- 中文摘要: The dielectric behaviour of 1,2-propanediol was investigated to understand the effect of the hydroxyl group on the dielectric parameters. The measurement of permittivity e¢ and e2 of 1,2-propanediol was carried out in the frequency range 10 MHz to 20 GHz at 25 °C temperature. Static permittivity and dielectric relaxation time are extracted from a 1,2-propanediol-water mixture using the bilinear calibration method and non-linear least squares fit method. Calculated Kirkwood correlation factor contains information regarding solute-solvent interaction. The hydrogen bonded model suggested by Luzar is applied to determine the molecular parameters. The excess dielectric parameters and Bruggeman factor show the systematic change in the dielectric parameter of the system with change in concentration.
