Density, Refractive Index, Viscosity, and Speed of Sound in Binary Mixtures of 2-Ethoxyethanol with Dioxane, Acetonitrile, and Tetrahydrofuran at (298.15, 303.15, and 308.15) K

Abstract

Density, refractive index, viscosity, and speed of sound data in binary mixtures of 2-ethoxyethanol with dioxane, acetonitrile, and tetrahydrofuran are presented at (298.15, 303.15, and 308.15) K over the whole range of mole fractions at atmospheric pressure. These results are used to calculate excess molar volume, deviations in molar refractivity, viscosity, and isentropic compressibility. The calculated quantities are further fitted to the Redlich−Kister equation to estimate the binary interaction parameters and mean deviations from the regression lines. The sign and magnitude of the computed parameters are discussed to study the nature and type of intermolecular interactions in binary mixtures.

“…The effect of temperature on the index of refraction of the sample solution turns out to be a surprisingly significant issue to deal with from an experimental perspective. The temperature dependence of some common solvents – including acetonitrile – has been studied previously 28,29. Specifically, as the temperature decreases, the solvent's refractive index increases.…”

“…Mixtures containing methylcyclohexane with different liquids have also been studied [14][15][16][17]. However, no such studies were reported on the mixtures of methylcyclohexane with aliphatic alcohols.…”
