Abstract

인화점은 공기와 섞인 가연성 증기의 농도가 발화하기에 충분할 때의 최저 온도로, 가연성 액체 용액의 화재 및 폭발 위험성을 분석하는데 사용되는 주된 물리적 특성치이다. 단일 성분의 인화점 정보는 여러 문헌에서 얻을 수 있으나, 가연성 이성분계 혼합물의 인화점은 충분히 제공되어 있지 않다. 본 연구의 목적은 이성분계 가연성 액체 혼합물인 아세트산-포름산계의 인화점을 측정하고, 산출하는 것이다. 인화점 측정은 Cleveland 개방식 장치를 사용하였고, 실험값은 van Laar 식과 Wilson 식을 활용한 최적화 기법에 의해 산출된 값과 비교하였다. 그리고 라울의 법칙에 의해 산출된 값과 비교되었다. 그 결과, 최적화 기법에 의한 산출값이 Rauolt의 법칙에 의한 산출값보다 실험값에 보다 근접하였다. The flash point is the lowest temperature at which there is enough concentration of flammable vapor to form an ignitable mixture with air. The flash point is a major physical property used to analyse the fire and explosion hazards of a flammable liquid solution. The flash point data for pure components are easily available in several literature. But the flash points of the flammable binary solutions appear to be scarce in the literature. The objective of this study is to measure and estimate the flash point of acetic acid-formic acid system. Cleveland open cup tester was used to measure the flash point. The experimental data were compared with the values estimated by the Raoult's law and the optimization methods based on van Laar and Wilson equations. As a result, the estmated values by optimization methods were found to be better than those based on the Raoult's law.
