Abstract
60-75℃ 사이의 등온하에서 Cyclohexane-Alkanol(C1-C4) 혼합계의 기액평형 조성을 정적 측정방법의 일환인 head space gas chromatography(H.S.G.C)를 이용하여 측정하였다. 측정한 모든 Cyclohexane-Alkanol(C1-C4) 이성분계 혼합물에서 최소공비점이 발견되었고, 특히 Methanol-Cyclohexane계에서는 두 액상영역의 존재로 인한 minimum boiling heterogeneous azeotrope를 보였다. 실험을 통해 얻은 기액평형 데이터는 각각 gE 모델식인 Margules, van Laar, Wilson, NRTL, UNIQUAC 식 등으로 그 상관관계를 알아보았으며, 적분법 및 point-to-point test법에 의한 열역학적 일치성시험도 수행하였다.
Isothermal vapor-liquid equilibria have been measured for binary mixtures of Cyclohexane -Alkanol(C1-C4) between 60℃ and 75℃ by using head space gas chromatography(H.S.G.C), one of the static measuring methods. All the measured binary Cyclohexane-Alkanol systems have minimum boiling azeotrope, and in the Methanol-Cyclohexane system minimum boiling heterogeneous azeotrope was discovered because it has two liquid phase regions. These experimental VLE data were correlated with conventional gE models; Margules, Van Laar, Wilson, NRTL, UNIQUAC. And thermodynamic consistency is tested by the integral and point-to-point test.
