Resumo
New isobaric vapor-liquid equilibrium data for the binary mixtures of methylcyclopentane + 2‑methylthiophene, cyclohexane + 2-methylthiophene, methylcyclohexane + 2-methylthiophene and ethylcyclohexane + 2-methylthiophene systems were determined by a modified Rose-Williams equilibrium still under the pressure of 90.00 kPa. All the vapor-liquid equilibrium data measurements passed the thermodynamic consistent test by using the Herington method and the Van Ness test, respectively. No azeotropic behavior was observed in the tested four binary systems. Meanwhile, the experimental data were correlated by the Wilson activity coefficient model and also compared with the original UNIFAC and UNIFAC Dortmund predictive models. All results demonstrated that the original UNIFAC model gave better predictions than the UNIFAC Dortmund model.
