Interaction Study of Molecular Behavior of Mixture of Polar liquids at Microwave Frequency

Abstract

The dielectric study of tert-butyl alcohol (TB) with ethylene glycol (EG) were determined over the frequency range of 10 MHz to 20 GHz using time domain reflectometry (TDR) at temperature 55^oC for 11 different concentrations of the system. The static dielectric constant (e₀) and relaxation time (t) have been obtained by the least squares fit method. Excess properties and Kirkwood correlation factor of the mixtures have been determined. The static dielectric constants for the mixtures have been fitted with the modified Bruggeman model.
