Abstract

The combustion properties for the prevention of the fire and explosion in the work place are flash point, explosion limit, autoignition temperature (AIT) etc.. The using of the corrective combustion properties of the MSDS (Material Safety Data Sheet) of the handling substance for the chemical process safety is very important. For the safe handling of benzyl alcohol which is widely used in the chemical industry, the flash point and the AIT were measured. And, the lower explosion limit (LEL) of benzyl alcohol was calculated by using the lower flash point which obtained in the experiment. The flash points of benzyl alcohol by using the Setaflash and Pensky-Martens closed-cup testers measured $90^{\circ}C$ and $93^{\circ}C$, respectively. The flash points of benzyl alcohol by using the Tag and Cleveland open cup testers are measured $97^{\circ}C$ and $100^{\circ}C$. The experimental AIT of benzyl alcohol by ASTM 659E tester was measured as $408^{\circ}C$. The LEL of benzyl alcohol measured by Setaflash closed-cup apparatus was calculated as 1.17 vol% at $90^{\circ}C$. In this study, it was to possible predict the LEL by using the lower flash point of benzyl alcohol which measured by Setaflash closed-cup tester.

사업장에서 화재 및 폭발을 예방하기 위해서는 연소특성치로 인화점, 폭발한계, 최소자연발화온도 등을 들 수 있다. 화학공정의 안전을 위해서 취급 물질의 정확한 물질보건안전자료(MSDS)의 연소특성치 사용은 매우 중요하다. 화학산업에서 다양하게 사용되고 있는 벤질알코올의 안전한 취급을 위해서 인화점과 최소자연발화온도를 측정하였다. 벤질알코올의 폭발하한계는 실험에서 얻어진 하부인화점을 이용하여 계산하였다. 벤질알코올의 Setaflash 밀폐식은 $90^{\circ}C$, Pensky-Martens 밀폐식에서는 $93^{\circ}C$ 그리고 Tag 개방식에서는 $97^{\circ}C$, Cleveland 개방식에서는 $100^{\circ}C$로 측정되었다. ASTM E659 장치에 의한 측정된 벤질알코올의 최소자연발화온도는 $408^{\circ}C$로 측정되었다. Setaflash 밀폐식에 의해 측정된 벤질알코올의 하부인화점 $90^{\circ}C$의 폭발하한계는 1.17 vol%로 계산되었다. 본 연구에서는 Setaflash 밀폐식에 의해 측정된 벤질알코올의 하부인화점을 이용하여 폭발하한계의 예측이 가능하였다.
