Based on Jacobson's molecular free length theory in lipuids and the relationstip between the ultrasonic velocity and the molecular free length in organic liquids, the equation of pressure coefficient of ultrasonic velocity in organic liquid binary mixtures is derived. The calculated pressure coefficients of ultrasonic velocity are in good agreement with the measured results.
