Phase equilibria and energetics of binary mixtures of water with highly hydrophilic [EMIM]-based ionic liquids: Methanesulfonate, methylsulfate, and dimethylphosphate

Physicochemical and Thermodynamic Investigation of Ethanolic Solution of Phosphonium-Based Ionic Liquids─Measurements, Correlations, and Application to Absorption Cycles

“…To the best of our knowledge, no data about the [C 1 Py]­[DMP] density is presented. In the open literature, there are a few density data for pure [C 1 C 1 IM]­[DMP], ,− or [C 1 C 2 IM]­[DMP] − and their ethanolic solution. ,,, Figure S7 in the SI shows the relative deviations between the data measured in this work and the literature results at a temperature of 298.15 K for pure imidazolium-based ILs.…”

“…In the open literature, there are a few viscosity data for pure [C 1 C 1 IM]­[DMP], ,,,, [C 1 C 2 IM]­[DMP], − , and their binary ethanolic solution. ,,, To the best of our knowledge, there is no data literature data on the viscosity of the [C 1 Py]­[DMP] for comparison. Literature data varies widely, and the declared viscosity value for pure [C 1 C 1 IM]­[DMP] at 298.15 K ranges from (223 to 337) mPa·s.…”

“…Thermodynamic data are required to assess the suitability of using IL’s ethanolic solution as an alternative working pair in absorption refrigeration. Numerous articles in the literature show the thermodynamic and physicochemical characteristics of pure ILs based on dimethyl phosphate, including liquid density, − viscosity, ,,,,, or heat capacity. ,, Systems of this type of ionic liquid with ethanol have less information accessible. The information that is currently accessible relates to the densities, viscosities, or heat capacities of binary IL systems with the following cations: 1,3-dimethylimidazolium, ,, 1-ethyl-3-methylimidazolium, , 1-butyl-3-methylimidazolium, 1-ethyl-1-methylpyrrolidinium, 1-hydroxyethyl-1-methyl-pyrrolidinium, 1-ethyl-1-methylmorpholinium, 1-ethyl-1-methyl-piperidinium, and N,N,N -triethyl- N -methylammonium …”

Phase Equilibria, Thermodynamic Behavior, and Transport Properties of Aqueous Solutions of [BMPYR] Trifluoromethanesulfonate and [BMPYR] Tricyanomethanide

“…NRTL model has been widely proved to perform adequately for the purpose in our previous studies. [1][2][3][4][5][6]8 Bearing in mind that the selection of accurate data and rational fitting strategy are also important prerequisites for establishing a globally performing model, the procedure we adopted for the evaluation of adjustable parameters was as follows. For the (water + [BMPYR][OTF]) system, the VLE and H E data measured in this work were simultaneously correlated using the weighted least-squares method, the objective function minimalized being…”
