Dielectric and thermodynamic behavior of binary mixture of anisole with morpholine and aniline at different temperatures

摘要

The interaction between the molecules of anisole with morpholine and aniline was studied at static frequency. Static permittivity at three different temperatures was computed for the mixture of anisole with morpholine and aniline. Permittivity at static frequency and at optical frequency was measured at different concentrations of the mixtures at different temperatures and they were used to calculate dielectric parameters such as Kirkwood correlation factor, excess permittivity, Bruggeman parameter, and thermodynamic parameters (Gibbs free energy). These parameters were used to carry out temperature dependent dielectric studies on the mixtures. The investigation showed a systematic change in dielectric parameters of the systems with the change in concentration and temperature. (C) 2007 Elsevier B.V. All rights reserved.
