Dielectric properties of ethane-1,2-diol + 2-methoxyethanol + water liquid ternary mixtures

The dielectric properties of ethane-1,2-diol (1) + 2-methoxyethanol (2) + water (3) were measured in the range 30 less-than-or-equal-to t/degrees-C less-than-or-equal-to 50 and for 66 ternary mixtures covering the whole miscibility field (0 less-than-or-equal-to x1/x2/x3 less-than-or-equal-to 1). The epsilon values were analyzed by some empirical equations based on the pure-component properties for the ternaries studied. A comparison of the experimental and calculated data shows that the selected equations can be safely employed to predict the dependence of epsilon on the temperature and on the composition of the systems studied when binary and/or ternary experimental data are not available.
