摘要:
在常压、温度分别为30、40、50 ℃条件下,测量了1,1,2-三氯乙烷—DMF—水三元体系的液液平衡数据,得到了该三元体系的共轭相组成并绘得相平衡曲线,确定了40 ℃为合适条件.实验数据用UNIQUAC和NRTL模型进行了关联,关联值与实验值吻合良好.求得了溶剂对溶质的选择性系数,验证了以水为溶剂,采用液液萃取的方法分离1,1,2-三氯乙烷—DMF体系是完全可行的.
Abstract:
The liquid-liquid equilibrium of 1,1,2-Trichloroethane-DMF-Water ternary system was determined at 30 ℃,40 ℃,50 ℃ and ordinary atmospheric pressure,the phase compositions and the phase equilibrium curve of this system were obtained.The experimental data were correlated by using UNIQUAC and NRTL models.The agreement between calculated data and experimental data is satisfactory.The selectivity coefficients of the solvent to solutes were calculated,and the results show that it is entirely feasible to separate 1,1,2-Trichloroethane-DMF system by using liquid-liquid extraction technique with water as solvent.
