Abstract

The flash point is one of the most important combustible properties used to determine the potential for fire and explosion hazards of industrial material. An accurate knowledge of the flash point is important in developing appropriate preventive and control measures in industrial fire protection. The flash points for the n-butanol+n-propionic acid and n-propanol+n-propionic acid systems were measured by using Tag open-cup apparatus(ASTM D 1310-86). The experimental data were compared with the values calculated by the laws of Raoult and van Laar equation. The calculated values based on the van Laar equation were found to be better than those based on the Raoult's law.

인화점은 가연성 물질의 화재 및 폭발의 잠재위험성을 결정하는데 가장 중요한 연소 특성치 가운데 하나이다. 인화점의 정확한 지식은 산업 화재의 방호 평가 및 적절한 예방에 중요하다. 본 연구에서 n-butanol+n-propionic acid계와, n-propanol+n-propionic계의 개방계 인화점을 Tag식 개방계 장치(ASTM D 1310-86)를 이용하여 측정하였다. 실험값은 라울의 법칙과 van Laar식에 의해 계산된 값과 비교하였다. 그 결과, van Laar식에 의한 예측값이 라울의 법칙에 의한 예측값 보다 실험값에 더욱 근사함을 확인하였다.
