Abstract

For the binary system of methanol/3-methyl-1-butanol mixture vapor-liquid equilibrium data were measured isothermally at 50, 55, 60, 65, and $70^{\circ}C$. An empirical relation to predict vapor-liquid equilibrium data was obtained from the above measured data. The predicted values compared with the measured ones were in a good agreement, within accuracy ${\pm}0.0007$. The excess molar volume, measured for the binary system of methanol/3-methyl-1-butanol mixture, was positive $V^Eover$ the entire composition range. The maximum values were shown to be about $0.096cm^3/mol$ at x= 0.683.

이성분 methanol/3-methyl-1-butanol계에 대하여 정온하 즉 50, 55 60, 65 및 $70^{\circ}C$에서의 기-액평형치를 측정하고, 그 측정치를 이용하여 기-액평형치를 추산하는 추산식을 이끌어 내었다. 측정치와 추산치를 비교 검토한 결과 기상조성의 몰분율은 ${\pm}0.0007$의 오차범위 내에서 잘 일치하고, methanol/3-methyl-1-butanol계에 대한 과잉 몰부피를 측정한 결과 전체 조성범위에서 양의 편차를 나타내며 최대치는 x= 0.683에서 $0.096cm^3/mol$로 나타났다.
