Abstract

For the safe handling of isopropyl alcohol, the explosion limits were investigated. The lower flash points, upper flash points, fire point, and AITs(autoignition temperatures) by ignition time delay for isopropyl alcohol were experimented. By using literature data, the lower and upper explosion limits of isopropyl alcohol were recommended as 2.0 and 12.0 vol%, respectively. The lower flash points of isopropyl alcohol were experimented $12{\sim}14^{\circ}C$ by using closed-cup tester and $18{\sim}19^{\circ}C$ by using open cup tester. And the upper flash points of isopropyl alcohol was experimented $38^{\circ}C$ by using Setaflash closed-cup tester. This study measured relationship between the AITs and the ignition delay times by using ASTM E659 apparatus was $463^{\circ}C$.

이소프로필 알코올의 안전한 취급을 위해 $25^{\circ}C$에서 폭발한계를 고찰하였고, 실험장치를 이용하여 하부인화점, 상부인화점, 연소점 그리고 발화지연시간에 의한 발화온도를 측정하였다. 그 결과, 공정의 안전을 위한 이소프로필 알코올의 폭발 하한계는 2.0 vol%이고, 상한계는 12.0 vol%로 문헌을 통해 판단되었다. 하부인화점은 밀폐계에서 $12{\sim}14^{\circ}C$와 개방식에서 $18{\sim}19^{\circ}C$이었고, 상부인화점은 $38^{\circ}C$로 측정되었다. ASTM E659 장치를 사용하여 측정된 최소자연발화온도는 $463^{\circ}C$이었다.
