Abstract

The flash point is one of the most important physical properties to charaterize fire and explosion hazard of liquid solutions. The maximum flash point of liquid mixture is larger than those of the individual components. In this study, the flash points of 2-pentanol+acetic acid system were measured by Seta flash closed cup tester. This system exhibited the maximum flash point behavior. The flash points were estimated by the Raoult's law and the optimization methods using the van Laar and Wilson equations. The calculated values by optimization methods were found to be better than those based on the Raoult's law.

인화점은 액체 용액의 폭발과 화재의 위험성을 특징짓는 가장 중요한 물성치 중 하나이다. 액체 혼합물의 최대인화점은 용액을 구성하는 개별 성분들의 인화점보다 높은 것을 의미한다. 본 연구에서는 2-pentanol+acetic acid 계의 인화점을 Seta flash 밀폐식 장치를 통해 측정하였다. 이 계는 최대인화점 현상을 나타내었다. 또한 인화점은 Raoult의 법칙을 이용하여 예측하였고, van Laar 식과 Wilson 식을 활용한 최적화 기법에 의해서도 예측하였다. 최적화 기법에 의한 예측 방법이 Rauolt의 법칙에 의한 예측 방법 보다 측정치를 잘 모사하였다.
