Abstract: The dielectric relaxation and dipole moment of different concentration binary mixtures of mono methyl, mono ethyl and mono butyl ethers of ethylene glycol with four polar solvents i.e. ethyl alcohol, glycerol, dimethyl sulphoxide and dimethyl formamide have been measured in dilute solutions of 1,4-dioxane at 35°C. The measured values of permittivity (') and dielectric loss ('') at 10.1 GHz, static dielectric constant (o) at 1 MHz and high frequency limiting dielectric constant () have been used to determine the values of molecular relaxation time ( o), and dipole moment ( ) of the different composition binary mixtures. The analysis of the results based on hetero-association in these binary systems, indicates the existence of different characteristic heterogeneous species in dilute solutions. The comparative values of o and of the various binary mixtures of different composition also suggest that the nature of heterogeneous interaction varies with the type of polar solvent and also constituents composition in the binary mixture.
