초록

인화점은 화재 및 액체의 폭발 위험의 가능성을 결정하는 데 사용되는 가장 중요한 물리적 특성이고, 산업공정에서 안정성 평가시 중요한 연소특성 가운데 하나이다. 따라서 본 연구는 4류 위험물 중 알코올계 혼합물인 {methanol + 1-butanol}, {ethanol + 1-butanol} 그리고 {2-propanol + 1-butanol} 이성분계 101.3 kPa에서 최소인화점을 SETA closed cup flash point tester를 이용하여 측정하였다. 각 이성분계에 대하여 Wilson, NRTL 및 UNIQUAC 파라미터를 이용하여 혼합물에 대한 인화점 예측하고 실험 결과와 비교하였다. 비교결과 모든 예측값과 실험값은 유사한 값을 보였고 편차가 1.14 K 이내의 결과를 보였다.

Flash point is one of the most important variables used to characterize fire and explosion hazard of liquids. The lower flash point data were measured for the binary systems {methanol + 1-butanol}, {ethanol + 1-butanol} and {2-propanol + 1-butanol} at 101.3 kPa. Experiments were performed according to the standard test method (ASTM D 3278) using a SETA closed cup flash point tester. The measured flash points were compared with the predicted values calculated using the following activity coefficient models: Wilson, Non-Random Two Liquid (NRTL), and UNIversal QUAsiChemical (UNIQUAC). The measured FP data agreed well with the predicted values of Raoult's law, Wilson, NRTL and UNIQUAC models. The average absolute deviation between the predicted and measured lower FP was less than 1.14 K.
