| Abstract: | The ternary system of liquid liquid phase equilibrium has been studied at 25 ℃ in this paper.The separation cure of the system was determined by the turbidity method,The tie line data were obtained by analyzing the acetic acid concentration of both phases at equilibrium. The experimental results showed that the mixed extractant was a good extractant. |
