Abstract

The flash point is one of the most important properties for characterizing the fire and explosion hazard of liquid solutions. In this study, a Tag open-cup apparatus was used to measure the flash points of two flammable binary mixtures, n-decane + n-octanol and acetic acid + n-butanol. The flash point temperature was estimated using the UNIFAC (Universal Functional Activity Coefficient) group contribution model and optimization method. The experimentally derived flash point was also compared with the predicted flash point. The two methods can estimate the flash point fairly well for the n-decane + n-octanol and acetic acid + n-butanol systems.

인화점은 액체 용액의 폭발과 화재의 위험성을 특징짓는 가장 중요한 성질 중 하나이다. 본 연구에서는 두개의 가연성 이성분계 혼합물인 n-decane + n-octanol계 및 acetic acid + n-butanol계의 인화점을 Tag 개방식 장치를 활용하여 측정하였다. 인화점은 그룹기여모델인 UNIFAC 식과, 최적화기법에 의해 계산되었다. 그리고 측정값과 비교하였다. 두 방법 모두 측정값을 잘 모사하였다.
