Abstract:
In this paper,the data of the liquid-liquid equilibrium of Water-Thioglycolate-Isopropanol Ternary System are determined at 30 ℃,40 ℃,50 ℃ and ordinary atmospheric pressure. The phase compositions and the phase equilibrium curve of this system are obtained. 30 ℃ is proved to be the best temperature for the extraction process. The experimental data are 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 are calculated,and the results show that it is entirely feasible to separate Water-Thioglycolate system by using liquid-liquid extraction technique with isopropanol as solvent.
