- 中文摘要: The data obtained for density, viscosity, and dielectric constant are used for the study of the physical properties of 2-ethoxy ethanol-water mixtures. Density measurements showed the presence of contraction in the volume of the mixture and also in partial molal volume of the components. Viscosity data provided supporting evidence of interaction between the two solvents. The dielectric data for the system were studied in terms of a deviation fraction, .DELTA.D , representing the deviation from an ideal volume mixture. The results are also comparaed with the data obtained in the literature for water-2-methoxy ethanol and water-ethylane glycol mixtures.
