Liquid - liquid equilibrium data were determined for the 2
3- dichloropropylene-epichlorohydrin - water ternary system at 20. 0
30. 0
58. 3
67. 9 and 77. 4℃. The correlation of the liquid -liquid equilibrium data was done by using UNIQUAC model. In the correlation of ternary liquid -liquid equilibrium data
a mole fraction objective function was used and the model parameters were obtained. The calculated and experimental results are in good agreement.
