“…It was noted that the densities of all the studied system decreases with increasing temperatures. This similar trends has been observed for; [EMIM][SCN] + Water, 1 [BMIM][NtF 2 ] + Sulfolane, Glycerol + Sulfolane , 32 [BMIM][NtF 2 ] + [BMIM][SCN], [BMIM][NtF 2 ] + [BMIM] [N (CN) 2 ], [BMIM][NtF 2 ] + [BMIM] [C (CN) 3 ], [BMIM][NtF 2 ] + [BMIM][BF 4 ], [BMIM][NtF 2 ] + [BMIM][PF 6 ], [BMIM][NtF 2 ] + [BMIM][OAc], [BMIM][NtF 2 ] + [BMIM][TFO], [BMIM][NtF 2 ] + [BMIM][DMP] 33 . Further, the variation of the measured density with temperature for all the studied system were correlated by polynomial equation and it's illustrated in Figure – S13 .…”

Densities of the binary mixtures of organic solvents (acetic acid (HAc), n‐butanol (n‐BuOH) and n‐ butyl acetate (n‐BuAc)) with 1‐ethyl‐3‐methylimidazolium hydrogen sulphate {[EMIM][HSO4]: IL1}, 1‐ethyl‐3‐methyimidazolium ethyl sulphate {[EMIM][EtSO4]: IL2}, 1‐butyl‐3‐methylimidazolium acetate {[BMIM][OAc]: IL3}, 1‐butyl‐3‐methylimidazolium bis (trifluoromethylsulfonyl)imide, {[BMIM][NtF2]: IL4}} and/or Deep Eutectic Solvents (DESs) {choline chloride‐acetic acid [ChCl][AA]: DES1}, choline chloride‐glycerol [ChCl][Gly]: DES2), were measured over the entire composition range at T (293.15–343.15) K and 1 atm. The volumteric properties and derived thermodynamic properties of mixed solvents were calculated from the experimental data in order to understand the specific interactions and/or non‐specific interactions between mixed solvents during mixing at 298.15 K and 1 atm. Further, the molecular polarity of all the studied components were analyzed using COSMO‐RS model.

“…145 The σ-profile histograms can be split into three regions: HBD (σ < −0.0082 e Å −2 ), non-polar region (−0.0082 e Å −2 ≤ σ ≤ 0.0082 e Å −2 ) and HBA region (σ > 0.0082 e View Article Online Å −2 ). 147,[173][174][175] The nature of the interaction among the components can be described qualitatively according to these plots. First, it can be seen that the σ-profile of H 2 O is approximately bimodal, showing maxima in the regions close to σ ∼ −0.015 e Å −2 and σ ∼ +0.015 e Å −2 , which relate strongly to its HBD and HBA capacities, respectively.…”

“…The behavior of density, speed of sound, and viscosity with x 1 and temperature, in systems 1 and 2, demonstrates that the physicochemical properties of pure ILs ([Bmim][NTf 2 ]/[Bmim][Pf 6 ]) could be modified in a selective manner by adding NMA or by varying temperature. The viscosity values of these ILs with different organic solvents were determined by various researchers. ,,− Compared to the literature, the present investigated systems showed lower viscosity values because of the usage of NMA. Hence, the present systems could be more suitable for their possible applications in transport mechanism and absorption of gasses.…”

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.
