Study of Dielectric and Acoustic Properties of Binary Liquid Mixtures of Cyclohexane with n-Butanol at 308 K

Present paper deals with study of dielectric constant, density and ultrasonic velocity and derived properties for the binary mixtures of cyclohexane and n-butanol over the entire concentration range measured at 308 K. The experimental data were further used to calculate derived parameters like Bruggeman factor, Gibbs free energy, enthalpy of activation, compressibility, and acoustic impedance, molecular free length, inverse relaxation time and excess parameters. The values of excess properties were further fitted with Redlich-Kister polynomial equation to estimate the binary coefficients and standard deviation. The resulting excess functions were interpreted in terms of the interactions between the molecules in the binary mixtures. Results confirm that weak bonded intermolecular interaction takes place between cyclohexane and n-butanol.
