Abstract :
Complex Dielectric spectra of Methyl acetate (MA) with 2-Alkoxyethanols like 2-methoxyethanol (2-ME), 2-ethoxyethanol (2-EE), 2-butoxyethanol (2-BE) for various concentrations over the frequency ranges from 10MHz to 20GHz at 308.15K were recorded using Time Domain Reflectometry (TDR). The dielectric constant, dielectric permittvity and dielectric loss were obtained from the TDR measurement. The molecular interaction parameters like relaxation time, Kirkwood correlation factors, Bruggeman factor, excess dielectric constant, excess inverse relaxation time and excess Helmholtz free energy of activation were also calculated. This study gives the information about the nature of molecular interaction between the participating liquid molecules.
