Abstract

In recent years ultrasonic investigation of critical phenomena in ternary mixtures of liquids have been the subject of intensive research of both theoreticians and experimentalists. Particularly the Anomalous increase of Ultrasound attenuation near the critical region of ternary liquid mixtures has been widely studied. The experimental study of the above liquids have been carried out at 303.15 K & 308.15 K and the data can be described with its compatibility studies over a wide range of composition ranging from 0-100% of above different liquids. The result of ultrasonic velocity and its derived percentage deviation have been used to discuss the statistical approach of the blend under study. These discussion revealed that the blend is weakly polar in an ideal mixing relation. Using this data, the interaction parameters of molecular radius (r_m), molar sound velocity (R_mix) and molar volume (V_mix) were computed. The ultrasonic velocity results are further confirmed by density and percentage deviation results. For the ternary mixtures, the observed results shows that the Nomoto method seems to give good results for the evaluation and compared to Van-Dael’s method.
