“…The NIST Standard Reference Database #103b [58] and some newly published papers [59][60][61][62][63] were used to extract experimental data for surface tension of ionic liquids. In the next step, the data gathered were analyzed and screened to remove duplicates and outliers.…”

In this study, the Guggenheim equation was used to estimate the critical temperature (T c) of 106 ionic liquids using experimental surface tension data as inputs. A group contribution (GC) and a Quantitative Structure−Property Relationship (QSPR) model were also developed to correlate/predict the T c of ionic liquids. It was shown that a lack of sufficiently large database for T c lead to the development of models with low prediction capability. The model's output as well as the T c values estimated from the surface tension data were compared with the critical temperatures calculated by the Valderrama et al. method. The results showed that the Valderrama et al. method produces different data values compared with the values calculated by the Guggenheim equation. Neither the GC, QSPR, nor Valderrama's method is capable of reliable prediction of the T c of ionic liquids. Consequently, the calculated T c values are not reliable enough to be used in the development of corresponding state models for prediction of other thermophysical properties of ionic liquids. Any usage of critical properties of ionic liquids should be done with a serious caution.

“…The imidazolium-based RTILs are excellently soluble in most polar solvents 1,2,11,13,15,17,[20][21][22][23][24][25][26][27][28][29][30][31][32][38][39][40][41][42][43][44] and are relatively cheap to synthesize. Polar molecular co-solvents, such as water, methanol, acetonitrile, acetone, n-butanol, alter physical and chemical properties of the imidazolium-based RTILs drastically.…”

a b s t r a c tImidazolium-based ionic liquids are widely used in conjunction with molecular liquids for various applications. Solvation, miscibility and similar properties are of fundamental importance for successful implementation of theoretical schemes. This work reports competitive solvation of the 1,3-dimethylimidazolium cation by water and methanol. Employing molecular dynamics simulations powered by semiempirical Hamiltonian (electronic structure level of description), the local structure nearby imidazolium cation is described in terms of radial distribution functions. Although water and methanol are chemically similar, water appears systematically more successful in solvating the 1,3-dimethylimidazolium cation. This result fosters construction of future applications of the ternary ion-molecular systems.

“…The viscometer (Zhejiang Jiaojiang Glass Instrument Factory, Taizhou, China) was calibrated in a super constant temperature bath (Shanghai Pingxuan Scientific Instrument Co. LTD, Shanghai, China, ±10 −2 K) with glycerol, glycol, and water. The viscosity was detected by the Pinkevitch method (according to GB/T 10247-2008), and the viscosity meter was calibrated by glycerol [39,40]. H-NMR spectra were collected on a Bruker AVANCE II 400 M spectrometer using d6-DMSO as the solvent and TMS as the internal standard.…”

The viscosity (9.34–405.92 mPa·s) and absorption capacity (0.4394–1.0562 g·g−1) of (1-ethyl-3-methylidazolium trifluoroacetate + triethanolamine) binary blends atmospheric pressure in the temperature range of 303.15–343.15 K and at different mole fractions of [EMIM] [TFA] have been carried out. The molar fraction of [EMIM] [TFA] dependence of the viscosity and absorption capacity was demonstrated. The addition of a small amount of [EMIM] [TFA] into TEA led to rapidly decreased rates of binary blends’ viscosity and absorption capacity. However, the viscosity and absorption of binary blends did not decrease significantly when [EMIM] [TFA] was increased to a specific value. Compared with the molar fraction of the solution, the temperature had no obvious effect on viscosity and absorption capacity. By modeling and optimizing the ratio of viscosity and absorption capacity of ([EMIM] [TFA] + TEA), it is proven that when the mole fraction of [EMIM] [TFA] is 0.58, ([EMIM] [TFA] + TEA) has the best viscosity and absorption capacity at the same time. In addition, at 303.15 K, ([EMIM] [TFA] + TEA) was absorbed and desorbed six times, the absorption slightly decreased, and the desorption increased.
