Thermophysical properties includingdensines, viscosities, refractive indices, and molar Conductivities for ternary systems containing D-glucose, ionic liquid {1-octyl-3-methylimidazolium bromide ([OMIm]Br)} and water have been measured at 298.15K. The density and viscosity data have been used to calculate apparent molar volumes, V-phi, standard partial molar volumes (which equal in value with infinite dilution apparent molar volume), V-phi(0), transfer volumes, Delta V-tr(phi)0, of D-glucose from water to aqueous [OMIm]Br solutions and viscosity B-coefficients. An increase in the values of V-phi(0), Delta V-tr(phi)0 and viscosity B-coefficient was observed with increase of ionic liquid concentration. Limiting molar conductivities, A(0), and ion association constants, K-a, of [OMIm]Br in aqueous D-glucose solutions were estimated from low concentration chemical model (IcCM). Molar refractions, R-D, were calculated from refractive index, no, measurements using Lorentz-Lorenz equation. All of these parameters were discussed in terms of the different solute-solvent interactions occurring between D-glucose and ionic liquid. (C) 2011 Elsevier B.V. All rights reserved.
