“…To recover IPA by liquid–liquid extraction, the extractant selection has been reported in some literatures, for instance, organic solvents, − deep eutectic solvents, , and ionic liquids (ILs). − ILs have been applied in the separation field due to their superiority in designability, thermal stability, and negligible vapor pressure. − Cumplido et al − performed the liquid–liquid equilibrium (LLE) exploration for the mixture water + IPA with different imidazolium-based ILs at temperatures of 283.2–323.2 K. All the used ILs played a positive role in recovering IPA from the azeotropic mixture. Liu et al determined the LLE behavior for water + IPA with the ILs 1-hexyl-3-methyl imidazolium bis(trifluoromethylsulfonyl)imide ([Hmim][NTf 2 ]), 1-octyl-3-methyl imidazolium bis(trifluoromethylsulfonyl)imide ([Omim][NTf 2 ]), and 1-decyl-3-methyl imidazolium bis(trifluoromethylsulfonyl)imide ([Dmim][NTf 2 ]) at 298.15 K. The results demonstrated that the ionic liquid with the longer alkyl chain length exhibited a strong ability to recover IPA.…”

Three pyridinium-based ionic liquids (ILs) were adopted to extract isopropanol (IPA) from its aqueous mixture for investigating the potential of these ILs in the separation of a (water + IPA) azeotropic mixture. The liquid–liquid equilibrium values for the mixtures (water + IPA + ILs) was determined at 298.15 K. The selectivity and distribution coefficient were computed, which indicates that the IL n-hexylpyridinium bis(trifluoromethyl sulfonyl)imide displays a better extraction effect to separate the mixture of IPA and water. Besides, the NRTL model was applied to regress the determined tie-line values, and the coherence of the optimized binary parameters was examined using the Gibbs energy surfaces analysis.

“…Moreover, to show the temperature effect on the tie-line compositions, the tie-line lengths (TLL) and slopes (TLS) are calculated using the following equations: Calculated TLL and TLS values are reported in Table and shown in Figures and as a function of salt concentration in stock solution. These results show that TLLs and TLSs were increased with increasing the temperature, which also reveals that the extent of the two-phase region increased with increasing the temperature.…”

“…1 These methods are affordable, easy to scale up, fast, and environmental friendly because water is the main component of these systems. 2 Different types of ATPSs such as polymer + polymer + water, 3 polymer + salt + water, 4 ionic liquid + mineral salt + water, 5 deep eutectic solvent + salt + water, 6 and alcohol + salt + water 7 have been reported in the literature. However, ATPSs composed of chemicals such as chitosan polymer, deep eutectic solvents, and ionic liquids are not appropriate in the industrial scale due to their high cost.…”

Temperature Effect on the Liquid–Liquid Equilibrium of Isopropanol + Trisodium Citrate + Water Aqueous Two-Phase Systems at T = 288.15, 298.15, 308.15, and 318.15 K

In this study, the temperature effect on the aqueous two-phase systems composed of isopropanol + trisodium citrate + water was studied by experimental measurement of the binodal curves and tie-line compositions at T = 288.15, 298.15, 308.15, and 318.15 K temperatures. It was found that the salting-out ability of the system was increased with increasing the temperature so that the extension of the two-phase area, especially in the salt-rich region, was increased by raising the temperature. Correlation of the tie-line compositions to a Seteschenow-type equation also showed that the two-phase formation tendency of the studied systems has a positive correlation with the salting-out parameters, K ca , of this equation so that K ca values were increased with increasing the temperature. Binodal curves at all studied temperatures were successfully fitted to two temperature-dependent equations with only three fitting parameters, simultaneously. Also, the electrolyte-Wilson model was modified as a function of temperature and used for simultaneous correlation of the tie-line data at all studied temperatures. An excellent agreement between the calculated values of the modified electrolyte-Wilson model and the experimental results was obtained.

“…The NRTL model is known to be robust and flexible enough for modeling both ternary LLE data and binary subsystems using a common parameter setthe binary interaction parameters τ ij . Several works have shown the adequacy of using the NRTL model to describe organic–IL binary mixtures, as well as salt–IL or polymer–salt ABS. − However, determining these parameters set by fitting the model to ternary experimental TLs may lead to poor descriptions of the binary subsystems. To the best of our knowledge no binary interaction parameters exist for the studied binary subsystems.…”

Liquid–Liquid Equilibrium and Extraction Performance of Aqueous Biphasic Systems Composed of Water, Cholinium Carboxylate Ionic Liquids and K₂CO₃

et al. 2019

Ionic-liquid-based aqueous biphasic systems (ILbased ABS) have been broadly investigated for the separation of high-value compounds. Nevertheless, the large-scale application of IL-based ABS is still hampered by the high cost and hazardous features of most ILs used. Aiming at characterizing novel ABS composed of ILs with a more acceptable environmental footprint and enhanced biocompatibility, in this work, ABS formed by water, cholinium carboxylate ILs ([Ch][C n CO 2 ], with n = 2 to 6), and K 2 CO 3 were investigated. The respective ternary phase diagrams, including binodal curves, tie-lines, and critical points, were determined at (298 ± 1) K and atmospheric pressure. The capability to form ABS (or of the IL to be salted-out) increased with the increase of the alkyl chain length of the IL anion up to cholinium pentanoate; however, for longer anion alkyl chain lengths the ILs self-aggregation led to a decrease of the ILs ability to form ABS. Furthermore, the liquid−liquid equilibrium data experimentally determined were modeled using the local composition activity model NRTL (nonrandom two liquid). The extraction performance of these systems was finally evaluated with four nitrogenous bases (thymine, adenine, guanine, cytosine). In all studied systems nitrogenous bases preferentially migrated to the IL-rich phase, with extraction efficiencies ranging between 81% and 97% in a single-step. The determined novel phase diagrams indicate the composition of the mixtures required to use IL-based ABS as separation routes. The extraction performance evaluation of these systems with nitrogenous bases provides an indication of their possible application to isolate high-value compounds with biotechnological interest.
