Abstract

For the safe handling of isoamyl alcohol being used in various ways in the chemical industry, the flash point and the autoignition temperature(AIT) of isoamyl alcohol was experimented. And, the lower explosion limit of isoamyl alcohol was calculated by using the lower flash point obtained in the experiment. The flash points of isoamyl alcohol by using the Setaflash and Pensky-Martens closed-cup testers measured $31^{\circ}C$ and $33^{\circ}C$, respectively. The flash points of isoamyl alcohol by using the Tag and Cleveland open cup testers are measured $43^{\circ}C$and $45^{\circ}C$. The AIT of isoamyl alcohol by ASTM 659E tester was measured as $419^{\circ}C$. The lower explosion limit by the measured flash point $31^{\circ}C$ was calculated as 0.87 vol%. It was possible to predict lower explosion limit by using the experimental flash point or flash point in the literature.

화학산업에서 다양하게 사용되고 있는 이소아밀알코올의 안전한 취급을 위해서 인화점과 최소자연발화온도를 측정하였다. 폭발하한계는 실험에서 얻어진 하부인화점을 이용하여 계산하였다, 이소아밀알코올의 Setaflash 밀폐식은 $42^{\circ}C$, Pensky-Martens 밀폐식에서는 $43^{\circ}C$ 그리고 Tag 개방식에서는 $46^{\circ}C$, Cleveland 개방식에서는 $54^{\circ}C$로 측정되었다. ASTM E659 장치에 의한 이소아밀알코올의 최소자연발화온도는 $327^{\circ}C$로 측정되었다. 측정된 하부인화점 $42^{\circ}C$에 의한 폭발하한계는 1.41 vol%로 계산되었다. 폭발한계는 측정된 인화점이나 문헌에 제시된 인화점을 이용하여 예측 가능함을 알 수 있었다.
