Present research work covers the observation of molecular interaction between the binary mixture of Triethyl silicol Ethylether and Ethanol on the basis of acoustic and thermodynamics properties of the mixture. In this work with the help of experimental values of Ultrasound velocity, density and Viscosity other acoustic and thermodynamics properties like Isentropic Compressibility (βs), Specific Acoustic Impedance (C.G.S.), Molar and available Volume,Intermolecular free length (L_f), Ultrasound velocity (V), Density (ρ), Excess Viscosity (η), Shear’s Relaxation Time (τ_s) have been computed at different temperature(30°C,40°C). In each case negative values of β_s^E, V_m^E, V_a^E and positive value of η^E indicates the strong interaction between the components of the mixtures. While positive values of β_s^E, V_m^E, V_a^E and negative value of η^E decide the weak interaction between the liquid molecules due to dispersion forces. The ultrasound velocity and density increase on increasing mole fraction of triethyl silicol, but both decreases on increasing temperature. Other parameters like Specific Acoustic Impedance, Shear Relaxation Time (τ_s) and Rao’s Constant(R) support the specific interaction between the molecules with observations of negative excess of Isentropic Compressibility and positive viscosity.The Result has been interpreted in terms of plots and graphs.
