Dielectric Measurement Study of Nitrobenzene and N, N-Diethylamine in Non-Polar Medium at Microwave Frequency
Author : Nirakar S Ramteke
Abstract :
The dielectric behaviour of polar liquids like Nitrobenzene and N, N-Diethylamine in dilute solutions of non-polar solvent benzene have been studied at fixed microwave frequency 9.8 GHz (X band). Essentially each polar compound was prepared in benzene medium for few concentrations. The Dielectric constant (ε') and loss (ε") have been determined at room temperature. It is observed that dielectric constant and loss varies with concentration linearly showing the solutions were sufficiently dilute. The relaxation time and electric dipole moment of the systems is determined by a concentration variation method of Gopala Krishna based on Debye molecular model. These studies report a determination of relaxation time (τ), electric dipole moment (µ) of Polar liquids in benzene solution at room temperature.
