Temperature dependent dielectric relaxation study of 2-butanol-water mixtures from 10 MHz to 30 GHz
A study has been made to investigate the Hydrogen bond interaction between binary mixtures of 2-Butanol and water using Time Domain Reflectometry technique (TDR). Various volume concentrations of 2-Butanol-water have been used in the frequency range of 10MHz to 30GHz at 0 to 20°C. Complex permittivity spectra for 2- Butanol-water mixtures determined which shows a Debye type of behavior. Dielectric parameters i.e. dielectric constant (εo), relaxation time (τ) obtained using least square fit method. Using the fundamental properties Kirkwood correlation factor, Bruggeman factor, excess dielectric properties and thermodynamic properties were also been determined to study the interaction between regular dipole interaction of hydrogen-Bonded (H-bonded) liquids the mixtures.
