摘要
在常压、 6 0℃下 ,测定了加水的N 甲酰吗啉和苯、甲苯、二甲苯、甲基环己烷组分间的 3个拟三元 (四元 )体系的液 液平衡数据 ,得到了拟三元液 液平衡体系的共轭相组成和分配曲线。实验数据用UNIQUAC和NRTL模型进行关联 ,分别得到了拟三元和四元体系的模型参数。同时用共轭相作图法和模型参数推算了各体系的褶点数据 。
Three quasi ternary (vs quaternary) liquid liquid equilibrium systems between benzene, toluene, p xylene, methylcyclohexane and N formylmorpholine(NFM)+water have been determined at normal pressure and 60 ℃, the conjugate phase compositions and the contribution curves of these quasi ternary liquid liquid equilibrium systems were obtained. Experimental data were correlated by using UNIQUAC and NRTL models, then the model parameters of quasi ternary and quaternary systems were obtained, respectively. The plait points of these systems were obtained by the constructive fitting for the conjugate phase and parameter predicting methods, and the selectivity and contribution coefficients of the solvent to solutes were calculated.
