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