Isothermal vapor–liquid equilibrium (VLE) for thiophene + 2,2,4-trimethylpentane were measured at 343.15 and 353.15 K and thiophene + 2-ethoxy-2-methylpropane were measured at 333.15 and 343.15 K with a circulation still. Maximum pressure azeotropes were found in thiophene + 2,2,4-trimethylpentane systems, whereas thiophene + 2-ethoxy-2-methylpropane systems exhibit slight positive deviation from ideality. No azeotropic behavior was found in thiophene + 2-ethoxy-2-methylpropane systems. The experimental results were correlated with the Wilson model and also compared with the original UNIFAC, UNIFAC-Dortmund, and the COSMO-RS predictive models. Analyses of liquid and vapor phase composition were determined with gas chromatography. All VLE measurements passed the used thermodynamic consistency tests (integral, infinite dilution and point test).
