THEORETICALLY EVALUATING THE FORMATION OF HYDROPHOBIC CLUSTERS IN CERTAIN ELEMENTS USING ULTRASONIC FREQUENCY

Particularly the anomalous increase of ultrasound attenuation near the critical region of binary liquid mixtures has been widely studied. The solutions have been carried out at some temperature range with the frequency range of about 200 Hz/sec. The data can be described quantitatively in terms of the Relaxation process, which can be approximated as Ideal solutions. In the case of ethyl alcohol & Dioxane, all of the ultrasonic data are consistent with the formation of intermolecular Hydrogen bonding associated with thermodynamic and kinetic constants. The results are discussed together with corresponding data for the above solution from previous works. It was concluded that for the solvent effects in an aqueous alcohol binary mixture are limited almost entirely to the hydrophobic ground-state stabilization by the organic co-solvent. This can be evaluated in pure water with “hydrophobic” clusters of hydrocarbon portion of 1,4 Dioxane. The composition dependence of absorption is analyzed in the light of Gordon G.Hammes theory together with Eigen & Maeyer's solution model.
