Abstract
Methanol과 ethanol을 포함하는 2성분계 공비 혼합물에 대하여 400 mmHg∼800 mmHg의 압력범위에서 공비 온도와 조성을 측정하였고, UNIFAC식을 이용하여 계산한 값과 비교하였다.
또한, 공비 온도는 압력과 Antoine식과 같은 관계식을 가지며, 공비 조성은 각 압력에서의 순성분 비점과 ln（x1/x2）=A'ln((T2-Taz)/(T1-Taz))+B'의 관계를 가짐을 알 수 있었다. 그리고 두 식에 대한 상수 값을 각 계에 대하여 결정하였다.

For 9 binary azeotropes containing methanol and ethanol, the azeotropic temperatures and compositions were measured within the pressure range of 400 mmHg-800 mmHg. The measured values were compared with those calculated by the UNIFAC equation.
Also, we could get two types of empirical formula of azeotropic data with pressures and boiling points. The one is similar to Antoine equation, and the other is ln（x1/x2）=A'ln((T2-Taz)/(T1-Taz))+B', wherein all the optimum values of constants in both equations were provided for the systems illustrated.
