Volumetric, Ultrasonic and Viscosimetric Studies for the Binary Mixture (1, 4-Dioxane + Water) at T = (295.15, 298.15, 301.15, 304.15, 307.15, 310.15 and 313.15) K

Density, speed of sound and viscosity data for the binary mixtures (1,4-dioxane (1) + water (2)), were measured over the whole composition range at temperatures T = (295.15, 298.15, 301.15, 304.15, 307.15, 310.15 and 313.15) K and at the atmospheric pressure. From experimental data, the excess molar volume, isobaric thermal expansion coefficient, excess of isobaric thermal expansion coefficient, excess speed of sound, isentropic compressibility, excess of isentropic compressibility, intermolecular free-length, the excess intermolecular free-length, the viscosity deviation, the excess free Gibbs energies of activation of viscous flow, the internal pressure, excess internal pressure, acoustic impedance, the excess acoustic, and the free volume were calculated. The excess parameters were fitted by the Redlich–Kister polynomial equation to derive the coefficients and estimate the standard error values. The nature of molecular interactions between the two components of the mixture, have been discussed by means of the thermodynamic properties.
