Description
Summary:Microwave dielectric study for the binary mixtures of ethyl acetate with propylene glycol was performed over the frequency range of 10 MHz –20 GHz and in the temperature range of 288 K to 318 K using time domain reflectometry technique. Dielectric parameters such as static dielectric constant (εs), relaxation time (τ), excess dielectric constant (εs)E, excess inverse relaxation time (1/τ)E, Kirkwood correlation factor (geff), Bruggeman factor (fB) and thermodynamic parameters viz. molar enthalpy of activation, molar entropy of activation were also determined. Variation of measured dielectric and thermodynamic parameters have been used to explain the intermolecular interactions between the ethyl acetate and propylene glycol.
