Dielectric Relaxation in Binary and Ternary Mixtures of Ethanol, Water, and Benzene or n-Hexane

  • H. Utzel and M. Stockhausen

The complex permittivity of the partially miscible systems ethanol-water-benzene and ethanol-water- n-hexane has been measured in the frequency range from 20 MHz to 36 GHz at 20 °C. The results are described as superposition of Debye-terms, which are considered as physically significant and are ascribed to (i) higher, ill-defined, fluctuating self- and hetero-associates (main term), (ii) associates of lower order, relaxing by rotational tumbling, (iii) free molecules. The demultimerization by benzene appears to be more effective than by hexane.
