Abstract

Isothermal vapor-liquid equilibrium data have been measured for binary systems n-dodecane-1-defanol, n-doderane-1-dodecanol, and 1-decanoi-1-dodecanol at 140$^{\circ}C$ by using head space gas chromatography (H.S.G.C) as a static method. The activity coefficients, calculated taking into acount the nonideality of the liquid phase, were correlated with the conventional g$\^$E/ model, Margules, van Laar, Wilson, NRTL equations. These equilibrium data were thermodynamically consistent by Rrdlich- kister test, among these data, system n-dodecane-1-detanoi has minimum azeotrope.

n-dodecane-1-decanol, n-dodecane-1-dodecanol 및 1-decanol-1-dodecanol계 의 14$0^{\circ}C$ 등온 기액평형 데이타를 static method로써 Head Space Gas Chromatography (H.S.G.C)를 이용하여 측정하였다. 액상의 비이상성을 고려하여 계산된 활동도계수는 Margules, Van Laar, Wilson, NRTL g$^{E}$ 모델을 이용하여 상관관계를 구하였으며, Redlich-Kister의 열역학적 일치성 시험을 통해 데이타의 신빙성을 확인하였다. 측정한 이성분계중 n-dodecane-1-decanol계는 최소 공비점을 가짐을 알 수 있었다.
