Conductivities for
ionic liquids (ILs) 1-alkyl-3-methylimidazolium
chloride ([C
n
mim]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 (Λ0). The Walden products (Λ0η0) were also calculated. The interaction of ILs with disaccharide
was discussed in terms of the structure of disaccharides and ILs.
Furthermore, values of Λ0 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.
