Dielectric Behavior of Solutions of Electrolytes in Solvents of Low Dielectric Constant. V. The Influence of Temperature and Concentration on Dielectric Properties

Dielectric loss and conductance data for octadecyltributylammonium thiocyanate in benzene show large changes in the significant frequency region of absorption and in the magnitude of conductance when the temperature is lowered from 25° to 6°C, but their variation with concentration is very similar at the two temperatures. The broad frequency range of absorption observed at concentrations in the range 0.008–0.02 molal and the failure of the change in macroscopic viscosity to account for the temperature effect suggest that a better understanding of similar systems requires more detailed examination of the interaction of the ionic and dipolar aggregates with the solvent.
