Abstract
인화점은 가연성물질의 화재 및 폭발의 잠재위험성을 결정하는데 가장 중요한 기초적인 특성치 가운데 하나이다. 인화점의 정확한 지식은 산업 화재의 방호 평가 및 적절한 예방에 중요하다. n-Propanol+n-Propionic Acid계와, n-Butanol+n-Propionic Acid계의 하부 인화점은 Pensky-Martens 밀폐식 장치를 이용하여 측정하였다. 실험 자료는 라울의 법칙과 van Laar식에 의해 계산된 값과 비교 하였다. n-Propanol+n-Propionic Acid계에 대한 하부 인화점의 경우에는 van Laar식에 의해 예측된 값보다 라울의 법칙 의해 예측된 값이 더 일치하였다. n-Butanol+n-Propionic Acid계에 대한 하부 인화점의 경우에는 라울의 법칙 의해 예측된 값보다 van Laar식에 의해 예측된 값이 더 일치하였다.
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 lower flash points of the n-Propanol+n-Propionic Acid and n-Butanol+n-Propionic Acid systems were measured by using Pensky-Martens closed cup tester. The experimental data were compared with the values calculated by the laws of Raoult and van Laar equation. In case of the lower flash point of the n-Propanol+ n-Propionic Acid system, the calculated values based on the Raoult’s law were found to be better than those based on the van Laar equation. In case of the lower flash point of the n-Butanol+n-Propionic Acid system, the calculated values based on the van Laar equation were found to be better than those based on the Raoult’s law.
