ABSTRACT

Conductivities for ionic liquids (ILs) 1-alkyl-3-methylimidazolium chloride ([Cnmim]Cl, n = 4, 6, 8, 10) + sucrose + water solutions and [C4mim]Cl + maltose + water solutions were measured at 298.15 K. Meanwhile, densities, viscosities, and relative permittivities for water + disaccharide mixtures were also measured. The Lee Wheaton conductivity equation was used to acquire the limiting molar conductivities (0). The Walden products (00) were also calculated. The interaction of ILs with disaccharide was discussed in terms of the structure of disaccharides and ILs. Furthermore, values of 0 for inorganic salts (ordinary electrolyte, such as NaCl/KCl) and ILs (special electrolyte) were compared, indicating that they have approximate limiting molar conductivities, namely, they have not too much difference in electrical conductivity.
