Abstract

25 ℃에서 다음 3성분계, 1-1-2 trichloroethane-water-acetone, monochlorobenzene-water-acetone, cyclohexane-water-acetone, ethylacetate-water-acetone, chloroform-water-acetone, methylisobutyl ketone-water-acetone에 대한 용해도곡선을 측정하여 tie-line, plait point를 결정하였다.
Tie-line계산치를 추산하기 위하여 최소자승법을 사용하여 tie-line실험치만으로 NRTL식 중의 parameter를 결정하였다.
또한 각각의 3성분계에 대한 분배곡선, 선택도곡선을 결정하여 용매의 추출성능을 조사하였다.

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.
