ii ABSTRACT The process of separating azeotropic mixtures is one of the challenging processes encountered in the chemical industry. Examples of typical methods used to separate azeotropic mixtures are azeotropic distillation and extractive distillation. However, these techniques are quite difficult since it require application of third component to alter the relative volatility of the mixture, α and additional separation unit to separate the third component from the product. Therefore, in this study, the effects of ultrasonic waves on vapor-liquid equilibrium (VLE) of normal binary and azeotropic mixtures were studied. The binary mixtures utilized were methanol-water and ethanol-water. Ultrasonic waves with frequency of 25 kHz, 40 kHz and 68 kHz were used. In terms of ultrasonic intensity, it was chosen from 50 to 250 W/A.cm 2 . Since 40 kHz is the commonly used ultrasonic frequency, the studies on the effect of different ultrasonic intensities at 50, 100, 200 and 250 W/A.cm 2 to VLE of binary mixtures were done at that frequency to obtain the best ultrasonic operating intensity. Besides that, the experimental studies were also carried out using frequency of 25 kHz and 68 kHz. The results reveal that the use of ultrasonic waves altered the α , changed the VLE data of
