Abstract

The usage of the correct combustion characteristic of the treated substance for the safety of the process is critical. For the safe handling of cumene being used in various ways in the chemical industry, the flash point and the autoignition temperature (AIT) of cumene was experimented. And, the lower explosion limit of cumene was calculated by using the lower flash point obtained in the experiment. The flash points of cumene by using the Setaflash and Pensky-Martens closed-cup testers measured $31^{\circ}C$ and $33^{\circ}C$, respectively. The flash points of cumene by using the Tag and Cleveland open cup testers are measured $43^{\circ}C$ and $45^{\circ}C$. The AIT of cumene 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.

공정의 안전을 위해서 취급물질의 정확한 연소특성치의 사용은 매우 중요하다. 화학산업에서 다양하게 사용되고 있는 큐멘의 안전한 취급을 위해서 인화점과 최소자연발화온도를 측정하였다. 폭발하한계는 실험에서 얻어진 하부인화점을 이용하여 계산하였다. 큐멘의 Setaflash 밀폐식은 $31^{\circ}C$, Pensky-Martens 밀폐식에서는 $33^{\circ}C$ 그리고 Tag 개방식에서는 $43^{\circ}C$, Cleveland 개방식에서는 $45^{\circ}C$로 측정되었다. ASTM E659 장치에 의한 큐멘의 최소자연발화온도는 $419^{\circ}C$로 측정되었다. 측정된 하부인화점 $31^{\circ}C$에 의한 폭발하한계는 0.87 vol%로 계산되었다. 폭발한계는 측정된 인화점이나 문헌에 제시된 인화점을 이용하여 예측가능함을 알 수 있었다.
