Abstract
The complex permittivity spectra of binary liquid mixtures of ethylene glycol mono phenyl ether (EGMPE) with methanol (MeOH) were determined in frequency range of 10MHz to 25GHz using Time Domain Reflectometry (TDR) at four different temperatures 283.15, 288.15, 293.15 and 298.15K through entire concentration range. The dielectric parameters viz static permittivity (ε), high frequency limit dielectric permittivity (ε∞) and relaxation time (τ) have been obtained by CNLS fit method. From the experimental data, parameters such as excess static permittivity (εE), excess inverse relaxation time (1/τ)E, Kirkwood correlation factor (gf), effective Kirkwood correlation factor (geff) and Bruggeman's factor (fb) and some thermo-dynamical parameters have been calculated. Excess parameters were fitted to the Redlich–Kister type polynomial equation.
