چکیده انگلیسی


• Isothermal VLE data of the binary mixtures n-heptane + chlorobutane isomers are reported.
• VLE data have been correlated with the Wilson equation.
• Thermodynamic consistency of VLE data was checked by the van Ness method.
• The calculated excess Gibbs energies were positive for all the mixtures.
• UNIFAC and VTPR methods were used to predict the phase equilibrium.

The study of the isothermal vapour–liquid equilibrium (VLE) of the binary mixtures n-heptane plus chlorobutane isomers (1-chlorobutane, 2-chlorobutane, 1-chloro-2-methylpropane or 2-chloro-2-methylpropane) at three different temperatures, T = 288.15, 298.15 and 308.15 K, is presented in this contribution. The experimental results were correlated using Wilson equation and the thermodynamic consistency of the data was checked by the van Ness method. Furthermore, two different methods have been used to predict the phase equilibrium in isothermal conditions: a pure group contribution method (modified-UNIFAC) and a group contribution equation of state (VTPR).
