“…Although in previous research for the influence of anions in ILs on the formation of IL-ABS developed a little slower than the cations, , this topic has aroused people’s interest owing to anion’s higher aptitude for hydration . In the past, our group systematically investigated ILs + inorganic salts + water, ILs + organic salts + water, and ILs + organic solvents to obtain the extractive properties. ,− Nonetheless, most of the works have mainly focused on the influence of the organic solvents or salts, and there is a great lack of comprehensive analysis of the anion effect.…”

Recently, ionic liquids (ILs) were widely used to form aqueous biphasic systems (ABSs). In this study, a systematic investigation involving various ILs was studied to provide more information on forming IL-ABSs. For this purpose, based on the IL cations, n-butylpyridinium trifluoromethanesulfonate, n-butylpyridinium tetrafluoroborate, and nbutylpyridinium nitrate, the influence of anions of the IL on forming ABSs was evaluated. The cation effect between 1-nbutyl-4-methylpyridinium tetrafluoroborate and n-butylpyridinium tetrafluoroborate was discussed. Besides, bimodal curves data of all the studied ABSs were measured and presented. The binodal curves were then correlated by the Merchuk equation with values of R 2 > 0.9966, which is widely used to fit the binodal curves. Moreover, the influence of temperature on ABSs was studied for [4-MBP]BF 4 + (NH 4 ) 2 SO 4 + water. The two-phase region in the diagram is found to increase as the temperature decreases.

“…That is, a decrease in temperature leads to an increase in phase-forming ability. Novel ATPS composed of N -butylpyridinium tetrafluoroborate ([C 4 py][BF 4 ]) and inorganic salts (Na 2 SO 4 and (NH 4 ) 2 SO 4 ) were studied [ 68 ]. The two-phase region expanded with the decrease in temperature, which indicated that the low temperature was favorable for the phase separation.…”

As an environmentally friendly separation medium, the ionic liquid (IL)-based aqueous two-phase system (ATPS) is attracting long-term attention from a growing number of scientists and engineers. Phase equilibrium data of IL-based ATPSs are an important basis for the design and optimization of chemical reactions and separation processes involving ILs. This article provides the recent significant progress that has been made in the field and highlights the possible directions of future developments. The effects of each component (such as salting-out agents and ILs) on the phase behavior of IL-based ATPSs are summarized and discussed in detail. We mainly focus on the phase behavior of ATPSs by using ILs, expecting to provide meaningful and valuable information that may promote further research and application.
