Abstract (EN): In this work, densities, ¿, refractive indices, nD, and dynamic viscosities, ¿, of the ternary mixtures of the alcohols ethanol and 1-propanol + water with 1-ethyl-3-methylpyridinium ethylsulfate [empy][eSO 4] have been measured at T ) 298.15 K and atmospheric pressure. Excess molar volumes, VE, refractive index deviations, ¿n D, and viscosity deviations, ¿¿, have been calculated from experimental data and fitted to various correlation equations, obtaining good results. The excess properties have been used to test several prediction models, finding out that symmetric models give lower deviations than asymmetric models. © 2009 American Chemical Society.
