Computational analytical study in (O-Anisidine + Propyl Acetate) mixture through thermo-acoustical excess parameters and redlich-kister coefficients

Abstract The analysis involved in the present study of excess acoustical parameters and their Redlich-Kister Coefficients at different temperatures range from 303.15 K to 318.15 K with variation of 5 K temperature interval for each study and all these are explained in liquid mixtures containing functional materials namely (O-Anisidine mixed with Propyl Acetate). The obtained excess values of acoustical parameters namely Gibb’s free energy (G*E), enthalpy (HE) and internal pressure (πE) have been computed from measured experimental data. The results have also been helpful to obtain Redlich-Kister coefficients from polynomial equation and also to obtain their deviations.
