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.
