摘要：

Liquid-liquid equilibrium (LLE) data were measured at 298.15 K and atmospheric pressure for six ternary systems: n-hexane+benzene+sulfolane, n-hexane+toluene+sulfolane, n-hexane+xylene+sulfolane, n-octane+benzene + sulfolane, n-octane + toluene + sulfolane, n-octane + xylene + sulfolane; three quaternary systems : n-hexane + n-octane + benzene + sulfolane, n-hexane + benzene + toluene + sulfolane and n-octane + toluene + xylene + sulfolane; one quinary system : n-hexane + n-octane + benzene + toluene + sulfolane. The equilibrium data of ternary systems were used to regress interaction parameters in non-random two-liquid (NRTL) equation. These parameters were directly used to predict equilibrium data of quaternary and quinary systems. The predicted data are in good agreement with experimental data. (C) 2000 Elsevier Science B.V.
