“…In Figure 2 we plot BMIM, HMIM and OMIM-Cl aqueous systems (Gomez et al, 2006a;Yang et al, 2010), being the BMIM-Cl only partially miscible (for x IL < 0.5). These systmes have been also measured by other authors with very similar results (Gaillon et al, 2004;Zafarani et al, 2005;Gardas et al, 2008;Dong et al, 2009;Calvar et al, 2007). As observed density increases from the pure IL value when water is added for HMIM-Cl and OMIM-Cl, and them it decreases for more water content.…”

“…The viscosity variations of PYR 14 -MeOH exhibit unusual behavior similar only to a few cases reported in the literature [30,31]. Effectively, at 293.15 K, the viscosity of the pure IL falls by 56% when 21 mol % of methanol is added and for the mixture it increases with x 1 .…”

Densities, viscosities, and ionic conductivities were measured for the binary mixtures containing the ionic liquid Nbutyl-N-methylpyrrolidinium bis(trifluoromethanesulfonyl) imide and methanol over the entire range of compositions at the temperature varying from 253.15 to 318.15 K. The densities and viscosities decrease monotonously with temperature and the content of ionic liquids (ILs). Furthermore, excess isobaric expansion coefficient has been calculated from the experimental densities. The dependence of temperature on the viscosity has been fitted to the Arrhenius law with high precision. The dependence of temperature on the ionic conductivity has also been gauged by both of the Arrhenius and Vogel-Tamman-Fulcher (VTF) equations. In fact, the shape of the curves shows that the temperature dependence of the conductivity does not follow a simple Arrhenius law, but a better fitting of experimental results is achieved using the VTF model. Additionally, the effects of ILs concentration on the viscosity and the conductivity have been examined using the Walden rule, which shows that the variation of conductivity is inversely proportional to viscosity. Excess molar volumes and viscosity deviations for all mixtures are evaluated and well fitted to the Redlich-Kister polynomial expansions. Physicochemical properties show two clearly distinguished behaviors corresponding to ILsrich and methanol-rich regions, with distinct transport and volumetric properties. The obtained results are discussed in terms of dipolar interactions and hydrogen bonding establishment between ions of ILs and the methanol molecules.

“…The volumetric and acoustic properties of electrolytic and nonelectrolytic solutions have proved particularly informative in elucidating the solute-solute and solute-solvent interactions. In spite of their importance, there is limited information on the thermodynamic properties of 1-alkyl-3-methylimidazolium bromide in aqueous or nonaqueous solutions [16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31]. As a continuation of our previous study [31] on the thermodynamic properties of the 1-alkyl-3-methylimidazolium bromide solutions, we report here new density and speed-of-sound measurements on mixtures of 1-propyl-3-methylimidazolium bromide ([C 3 mim][Br]) with acetonitrile (MeCN), dimethylformamide (DMF), and dimethylsulfoxide (DMSO) over the range of temperature from 288.15 K to 308.15 K at 5 K intervals in the dilute concentration region.…”

Density and speed-of-sound data for 1-propyl-3-methylimidazolium bromide ([C 3 mim][Br]) + acetonitrile (MeCN), [C 3 mim][Br] + dimethylformamide (DMF), and [C 3 mim][Br] + dimethylsulfoxide (DMSO) binary mixtures in the dilute concentration region are reported at T = (288.15 to 308.15) K. From these data, apparent molar volume, isentropic compressibility, excess molar volume, and isentropic compressibility deviation values have been calculated. Negative deviations from the ideal behavior of both molar volume and isentropic compressibility have been observed for all systems investigated in this study. It has been found that deviations from ideal behavior for the [C 3 mim][Br] + MeCN system are larger than those for the [C 3 mim][Br] + DMF system which, in turn, are larger than those for the [C 3 mim][Br] + DMSO system. The results have been interpreted in terms of ion-dipole interactions and structural factors of the ionic liquid and investigated organic solvents.
