摘要：

Liquid-liquid equilibria (LLE) were measured at 298.15 K for three quaternary systems-hexane + heptane + toluene + sulfolane, heptane + octane + m-xylene + sulfolane and heptane + benzene + toluene + sulfolane-and for two quinary systems-hexane + heptane + toluene + m-xylene + sulfolane. and heptane + octane + benzene + m-xylene + sulfolane. The equilibrium data of these systems are compared with those predicted using the nonrandom two-liquid (NRTL) model with parameters fitted from ternary LLE data. The predicted data are in good agreement with experimental ones.
