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