The dielectric relaxation study of 2(2-alkoxyethoxy)ethanol-water mixtures using time domain reflectometry

► Complex permittivity spectra of glycol ether -water mixtures were observed. ► As composition of glycol ether in water increases the dielectric permittivity decreases. ► For pure glycol ethers two relaxation processes were observed. ► For glycol ether (MEE, EEE, BEE) the nonlinear behavior of ε0 and τ1 against XW shows heterogeneous interaction. ► Kirkwood correlation factor & excess properties confirms heterogeneous interaction.
