Ultrasonic speed and density have been determined in Dehpa (Di(2-ethyl-hexyl) phosphoric acid), n-Butyl Bromide and their mixtures at four temperatures 303K, 308K,313K, 318K over entire composition range. Different acoustic parameters and their excess values were calculated using measured value of ultrasonic velocity and density at different temperatures and have been discussed to highlight the type and extent of molecular interaction between component molecules and to reflect effect of temperature on them. Further theoretically ultrasonic speeds calculated using various theoretical models and empirical relations and validity of these theoretical approaches have been tested for the present system.
