Using these properties, the apparent molar volumes, V φ , the viscosity B-coefficients and the molar conductivities, Λ m, have been computed for the ternary D-glucose + [EMIm]ESO4+water solutions. The V φ values were used to calculate the standard partial molar volumes, $V_{\phi}^{0}$ , and transfer volumes, $\Delta_{\mathrm{tr}}V_{\phi}^{0}$ , of D-glucose from water to aqueous ionic liquid solutions. These volumetric parameters, for all the solutions studied, are positive and increase monotonically with increasing the concentration of [EMIm]ESO4. These observations have been interpreted in terms of the interactions between D-glucose and ionic liquid in the aqueous solution. The viscosity data were analyzed in terms of the Jones-Dole equation to determine the values of the viscosity B-coefficients. The calculated conductometric parameters, the limiting molar conductivities, Λ 0, the association constants, K a, and the Walden products, Λ 0 η, for [EMIm]ESO4, decrease with increasing concentration of D-glucose. This trend suggests that the ions of an ionic liquid do not have the same hydrodynamic size in the presence of D-glucose molecules (ILs) and consequently provides evidence for the dehydration effect of the ionic liquid in aqueous D-glucose solutions.
