Abstract

For the safe handling of cyclohexane, the explosion limit at $25^{\circ}C$ and the temperature dependence of the explosion limits were investigated. Flash point and AIT(autoignition temperature) for cyclohexane were experimented. By using the literatures data, the lower and upper explosion limits of cyclohexane recommended 1.0 Vol% and 9.0 Vol%, respectively. Moreover lower flash points of cyclohexane recommended $-20^{\circ}C$. It was measured relationship between the AITs and the ignition delay times by using ASTM E659-78 apparatus for cyclohexane, and the experimental AIT was $255^{\circ}C$. The new equations for predicting the temperature dependence of the explosion limits of cyclohexane is proposed. The values calculated by the proposed equations were a good agreement with the literature data.

사이클로헥산의 안전한 취급을 위해서 $25^{\circ}C$에서 폭발한계와 폭발한계 온도의존성 그리고 하부인화점을 고찰하였다. 또한 발화지연시간에 의한 발화온도를 측정하였다. 공정의 안전을 위해서 노말헵탄의 폭발하한계는 1.0 Vol%, 상한계는 9.0 Vol%를 추천하였고, 하부인화점은 $-20^{\circ}C$를 추천하였다. ASTM E659-78 장치를 사용하여 발화온도와 발화지연시간을 측정하였고, 여기서 측정된 최소자연발화온도는 $255^{\circ}C$였다. 그리고 노말헵탄의 새로운 폭발한계 온도의존식을 제시하였으며, 제시된 식은 문헌값과 일치하였다.
