Ultrasonic Studies on Binary Mixtures of Trichloro Ethylene with 1-Hexanol at Room Temperature

Ultrasonic studies find extensive use in the studies of the behavior of liquids and liquid mixtures as these help in the determination of many thermodynamic properties in addition to indicating the presence of specific interactions.

Recently with the introduction of ultrasonic waves into variety of applications like acoustic microscopy, medical probing, non-destructive evaluating calculation etc., good acoustic medical processing, low ultrasonic velocity and absorption have been necessitated. The study of ultrasonic propagation in binary liquid systems has taken a new turn from conventional one. The interest now shifted to liquid mixtures possessing low ultrasonic velocity and low attenuation. Various thermo acoustic parameters of the binary mixtures of Trichloroethylene with the selected liquid were calculated by using experimental quantities such as ultrasonic velocity, density, viscosity. The work forms part of an overall program of investigation on the application of ultrasonic velocity to understand the nature of molecular interaction in a binary liquid mixture using trichloroethylene as a common component. One aromatic hydrocarbon has been chosen for this investigation.

Ultrasonic velocity in binary mixtures with a detailed description along with the experimental details for the measurement of ultrasonic velocity using interferometer of 2MHz. It is presented in this thesis. It also presents the Experimental Techniques and theoretical consideration relating to the measurement of density by specific gravity bottle method. The Experimental method for the measurement of viscosity adopting Oswald's Viscometer at room temperature (303.15K) is also included. It also describes the theoretical considerations and various standard equations used for evaluating several parameters and their excess quantities. The results are published in the light of earlier results.
