Liquid - liquid equilibria data for musk ketone , musk xylene , dimethyl sulfoxide ( or acetonitrile ) and heptane ( or cyclohexane ) quaternary systems were measured firstly to evaluate the effect of the two liquid phase on the separation of musks mixture 摘要本文计算并测定了酮麝香、二甲苯麝香、二甲基亚砜(或乙腈)和庚烷(或环己烷)四元体系的液液相平衡,试验结果与计算值基本吻合。
The liquid - liquid equilibrium data of ternary dem - ethanol - glycerin system have been determined at atmospheric pressure and different temperatures of 20 , 40 and 60 ? c , the conjugate phase compositions and thereout the contribution curves of this ternary liquid - liquid equilibrium system have been obtained 摘要在常压, 20 、 40 、 60下,测定了二乙氧基甲烷乙醇丙三醇三元体系的液液平衡数据,得到了三元液液平衡体系的共扼相组成并由此绘得相平衡曲线。
The optimum results are gotten by simulation of changing the value of some variable such as feed position , theoretical tray . the optimum value can be used to guide industrial design . both isopropyl acetate and butyl acetate as azeotropic agent are contrast to each other according to operational data . besides , liquid - liquid equilibrium still is designed by onself , and its credibility is checked by the experimental data of the system acetic acid water - isopropyl acetate at 24 对乙酸-水-乙酸异丙酯体系和乙酸-水-乙酸丁酯体系,分别进行了进料板位置、理论板数的优化计算,得到的优化结果可用于指导工业过程的设计;对采用乙酸正丁酯和乙酸异丙酯作夹带剂时的操作进行了综合比较。
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;并求得了溶剂对溶质的选择性和分配系数。
