Abstract : 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 文摘:用液液平衡釜測定了常壓， 60下加水n -甲酰嗎啉和苯、甲苯、對二甲苯、正庚烷、甲基環己烷組分間6個擬三元體系的液液平衡，得到了擬三元液液平衡體系的共軛相組成和分配曲線；實驗數據用uniquac和nrtl模型進行了關聯；用共軛相作圖擬合法和模型參數推算法獲得了各體系的褶點數據；并求得了溶劑對溶質的選擇性和分配系數。 |
