| Abstract: | Dielectric behaviour
of three amines and their mixtures: N-methyl aniline + acrylonitrile, aniline
+ acrylonitrile and
N,N-dimethyl aniline + acrylonitrile at microwave frequency 9.36 GHz has
been studied at temperature 303 K. Different dielectric quantities like
dielectric constant (e'), dielectric loss (e"), static dielectric constant (eo), and dielectric constant at optical frequency (e∞) 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 (ΔF ) and (ΔFη) 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. |
