“…The reference data by Leachman et al [35] showed liquid density and gas and liquid molar enthalpy values at temperatures between 14 and 21 K that yield the expression shown in Table 3 and H ( b ) = 5.08 MPa 1/2 . Sistla et al [36] quote Hansen [2] and report d = 5.1 MPa 1/2 at 298 K and 1 atm for the dispersion partial solubility parameter. The well agreeing value from three authors, H ( b ) = 5.08 MPa 1/2 , is the selected value.…”

“…The experimental latent heat of vaporization (at an unspecified temperature, presumably b ) of 201.2 J g −1 yields with = 0.8801 g cm −3 the value H ( b ) = 12.02. Sistla et al [36] quote Hansen [2] and report d = 11.9 MPa 1/2 at 298 K and 1 atm for the dispersion partial solubility parameter. The mean value from the five mutually agreeing reports, H ( b ) = 11.95, is selected here.…”

“…These yield with the density data the following solubility parameter values: H ( ) MPa 1/2 = 15.11, 13.56, and 11.13 at these three temperatures, interpolating to H ( b ) MPa 1/2 = 14.55 and yielding the data shown in Table 3. Sistla et al [36] quote Hansen [2] and report d = 11.9 MPa 1/2 at 298 K and 1 atm for the dispersion partial solubility parameter. From the four agreeing values at the boiling point, the average H ( ) MPa 1/2 = 14.64 ± 0.07 is taken as selected.…”

“…Atake and Chihara [55] reported Δ V /J mol −1 = 16544 and with the density data of Leadbetter et al [56] yielding ( b ) = 35.64 cm 3 mol −1 this produced H ( b )/MPa 1/2 = 20.52. Sistla et al [36] quote Hansen [2] and report d = 11.5 MPa 1/2 at 298 K and 1 atm for the dispersion partial solubility parameter, but the total, Hildebrand solubility parameter included a contribution from the polar interactions of these gas molecules, adding up to H (298 K) MPa 1/2 = 20.81. The average of these agreeing values, 20.58 ± 0.20, is selected here.…”

“…These values yield H ( b )/MPa 1/2 = 21.69. Sistla et al [36] quote Hansen [2] and report d = 17.0 MPa 1/2 at 298 K and 1 atm for the dispersion partial solubility parameter, but the total, Hildebrand solubility parameter included a contribution from the polar interactions of these gas molecules, adding up to H (298 K)/MPa 1/2 = 20.71. The average of the values resulting from [86,89], H ( b )/MPa 1/2 = 20.72, nearly coincides with the latter value (for 298 K).…”

The solubility parameters,δH(Tb), of nonreactive permanent gases at their boiling pointsTb(<290 K) are calculated from individually discussed values of their molar enthalpies of vaporization and densities obtained from the literature. These values are tabulated and where available the coefficients of the temperature dependence expressionδH(T)are also tabulated. The trends noted in theδH(Tb)values are dealt with and the values are compared with those reported in the literature and derived from the solubilities of the gases in various solvents. TheδH(Tb)values are shown to correlate linearly with the depths of the potential wells (attractive interaction energies,ε/kB) for binary collisions of the gaseous molecules and with the surface tensions,σ(Tb), of the liquefied gases.

Determination of Solubility Parameters of Ionic Liquids and Ionic Liquid/Solvent Mixtures from Intrinsic Viscosity

et al. 2014

The total and partial solubility parameters (dispersion, polar and hydrogen-bonding solubility parameters) of ten ionic liquids were determined. Intrinsic viscosity approaches were used that encompassed a one-dimensional method (1D-Method), and two different three-dimensional methods (3D-Method1 and 3D-Method2). The effect of solvent type, the dimethylacetamide (DMA) fraction in the ionic liquid, and dissolution temperature on solubility parameters were also investigated. For all types of effect, both the 1D-Method and 3D-Method2 present the same trend in the total solubility parameter. The partial solubility parameters are influenced by the cation and anion of the ionic liquid. Considering the effect on partial solubility parameters of the solvent type in the ionic liquid, it was observed that in both 3D methods, the dispersion and polar parameters of a 1-ethyl-3-methylimidazolium acetate/solvent (60:40 vol %) mixture tend to increase as the total solubility parameter of the solvent increases.
