요약

사이클로헥사논의 안전한 취급을 위해서 $25^{circ}C$에서 폭발한계를 고찰하였고, 실험장치를 이용하여 하부 인화점과 발화지연시간에 의한 발화온도를 측정하였다. 공정의 안전을 위해서 사이클로헥사논의 폭발하한계는 1.1 Vol.%($100^{circ}C$), 상한계는 9.4 Vol.%를 추천하였고, 하부인화점은 밀폐계에서 $42{sim}43^{circ}C$와 개방식에서 $49{sim}51^{circ}C$로 측정되었다. ASTM E659-78 장치를 사용하여 자연발화온도와 발화지연시간을 측정하였고, 여기서 측정된 최소자연발화온도는 $415^{circ}C$였다.

Abstract

For the safe handling of cyclohexanone, the explosion limits at $25^{circ}C$ were investigated. The lower flash points and AITs (auto-ignition temperatures) by ignition time delay for cyclohexanone were experimented. By using the literatures data, the lower and upper explosion limits of cyclohexanone recommended 1.1 Vol.% ($100^{circ}C$) and 9.4 Vol.%, respectively. The lower flash points of cyclohexanone were experimented $42{sim}43^{circ}C$ by using closed-cup tester and $49{sim}51^{circ}C$ by using open cup tester. This study measured relationship between the AITs and the ignition delay times by using ASTM E659-78 apparatus for cyclohexanone and the experimental AIT of cyclohexanone was $415^{circ}C$.
