Study of dielectric behaviour of ternary mixtures of anilines (N-ethyl aniline + 2-ethyl aniline + para-nitro aniline) at microwave frequency at room temperature 28℃

摘要

The dielectric behaviour of ternary system consisting of N-ethyl aniline, 2-ethyl aniline and para-nitro aniline in dilute solutions of benzene is studied at 9.920 GHz at room temperature (28℃). Different dielectric parameters including dielectric constant ε′ dielectric loss ε″, dipolemoment μ and relaxation times T_0, T_((1)) and T_((2)) for three different compositions of the ternary system are determined using measured data. The experimental T_0 values for three ternary mixture compositions are compared with the values predicted by different theoretical relations.
