Abstract (EN): In this work, densities, ¿, refractive indices, nD, speeds of sound, u, and dynamic viscosities, ¿, of the ternary mixtures ethanol + water with 1-octyl-3-methylimidazolium chloride ([C8mim][Cl]) and 1-ethyl-3-methylimidazolium ethylsulfate (EMISE) have been measured at 298.15 K and atmospheric pressure. Excess molar volumes, %, refractive index deviations, ¿nD, isentropic compressibilities, kS, molar isentropic compressibilities, KS,m, isentropic compressibility deviations, ¿kS, excess molar isentropic compressibilities, KS,mE, viscosity deviations, ¿¿, and excess free energies of activation of viscous flow, ¿G*E have been calculated from experimental data and fitted to Cibulka and Singh et al. equations. The excess properties have been used to test several prediction models. © 2007 American Chemical Society.
