Chemical and Physical Properties in Aqueous Solutions

The viscosities and densities of the ternary mixtures water + ethyl acetate + ethanol and their constituent binaries have been measured at 298.15 and 318.15 K and atmospheric pressure. The excess molar volumes, , and viscosity deviations, Δη, were calculated from density and viscosity, respectively. A rational function due to Myers and Scott was used to describe the composition dependence of these properties. To describe the ternary system, binary pair additivity and the Pando et al. rational functions for the ternary contributions (ΔηT and ) were considered.
