Abstract
Theoretical velocities of binary liquid mixtures of anisaldehyde with toluene at 303.15, 308.15, 313.15 and 318.15 K have been evaluated by using theoretical models of liquid mixtures such as Nomoto, Van Dael-Vangeel, Schaff’s collision factor theory and Junjie’s relations. Density and ultrasonic velocity of these mixtures have also been measured as a function of concentration and temperature and the experimental values are compared with the theoretical values. A good agreement has been found between experimental and Nomoto’s theoretical ultrasonic velocities. The results are explained in terms of intermolecular interactions occurring in these binary liquid mixtures.
Highlights
Ultrasonic velocity in a medium is related to the binding forces between the molecules
Ultrasonic velocities in liquid mixtures consisting of polar and non-polar components are of considerable importance in understanding the intermolecular interaction between component molecules and find applications in several industrial and technological processes[1,2,3]
The ultrasonic velocities of the chosen binary liquid mixture at 303.15, 308.15, 313.15 and 318.15 K over the entire range of composition have been evaluated by using various theories and compared with the experimental values
Summary
Ultrasonic velocity in a medium is related to the binding forces between the molecules. Ultrasonic velocities in liquid mixtures consisting of polar and non-polar components are of considerable importance in understanding the intermolecular interaction between component molecules and find applications in several industrial and technological processes[1,2,3]. Several researchers[4,5,6,7] carried out ultrasonic investigations on liquid mixtures and correlated the experimental results with the theoretical relations of Nomoto[8], Van Dael and Vangeel[9], Schaff’s10 and Junjie’s11 equations and interpreted the results in terms of molecular interactions.
