摘要
用液液平衡釜测定了常压 ,60℃下加水 N-甲酰吗啉和苯、甲苯、对二甲苯、正庚烷、甲基环己烷组分间 6个拟三元体系的液液平衡 ,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模型进行了关联 ;用共轭相作图拟合法和模型参数推算法获得了各体系的褶点数据 ;
Six quasi ternary liquid liquid equilibria systems between benzene, toluene, p xylene, n heptane, methyl cyclohexane 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 equilibria systems were obtained; the experimental data were correlated using UNIQUAC and NRTL models; the plait points of these systems were obtained by the constructive fitting for the conjugate phase and parameter predicting methods; the selectivity and contribution coefficients of the solvent to the solutes were calculated.
