Abstract: The ultrasonic absorption has been measured at different frequencies 1 MHz to 10 MHz in the binary liquid mixtures of methanol with cinnamaldehyde and acrylonitrile over the entire range of composition and at five different temperatures 293 K, 298 K, 303 K, 308 K and 313 K. The result has been used to discuss the nature and strength of intermolecular interactions in the system. In these systems structural relaxation plays a predominant role over thermal relaxation process. The increase or decrease in ultrasonic absorption with increase in molar concentration is due to the possible structural relaxation process in these binary liquid mixtures. These studies may be important because of their extensive use in the engineering, process industries, textile industries, pharmaceutical industries and nuclear energy industries
