Abstract

Density, Refractivity index and dielectric constant were measured for the binary system of Ethyl acetate with 2-methoxyethanol (2-ME), 2-ethoxyethanol (2-EE), 2-butoxyethanol (2-BE). The experiment was carried out by using Time domain Reflectometry (TDR) Technique over the wide range of frequencies from 10MHz to 20GHz at 308.15K. Dielectric permittivity (ε ׳) and dielectric loss (ε ׳׳ ) and relaxation time (τ) were measured from the TDR instrument. From the above data the molecular interaction parameters such as Bruggeman factor (fB), effective and corrective Kirkwood correlation factors (geff), (gf), Excess dielectric constant (εE), excess inverse relaxation time (1/τ)E and the thermodynamic parameter excess Helmholtz free energy of activation (ΔFE) were also calculated and the results were discussed.
