Dielectric Behaviour of Binary Mixture of 2-Chloroaniline with 2-Methoxyethanol at 30°C Using Microwave Frequency

Abstract

Densities, viscosities, refractive indices, dielectric constant (ε') and dielectric loss (ε'') of 2-Chloroaniline (2-CA)+2-Methoxyethanol (2-ME) for different mole fractions of 2-CA in binary mixture have been measured at single microwave frequency 10.985 GHz at 30°C by Surber method using microwave X-band. The dielectric parameters ε' and ε'' have been used to evaluate the molar polarization (P 12 ) loss tangent (tanδ), viscosity (η), activation energy (Ea).These parameters have been used to explain the formation of complexes in the system. It is found that dielectric constant (ε'), dielectric loss (ε''), loss tangent (tanδ), molar polarization (P 12 ) varies non-linearly but activation energy (Ea), viscosity (η), density (ρ), and refractiv index (n) varies linearly with increasing mole fraction in binary mixture of 2-Chloroaniline 2-CA+2-Methoxyethanol 2-ME. Hence, solute-solvent molecular associations have been reported.
