摘要:用NRTL模型对实验测定的24℃、101.33kPa下醋酸正丁酯-间苯二酚-盐水及正丁醇-间苯二酚-盐水拟三元体系的液液相平衡数据进行了关联,分别得出了醋酸正丁酯-间苯二酚-盐水及正丁醇-间苯二酚-盐水拟三元体系的模型参数,并运用模型对体系相平衡进行了预测。将实验数据与关联结果比较,结果表明:NRTL模型能较好地对以上两体系进行预测,其中对醋酸正丁酯-间苯二酚-盐水体系的预测精度较好。
The non-razadom two liquids equation (NRTL) were used to predict the phase equilibrium using th interaction parameters determined from experimental data of two pseudo ternary systems, n-butyl acetate-resorcinol salt water and n-butanol-resoreinol-sah water, at 24℃ under 101.3 kPa. It is found that NRTL used for liquid- liquid equilibrium (LLE) can provide a good prediction, of which the NRTL model worked better for the LLE dat of ternary system n-butyl acetate-resoreinol-sah water.
