Abstract: | Densities and surface tensions were measured for the binary liquid mixtures formed by benzonitrile, chlorobenzene, benzyl chloride and benzyl alcohol with benzene, at 298.15, 303.15 and 313.15 K and atmospheric pressure, over the whole composition range. The Prigogine?CFlory?CPatterson model (PFP), the Ramaswamy and Anbananthan (RS) model, the model derived by Glinski, the Sanchez equation, the Goldsack relation and Eberhart??s model were used to predict the associational behavior of weakly interacting liquids. The measured properties were fitted to the Redlich?CKister polynomial equation to estimate the binary coefficients and standard errors. Furthermore, the McAllister multi-body interaction model was also used to correlate the binary solution properties. These non-associated and associated models were compared and tested for different systems, showing that considering the association processes yields better agreement between theory and experiment as compared to non-associated processes. |
