4 mimNTf 2 (IL), and their mixture. The increase of Am(III) selectivity in the presence of Ln(III) in cases of the diluent mixture was shown. The mechanism of the f-element complexation leading to the improved properties of the extraction systems was studied by UV−visible, Raman-spectroscopy, XRDstudy, and density functional theory calculations.

“…For this reason, we used solvent F-3 ( meta -nitrobenzotrifluoride) to compare the ligands under the same conditions. The advantages of F-3 over classical nonpolar solvents are that it has a high explosion and fire safety in contact with nitric acid solutions and prevents forming a third phase. , …”

The search for new effective extractants is an important task for the management of high-level liquid waste (HLW) generated during the reprocessing of spent nuclear fuel. Here, we synthesized a series of diglycolamides with cyclic substituents for the first time. We disclosed their coordination with f-element nitrates [La(NO 3 ) 3 and UO 2 (NO 3 ) 2 ] by SC-XRD study and complexation properties toward Am(III), Ln(III), and U(VI) during solvent extraction from nitric acid solutions. Using dynamic nuclear magnetic resonance (NMR) and density functional theory (DFT) calculations, the importance of tautomerism in the extraction properties of diglycolamides was shown.
