초록

Water+n-methylformamide(NMF), benzene+NMF 그리고 toluene+NMF의 353.15 K 이성분계 등온 기-액상평형을 headspace gas chromatography(HSGC)로 측정하였고, NMF+benzene+n-heptane과 NMF+toluene+n-heptane 삼성분계에 대한 298.15 K 액-액상평형을 tie-line 측정법으로 결정하였다. 이성분계 기-액상평형 데이터는 공비점이 없었으며, $g^E$ 모델식(Margules, van Laar, Wilson, NRTL, UNIQUAC)에 비교적 작은 편차로 잘 상관되었다. 삼성분계 tie-line 데이터는 NRTL식과 UNIQUAC식을 이용하여 상관과 추산을 병행하였으며, Hirata-Fujita식과 Maior-Swenson식을 이용하여 정확도를 검증하였다.

Binary isothermal vapor-liquid equilibrium(VLE) data were measured for water+n-methylformamide(NMF), benzene+NMF and toluene+NMF systems by using headspace gas chromatography(HSGC) at 353.15K. Additionally, the ternary liquid-liquid Equilibrium(LLE) data were determined by measuring of tie-line for the systems of NMF+benzene+n-heptane and NMF+toluene+n-heptane at 298.15 K. The measured isothermal binary VLE data have no azeotropes and were correlated well with $g^E$ model equations of Margules, van Laar, Wilson, NRTL and UNIQUAC. The experimental ternary tie line data were also correlated well with NRTL and UNIQUAC models. Besides their accuracy was analyzed by Hirata-Fujita and Maior-Swenson equations.
