Chemical Thermodynamics and Molecular Structure

In this work, we present values of viscosity η and density ρ of ethyl alcohol + hexane, + octane, and + decane over the whole composition range at T = (273.15, 275.65, 278.15, 280.65, 283.15, 285.65, 288.15, 290.65, 293.15, 295.65, and 298.15) K and at atmospheric pressure. The deviations of viscosities (Δη) have been calculated from the experimental data. The deviations have been correlated using the Redlich−Kister polynomial equation. The viscosity results have also been correlated by Grunberg−Nissan, Teja−Rice, and Hind correlation equations.
