Ultrasonic speed and density have been measured at 303K-318K in ternary system of (di-(2-ethyl hexyl) phosphoric acid) of dehpa with cyclohexane andethanol mixed solvent over entire composition range. The acoustical parameters such as adiabatic compressibility (Ks), free length (Lf), acoustic impedance (Z), Relative association (RA), wada’s constant (W), molar volume (Vm), interaction parameter ( χ ), surface tension ( σ ), Rao's constant (Rm) and also excess parameters such as excess adiabatic compressibility (KEs), Excess velocity (CE), Excess free length LEf , Excess molar volume (VEm )and Excess acoustic impedance(ZE) are computed for the ternary mixture at different temperatures. The results are discussed in terms of molecular interaction between the components of the ternary mixture. Calculated excess values indicate that both strong and weak molecular interaction prevailing in the system which basically depend upon concentration. The ultrasonic velocities calculated using various theoretical models and validity of these theoretical relations have been discussed in the present system.
