Calculation of Mixture Equilibrium Binary Interaction Parameters in Thermodynamic Models Using Closed Cup Flash Point

In the present work, the flash points of binary systems (ethanol+ n-octane, 1-propanol+ n-octane, 1-propanol+ n-decane, and n-octane+ n-decane) were measured in atmospheric pressure. The resulting flash points data were used in NRTL, Wilson and UNIQUAC models to calculate the mixture binary parameters. The results were subsequently compared with experimentally produced VLE data, and revealed that this method is able to predict the binary interaction parameters of binary mixtures with high accuracy.
