Temperature Dependent Thermo-Acoustic and Molecular Interaction Studied of Methyl Propyl Ketone and 1-Butanol Binary Mixtures
Abstract: The Density (ρ), refractive index (nD), viscosity (?) and ultrasonic velocity (U) of pure components Methyl Propyl Ketone (MPK), 1-Butanol and their binary liquid mixtures, have been determined as functions of composition at different temperatures (T=303.15 K,313.15 K, and 323.15 K) at a fixed frequency of 2 MHz over a different concentration ranges. The values of adiabatic compressibility (?ab), intermolecular free length (Lf), acoustic impedance (Z), free volume (Vf), relaxation time (?), were computed using experimental data at different temperature. The observed behavior of these parameters concerning different compositions have been discussed in terms of their molecular interactions between the unlike molecules of the binary mixtures. Also, the thermodynamic parameters such as Gibb's free energy (G), Wada's constant (W) Rao's constant (R) and various excess parameters calculated. The variation in these parameters has been discussed in terms of nature and strength of molecular interactions at varying temperature with composition of liquid mixtures.
Keywords: Ultrasonic velocity, acoustic parameters, excess parameters
