In this work, influence of the ionic liquid, 1-hexyl-3-methylimidazolium bromide [HMIm]Br, on the thermodynamic properties of aqueous sucrose solutions has been investigated. For this purpose, density, speed of sound and viscosity measurements have been carried out for this system at temperatures T = (288.15 to 318.15) K and atmospheric pressure. Thermophysical parameters including the standard partial molar volume 4, transfer volume of sucrose from water to aqueous ionic liquid solutions Delta V-tr(Phi)0, partial molar isentropic compressibility kappa(0)(Phi) and viscosity B-coefficient have been calculated using the measured experimental data. From the obtained parameters, some information in regard with the solute-solvent interactions in the studied systems was obtained. The cosphere overlap model was used to interpret the positive transfer volume Delta V-tr(Phi)0. The scaled particle theory has been used to confirm the obtained results. (C) 2015 Elsevier Ltd.
