Abstract: Theoretical results for Surface tension and excess volume were studied for the binary system formed by Benzyl alcohol + 2-Phenyl ethanol at 298.15, 308.15 and 318.15 K and atmospheric pressure over the concentration range 0.05-0.95, from the work of Ching-Ta and Chein-Hsiun Tu. Flory model,Ramaswamy and Anbananthan (RA) and model devised by Glinski, were utilized to study the association properties of strong interacting liquids. Changes in the surface tension (??) were evaluated and fitted to the Redlich-Kister polynomial to derive the binary coefficients and standard errors. Furthermore, McAllister multi body interaction model based on Eyring's theory of absolute reaction rates, has been applied. For liquid mixtures, the free energy of activation is additive, based on the proportions of the different components of the mixture and interactions of like and unlike molecules. The association behavior of the liquids was correlated with molecular interactions using the different liquid state models. Conclusively, these non-associated and associated models were compared and tested for different systems showing that the McAllister multi body interaction model yields good results as compared to associated models while Flory model shows more deviations.
