Abstract: Ultrasonic velocity and viscosity measurements, namely of TBP + methanol, TBP + ethanol, TBP + benzene, and TBP + CCl₄ have been used to study molecular interaction at 303 K. Grunberg-Nissan parameter (d), excess Gibbs energy (G^E) intermolecular free length (L_f), acoustic impedance (Z), isentropic compressibility (β), molar sound velocity (U_m), and available volume (V_a) have been calculated from these data. The excess parameters for the factors β, Z, and V_a are also evaluated. TBP-methanol and TBP-ethanol interaction leads to the formation of clusters of dissimilar molecules.
