Volumetric Study of Binary Solvent Mixtures Constituted by Amphiphilic Ionic Liquids at Room Temperature (1-Alkyl-3-Methylimidazolium Bromide) and Water

Physical Properties of Binary Mixtures of ILs with Water and Ethanol. A Review.

“…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.…”

Synthesis and micellar properties of surface-active ionic liquids: 1-Alkyl-3-methylimidazolium chlorides

“…Indeed, conductimetric, potentiometric, surface tension and volumetric (from solution density) studies have indicated that C 10 MeImBr aggregates in water and, at low concentrations, behaves as a classic cationic surfactant [20,21]; surface tension measurements have indicated a similar behavior of C 16 MeImCl and C 16 MeImBF 4 both in aqueous solution, and in the IL ethylammonium nitrate [22]. A few articles dealt with other physico-chemical properties of longchain RMeImX, including their partition coefficients between n-octanol and water (RMeImCl, R = C 8 , C 10 , and C 12 , respectively) [23]; solubility of C 12 MeImCl in several alcohols [24] and dipolar aprotic solvents [25].…”

Volumetric and Isentropic Compressibility Behavior of Ionic Liquid, 1-Propyl-3-Methylimidazolium Bromide in Acetonitrile, Dimethylformamide, and Dimethylsulfoxide at T = (288.15 to 308.15) K

“…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.…”
