The relative permittivities (ϵ) of 1,2-ethanediol, 1,2-dimethoxyethane, and nine binary mixtures were measured at five temperatures from -10 to +30 °C. The experimental data were fitted vs composition of the mixture (x1) in order to investigate the existence of solvent/cosolvont complexes, their stoichiometric ratios, and their thermostability. The formation of these complex species may be interpreted on the basis of specific interactions between the components of the mixed solvents. © 1992, American Chemical Society. All rights reserved.
