The relative permittivities epsilon for the ternary 1,2-ethanediol (component 1) + 2-methoxyethanol (2) + water (3) solvent system have been measured for 66 mixtures covering the whole mole fraction composition 0 less-than-or-equal-to X1/X2/X3 less-than-or-equal-to 1 range at -10, -5 and 0-degrees-C.

Abstract
The relative permittivities epsilon for the ternary 1,2-ethanediol (component 1) + 2-methoxyethanol (2) + water (3) solvent system have been measured for 66 mixtures covering the whole mole fraction composition 0 less-than-or-equal-to X1/X2/X3 less-than-or-equal-to 1 range at -10, -5 and 0-degrees-C. The experimental data were used to test some empirical relations stating the dependence of epsilon = epsilon (X1, X2, X3). A comparison between the calculated and experimental data show that these equations can be usefully employed to predict epsilon values in correspondence of the experimental data gaps.
