Surface tension of binary mixtures of imidazolium and ammonium based ionic liquids with alcohols, or water: Cation, anion effect

Micellization and interfacial behavior of imidazolium-based ionic liquids in organic solvent–water mixtures

“…The effect of several organic solvents on traditional surfactant systems has been exhaustively studied [31][32][33][34]. A limited amount of literature has examined the correlation of solvent properties and ILs [20][21][22], but there is a lack of information about these effects on IL-aggregates.…”

“…In addition, IL and organic solvent mixtures are becoming more widely studied in various extraction, synthetic, and separation methodologies. The values of the critical micelle concentration (cmc), the maximum surface excess concentration (Γ max ), the minimum surface area per surfactant molecule ( A min ), the surface tension at the cmc (γ cmc ), the adsorption efficiency (pC 20 ), and the effectiveness of surface tension reduction (Π cmc ), are reported in this work for both ILs and the studied organic solvents. The utility of the HDBIm-Br IL in MLC is also evaluated.…”

“…In spite of these studies of IL-aggregation in water (binary systems), a limited amount of literature has examined the effect of organic solvents in aqueous solutions of ILs [20][21][22]. However, up to this date, there are no exhaustive studies that examine the influence of organic solvents on the interfacial behavior of IL-aggregates.…”

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.…”

Effect of Water Content on Properties of Homogeneous [bmim]Fe(III)Cl4–H2O Mixtures and Their Application in Oxidative Absorption of H2S

“…Additional studies indicated that the presence of water in ionic liquids that have no metal affected their physical and chemical properties. The surface tension of ammonium ionic liquids in aqueous solutions increased non-linearly with water content [13]. The viscosity of hydrophilic 1-butyl-3-methylimidazolium-based ionic liquids also strongly depends on water content [14].…”
