Dielectric relaxation study of 2 and 3-chloroaniline and 2 and 3-methoxyaniline with 1,4-dioxane mixtures using time domain technique

► The frequency dependence dielectric permittivity ε′ and dielectric loss ε″ of 2-CA, 3-CA, 2-MA and 3-MA with DX at 25 °C were observed. ► Relaxation time (τ) increase with increase in volume fraction of aniline in DX. ► Kirkwood factor, excess dielectric constant and Bruggeman factor were determined for aniline-DX mixtures.
