Microwave Absorption and Relaxation Processes of Some Monosubstituted Benzenes and their Mixtures

Abstract

The dielectric absorption of benzene solutions of some monosubstituted benzenes and their mixtures has been studied in the microwave region over a temperature range 6 to 60 °C. The relaxation times and the thermodynamic parameters for the activated states have been determined using the measured dielectric data. The results obtained have been discussed in terms of the molecular motion of the system. The values of relaxation time for single polar component solutions are in reasonable agreement at temperatures at which there are available known data. The relaxation times for the mixtures are consistent with the results obtained by other workers for simple liquid mixtures of polar molecules in dilute solutions which they investigated.
