The binodal curves for following ternary systems : 1-1-2 trichloroethane-water-acetone, monochlorobenzene-water-acetone, cyclohexane-water-acetone, ethylacetate-water-acetone, chloroform-water-acetone, and methylisobutyl ketone-water-acetone were determined at 25 ℃.
From these binodal curves, tie-line and plait-point were determined.
The parameters in NRTL model were determined with only experimental tie-lines by the least-squares method to predict the value of tie-lines.
The distribution and the selectivity curves were determined for ternary systems and solvents extraction effectiveness was also examined.
