“…[33, 34] The values observed in water are comparatively larger than the ones found in DMF; probably on account of special pathway of diffusion offered by structured solvents like water for the field induced diffusion of charged species. The limiting diffusion coefficients and limiting molar conductivities of the two electrolytes seem to be predominately determined by the nature of anions, in agreement with previous reports related to transport parameters of salts with bulky cations . The observed order of limiting diffusion coefficient of anions is: D(Br − /WATER)> D(MeS0 4 − /WATER)> D(Br − /DMF)> D(MeS0 4 − /DMF).…”

A systematic study of electrical conductivity, density and viscosity over solutions of tetraethylammonium bromide(TEAB) and 1-butyl-3-methylimidazolium methylsulfate ([BMIM] [MeSO 4 ]) in variedly composed dimethyl formamide (DMF) plus water mixtures was carried to explore the potential advantages of such mixed solvent systems for electrochemical investigations. The estimated transport and bulk characteristics of TEAB and [BMIM][MeSO 4 ] in the mixed solvent revealed strong composition dependent interactions are present in the DMF-Water mixed solvent systems. Such results intrigued us to study the impact of solution properties of DMF-water systems on electrochemical behavior of redox probe para-nitrotoluene (PNT).The estimated transport, kinetic and thermodynamic parameters were correlated with the estimated values for viscosity, density and calculated values of dielectric constant for the mixed solvent. The kinetics of PNT was found to be controlled by outer sphere solvent reorganization in DMF-water solvent system for both the supporting electrolytes viz. TEAB and [BMIM][MeSO 4 ], upto composition range of 0.35 mole fraction of DMF in water.

“…In this paper we present the synthesis and structure of a new family of ILs, majority of them never described before. This family is based in the already known IL 1-butyl-3-methyl imidazolium thiocyanate, BMIM(SCN), a commercial IL which has been studied in many papers, both pure [9][10][11][12][13] and forming part of different mixtures with water [14][15][16], alcohols [17][18][19][20][21] or other solvents [14,15], and even with other ILs with the same cation [22]. In addition, it has been also studied the parent compounds with 1-ethyl-3-methyl imidazolium, EMIM(SCN) [13,23,24] and 1-hexyl-3-methyl imidazolium HMIM(SCN) [25][26][27].…”

“…One reason for this observed inversion of the expected order could be the lack of enough experimental data in the diluted region (0<XIL<0.15). According to Canongia Lopes et al [34], most small dipolar solvents dissolve the polar network of ILs' and will be able to interact directly with the ions that compose it. The difference between the systems with DMSO and ACN, both solvents having high dipole moments, can be explained by their specific structural features.…”

“…In literature the reciprocal poise (P -1 ) is used as a unit for fluidity, while S•cm 2 •mol -1 is used for molar conductivity. This Walden plot serves as a reliable means for quantification of ion association in neat ILs and includes the "ideal" Walden line, which represents the Walden plot for 0.01 mol•dm -3 KCl aqueous solution, known to be fully dissociated and having ions of equal mobility [34,43]. For such ideal dilute aqueous KCl solution no interaction occurs among the constituent ions.…”

This paper reports experimental electrical conductivities data of eight binary systems of four ionic liquids: 1-butyl-3-methylimidazolium tetrafluoroborate, [Bmim][BF4], 1-hexyl-3-methylimidazolium tetrafluoroborate, [Hmim][BF4], 1-butyl-3-methylimidazolium hexafluorophosphate, [Bmim][PF6] and 1-butyl-2,3-dimethyl-imidazolium tetrafluoroborate, [Bmmim][BF4] with the organic solvents dimethyl sulfoxide (DMSO) and acetonitrile (ACN) at atmospheric pressure and temperatures from 298.15 to 328.15 K. It was found that conductivities in the investigated ionic liquids follow the order: [Bmim][BF4] ] [Bmim][PF6] ][Bmmim][BF4] ] [Hmim][BF4]. Experimental results demonstrate that the binary mixtures possess higher electrical conductivity compared with pure components. Electrical conductivity data were correlated using Casteel�Amis and Arrhenius equations. The molar conductivity was derived from experimental data and fitted to Walden rule. The influence of the cation structure and anion type on the conductivity was discussed, which help understanding the intermolecular interactions in the binary systems. A deeper understanding of the transport behavior of ILs is given by means of density functional theory calculations (DFT)
