“…Recently, ionic liquid-based solvents have been found to feature phase behavior characteristics. Kassim et al (Kassim et al 2016) found that the mixture of MEA and 1-butyl-3methylimidazolium bis (trifluoromethylsulfonyl) imide ([BMIM][NTf 2 ]) in sulfolane formed a novel phase change solvent; however, its regeneration efficiency was less than 50%. Due to outstanding properties, including negligible vapor pressures, high thermal stability, and structure tunability, amino-functionalized ionic liquid (AFIL) biphasic solvents are regarded as an efficient absorbent that has outstanding CO 2 capture performance and the proper phase separation behavior.…”

Amino-functionalized ionic liquid biphasic solvents present excellent absorption capacity, regeneration ability, and energy consumption savings, which make them a possible candidate for CO 2 capture. The kinetics and regeneration heat duty of the [TETAH][Lys]-ethanol-water system capturing CO 2 were investigated in this work. The mass transfer and kinetic parameters, including the overall reaction rate constant (k ov), the reaction rate constant (k 2), and the enhancement factor (E), were assessed at diverse concentrations and temperatures. At 303.15 K, the k 2 of CO 2 capture into the [TETAH][Lys]-ethanol-water solution was 58,907.30 m 3 kmol −1 s −1. The Arrhenius equation was introduced to evaluate the relations between k 2 and the reaction temperature, which can be presented as k 2; TETAH ½ Lys ½-ethanol-water ¼ 1:9941 Â 10 15 exp − 7388:1 T À Á The regeneration heat duty of the novel biphasic solvent was 35.5 and 62.39% lower than those of [TETAH][Lys]-water and the benchmark monoethanolamine solution, respectively. An efficient absorption performance and lower energy requirement indicate the great potential for this application.

Density, speed of sound, and viscosity values were measured for different binary mixture concentrations of 1-butyl-3methylimidazolium bis(trifluoromethylsulfonyl)imide ([Bmim][NTf 2 ]) + N-methylaniline (NMA) and 1-butyl-3-methylimidazolium hexafluorophosphate ([Bmim][Pf 6 ]) + NMA systems at temperatures from T = 298.15 to 323.15 K under atmospheric pressure. The excess values of molar volume, molar isentropic compressibility, intermolecular free length, and viscosity were calculated. The partial molar volumes and partial molar isentropic compressibilities at infinite dilutions were also estimated. The Redlich−Kister equation was utilized to evaluate coefficients and standard deviations. The mechanism of effective packing between [Bmim][NTf 2 ]/ [Bmim][Pf 6 ] and NMA was represented by the negative excess molar volumes. In both the studied systems, the occurrence of strong chemical interactions was represented by the negative excess intermolecular free length values. The present work clearly showed that the simultaneous analysis of excess properties could provide a comprehensive description of molecular interactions occurring in the binary mixtures, specifically if the component molecules have different sizes. Further, the high viscosities of the ionic liquids were decreased by mixing with low viscous NMA. Hence, the investigated systems could be more suitable for their possible applications in the transport mechanism and absorption of gasses.

The density and speed of sound data were determined for various binary compositions of 1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([Bmim][NTf2]) (1) and 2-methoxyethanol (2) at different temperatures. These data were utilized to calculate different acoustic and thermodynamic parameters. The variations in these parameters were analyzed to know the behavior of molecular interactions present between the chemical species. The Redlich–Kister equation was used to estimate the deviation between the calculated and experimental excess values. Furthermore, experimental FT-IR analysis was also used to study the interactions between the chemical species.
