Study of dielectric behaviour of binary mixtures of cyclohexanol with cyclohexanone at ۲۹۸.۲ K

Measurement of the dielectric constant (relative permittivity) is a useful technique for characterizing molecular structure, solute-solute and solvent-solute interactions, and molecular ordering in solutions.The value of the dielectric constant is strongly related to molecular structure and intermolecular interactions [۱-۳].Relative permittivity measurements were made on binary mixtures of (cyclohexanol + cyclohexanone) for various concentrations at T = ۲۹۸.۲ K. The molecular dipole moments were determined using Guggenheim-Debye method in the temperature range of (۲۹۸.۲) K. The variations of effective dipole moment and correlation factor, g, with the mole fraction in these materials were investigated using Kirkwood-Frohlich equation
