|Title:||Dielectric relaxation studies of ternary liquid mixtures of aniline and substituted anilines with acrylonitrile in the microwave region|
Frequency domain technique
|Abstract:||Dielectric behaviour of three amines and their mixtures: N-methyl aniline + acrylonitrile, aniline+ acrylonitrile and N, N-dimethyl aniline + acrylonitrile at microwave frequency 9.36GHz has been studied at temperature 303K. Different dielectric quantities like dielectric constant (ε<sup>׳</sup>), dielectric loss (ε<sup>״</sup>), static dielectric constant (ε<sub>o</sub>), and dielectric constant at optical frequency (ε<sub>∞</sub>) have been determined. The relaxation time (τ) has been calculated by both Higasi’s method and Cole-Cole method. The molar free energy of activation (Δ<i style="">F</i><sub>τ</sub>) and (Δ<i style="">F</i><sub>η</sub>) have also been calculated. The complex systems studied show the maximum relaxation time values at 1:1 complex ratio by both Higasi’s method and Cole-Cole plot method.|
