Isobaric vapor-liquid equilibrium (VLE) for three systems with different organic sulfur compounds (1-propanethiol + toluene, thiophene + toluene, and diethyl sulfide + toluene) were measured at 90.03 kPa with a circulation still. The experimental results were compared with original UNIFAC, UNIFAC-Dortmund, and COSMO-RS predictive models. All systems showed nearly ideal behavior. VLE data sets measured passed the point consistency test.
