Ultrasonic attenuation measurement in the mixture of cyclohexane and methanol

Abstract

Ultrasonic technique is a powerful tool for the study of inter and intra-molecular interactions in a mixture. It is a non-destructive testing tool. Low amplitude ultrasonic propagation, as is used for the present work, does not change the molecular structure of a liquid. This technique is the most preferred one as it will not allow local heating. Liquid mixtures behave critically with the change in temperature and concentration in any of the component. In the present work, physical properties of mixture of cyclohexane and methanol are studied using ultrasonic pulse echo technique. Ultrasonic attenuation is measured to study mixture of cyclohexane and methanol. Present system is operated at 5 MHz frequency and the mixture is studied in the controlled temperature environment by using Thermostat (Julabo F32) with an accuracy of ±0.10C. Non-linearity in ultrasonic attenuation with maxima and minima is observed due to concentration fluctuations in the given mixture.
