Study of the Solution Properties of Ternary Mixtures of 1,3-Dioxolane (1), Diethyl Ether (2), and n-Amyl Alcohol (3) and the Corresponding Binary Mixtures by Density, Viscosity, Refractivity, and Ultrasonic Speed Measurements at 298.15 K
The excess molar volume (V(E)), viscosity deviation (Delta eta), deviation in isentropic compressibility (Delta K(s)). and excess molar refractivity (Delta R) have been investigated using experimentally measured densities, viscosities, speeds of sound, and refractive indices for the three binary mixtures 1,3-dioxolane (1) + diethyl ether (2), diethyl ether (1) + n-amyl alcohol (2), and 1,3-dioxolane (1) + n-amyl alcohol (2) and the corresponding ternary mixture 1,3-dioxolane (1) + diethyl ether (2) + n-amyl alcohol (3) at 298.15 K. The calculated quantities were further fitted to the Redlich-Kister equation to estimate the binary fitting parameters and standard deviations from the regression lines. The excess or deviation properties were found to he either negative or positive depending on the molecular interactions and the nature of the liquid mixtures.
