Densities, viscosities, refractive index, dielectric constant (ε') and dielectric loss (ε") of 2,3-dichloroaniline (2,3-DCA) + 2-methoxyethanol (2-ME) for different mole fractions of 2,3-dichloroaniline in binary mixture have been measured at single microwave frequency 10.985 GHz at 40 oC by Surbers technique at microwave X-band. The values of dielectric parameters (ε') have been used to evaluate the molar polarization (P12), loss tangent (tan δ), excess viscosities (Δη) and excess dielectric constant (Δε') have also been estimated. 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 (tan δ), molar polarization (P12) varies non-linearly but activation energy (Ea), viscosity (η), density (ρ) and refractive index (n) varies linearly with increasing mole fraction in binary mixture of 2,3-dichloroaniline (2,3-DCA) + 2-methoxyethanol (2-ME). Hence, solute-solvent molecular associations have been reported.
