Dielectric Relaxation of Propan-1-ol with Chlorobenzene, 1,2-Dichloroethane, and Dimethylene Chloride at (288, 298, 308, and 318) K Using Time-Domain Reflectometry Technique

The values of complex permittivity of molecules containing chlorine with propan-1-ol binary mixtures have been determined over the frequency range of (0.1 to 20) GHz, at temperatures of (288, 298, 308, and 318) K, using the time-domain reflectometry (TDR) method for 11 molalities of each molecule containing chlorine with propan-1-ol system. The dielectric relaxation in these systems can be described by a single relaxation time using the Havriliak and Negami model. The static dielectric constant (ε 0 ) and relaxation time (τ) have been obtained by fitting experimental data with the Havriliak−Negami equation.
