摘要：

Dielectric relaxation measurements on water-ethanolamine solvent mixtures have been carried out across the entire concentration range using Time Domain Reflectometry technique at 288 K, 298 K, 308 K, and 318 K over the frequency range from 10 MHz to 20 GHz. The mixtures exhibit a principle dispersion of the Davidson-Cole relaxation type at microwave frequencies. Bilinear calibration method is used to obtain complex permittivity epsilon*(omega) from complex reflection coefficient rho*(omega) over the frequency range 10 MHz to 10 GHz. The excess permittivity (epsilon(E)), excess inverse relaxation time (1/tau)(E), Kirkwood correlation factor (g(eff)) and thermodynamic parameters are also calculated to study the Solute-Solvent interaction.
