초록

가연성 액체 혼합물의 화재 위험성을 특징짓는 주된 물리적 성질은 인화점이다. 본 연구는 이성분계 가연성 혼합물의 인화점을 측정하고 예측하고자 한다. Seta flash 밀폐식 장치를 이용하여 n-propanol+propionic acid 계의 인화점을 측정하였다. van Laar 식과 NRTL 식을 이용한 최적화 기법을 통해 인화점을 예측하였다. 이 계산치와 라울의 법칙에 의한 계산치를 비교하였다. 그 결과, 최적화 기법에 의한 계산치가 라울의 법칙에 의한 계산치 보다 측정값에 보다 근사하였다.

The flash point is the major physical property used to characterize the fire hazard of flammable liquid solutions. In the present study, the main focus is on measuring and estimating the flash points for binary flammable mixture. The flash points for n-propanol+propionic acid were measured by Seta flash closed cup apparatus. The experimental data were correlated with the van Laar and NRTL equations through the optimization method. The results estimated by these correlations were compared with the values calculated by the method based on Raoult's law. The optimization method were found to be better than the method based on the Raoult's law.
