Ultrasonic velocities (U), viscosities (η) and densities (ρ) of binary liquid mixtures of di–(2-ethylhexyl) phosphoric acid (DEHPA) with eight non polar diluents viz. n-pentane, n-hexane, n-heptane, benzene, carbon tetrachloride, cyclohexane, carbon disulphide and dioxane are measured at temperature 303.16 K and 0.01MPa for entire range of concentration. The measured data are used to compute acoustic impedance (Z), isentropic compressibility (βs), intermolecular free length (Lf), free volume (Vf), internal pressure (∏i) and viscous relaxation time(τ). The excess properties are also evaluated from the measured data to study inter-and intra-molecular interaction between components of liquid mixtures. The research findings may be utilized in solvent extraction process to enhance extraction efficacy. © 2020 by the authors.
