Chemical and Physical Properties in Aqueous Solutions

Densities, viscosities, refractive indices, and speeds of sound at the temperature of 298.15 K and atmospheric pressure are reported for the binary and the miscible ternary mixtures of 2-ethoxy-2-methylpropane, ethanol, and 1-ethyl-3-methylimidazolium ethyl sulfate ionic liquid. Excess molar volumes and viscosity, molar refraction, and isentropic compressibility changes of mixing have been calculated from the physical properties. The changes of mixing have been adequately fitted to the Redlich−Kister polynomial.
