Thermo Acoustic Study Of Benzamide In Different Solvents At 303K

Abstract

This paper discusses an ultrasonic interferometric analysis of Benzamide in ethanol, methanol, Acetone and Diethyl ether at a temperature of 303K to understand the solute solvent interactions as well as the acoustic behaviour of the solution. Consequently, with the use of ultrasonic interferometry, we determined the velocity of sound and the other acoustic parameters in both solvents. This study shows that benzamide has different ultrasonic behaviour in pure ethanol as compared to methanol and it is caused by the variation in structural and dynamic characteristics of ethanol solvent. In particular, the ultrasonic velocity and attenuation coefficients were used to acquire information on the molecular forces and solvation processes occurring in each solvent system. The observed changes in the acoustic parameters are explained with reference to solvent polarity, hydrogen bonding and molecular interactions and gives a scientific insight of the molecular interaction of benzamide with ethanol and methanol at a specific temperature. These results should therefore prove useful with regard to the best means of employing benzamides in a variety of industrial and scientific processes.
