摘要

Densities, viscosities and ultrasonic speeds of sound for binary mixtures of 1,2-dimethoxyethane (DME) with benzene, toluene, chlorobenzene, benzyl chloride, benzaldehyde, nitrobenzene, and aniline are reported over the entire composition range at ambient pressure and temperature (i.e., T=298.15 K and p=1.01×105 Pa). These experimental data were utilized to derive the excess molar volumes ( $V_{mathrm{m}}^{mathrm{E}}$ ), excess viscosities (η E), and various acoustic parameters including the deviation in isentropic compressibility (Δκ S ), internal pressure (π I), and excess enthalpy (H E). From the excess molar volumes ( $V_{mathrm{m}}^{mathrm{E}}$ ), the excess partial molar volumes ( $overline{V}_{mathrm{m},1}^{mathrm{E}}$ and $overline{V}_{mathrm{m},2}^{mathrm{E}}$ ) and excess partial molar volumes at infinite dilution ( $overline{V}_{mathrm{m},1}^{0,mathrm{E}}$ and $overline{V}_{mathrm{m},2}^{0,mathrm{E}}$ ) were derived and discussed for each liquid component in the mixtures. The excess/deviation properties were found to be either negative or positive, depending on the molecular interactions and the nature of the liquid mixtures.
