Abstract

To propose a model equation, an acetic acid and n-heptane binary vapor liquid equilibrium system were investigated at 298.15K and 318.15K. Pressure was theoretically estimated using an association model based on the chemical theory, in conjunction with Margules, Wilson, NRTL models. Results were compared with those of calculated values without considering association. The theoretically calculated results of association model equations show a good agreement with the experimentally observed values.

초산의 회합성을 설명할 수 있는 모델식을 비교 제안하기 위해 298.15K와 318.15K의 실험치 자료를 화학적 이론이 고려된 전개식과 일반적인 기액 평형식에 Margules, Wilson, NRTL식을 각각 적용하여 계산한 값들을 서로 비교하였다. 회합성이 고려된 모델식을 적용하여 계산한 값이 실험치와 잘 일치하였다.
