할로겐염을 포한한 액-액계에 대한 NRTL, UNIQUAC 모델의 적용(part II)
Application of NRTL and UNIQUAC Models to Liquid-Liquid System with Halogen Salts (part II)
25 ℃에서 halogen salt solution을 15 %, 25 %의 수용액으로 제조하여 benzene-halogen salt solution-n-propanol계에 대하여 용해도곡선과 tie line을 측정하였다.
Tie line data를 Eisen-Joffe식에 상호연관시켰고, NRTL, UNIQUAC, modified UNIQUAC 모델과 상호연관시켜 모델내의 parameter를 추산하고 tie line 계산치를 구하였다.
또한 염농도증가에 따른 액-액평형에 대한 염첨가 효과를 고찰하였다.
Binodal curves and tie lines were determined for benzene-halogen salt solution-n-propanol systems at 25 ℃, using halogen salt solutions prepared in the concentration of 15 % and 25 % halogen salts.
For the tie line data, the correlations were made with the Eisen-Joffe equation as well as the NRTL, UNIQUAC and modified UNIQUAC models, and the parameters in the models were estimated and the values for the tie lines calculated.
The effect of salt addition on liquid-liquid equilibria was also studied along with the increment of salt concentration.
