Dielectric Measurements of Aniline and Alcohol Mixtures at 283, 293, 303, and 313 K Using the Time Domain Technique

Complex dielectric spectra ε*(ω) = ε‘ − j ε‘ ‘, in the frequency range 10 MHz to 10 GHz, have been determined using the time domain reflectometry (TDR) technique at various temperatures and different concentrations of alcohols, viz., ethanol, propan-1-ol, butan-1-ol, hexan-1-ol, and heptan-1-ol + aniline binary mixtures. The static dielectric constant (ε 0 ) and relaxation time (τ) have been obtained. The values of ε 0 and τ decrease with an increasing percent of aniline in the alcohol.
