Liquid-Liquid Equilibria of Azeotropic Ternary Mixtures

초록

Entrainer로써 각각 ethyl acetate, N-propyl acetate, N-butyl acetate를 포함하며 공비혼합물을 형성하는 물-초산-entrainer의 삼성분계에 대하여 25℃와 40℃에서 적정법과 cross-section method를 이용하여 용해도 곡선과 tie-line을 결정하였다. 또 이들 액-액 평형 실험결과들을 UNIQUAC model을 이용하여 잘 correlation 할 수 있었고 물과 초산의 이성분계짝의 UNIQUAC parameter 들은 entrainer의 종류에는 별 영향이 없으나 상분리가 일어나는 온도에는 민감함을 보였다.

For the azeotropic ternary systems which contain water, acetic acid, and either ethyl acetate, or N-propyl acetate, or N-butyl acetate as the entrainer, the binodal curves and the tie-lines are, respectively, determined using the titration method and the cross-section method at 25℃ and 40℃. With the UNIQUAC model, these experimental equilibrium data are correlated with good accuracy. The UNIQUAC parameters for the binary pair of water and acetic acid are almost entrainer-independent. However those model parameters appear to be influenced by the temperature of phase separation to a considerable extent.
