VOLUMETRIC, ACOUSTIC, OPTICAL, AND VISCOMETRIC PROPERTIES OF BINARY-MIXTURES OF 2-METHOXYETHANOL WITH ALIPHATIC-ALCOHOLS (C1-C8)

Densities, refractive indexes, speed of sound data, and viscosities of 2-methoxyethanol + alcohol mixtures are determined at 298.15, 303.15, and 308.15 K. Density results are used to calculate excess molar volume. The results of speed of sound data, refractive index, and viscosity are used to calculate the changes in isentropic compressibility, molar refractivity, and viscosity. These properties are fitted to the Redlich-Kister type equation. Intermolecular interactions in mixtures of 2-methoxyethanol with alcohols have led to rather widely varying excess molar volumes from negative to large positive values, depending on the size of the alcohols. McAllister's three-body-interaction model is used to correlate the binary kinematic viscosities, and results are compared with those from Lobe's relation. Furthermore, speed of sound data for mixtures are calculated from the theoretical relation of Auerbach.
