요약

노말노난올의 안전한 취급을 위해, 폭발한계는 문헌을 통해 고찰하였고, 인화점과 발화지연시간에 의한 발화온도를 측정하였다. 그 결과, 노말노난올의 폭발하한계는 0.80 Vol.%, 상한계는 6.1 Vol.%를 추천하였고, 하부인화점은 밀폐계에서 $94{sim}97^{circ}C$와 개방식에서 $103{sim}104^{circ}C$로 측정되었다. ASTM E659-78 장치를 사용하여 자연발화온도와 발화지연시간을 측정하였고, 노말노난올의 최소자연발화온도는 $270^{circ}C$로 측정되었다.

Abstract

For the safe handling of n-nonanol, this study was investigated the explosion limits of n-nonanol in the reference data. The flash points and AITs (autoignition temperatures) by ignition delay time were experimented. As a results, the lower and upper explosion limits of n-nonanol recommended 0.8 Vol.% and 6.1 Vol.%, respectively. The lower flash points of n-nonanol by using closed-cup tester were experimented $94{sim}97^{circ}C$. The lower flash points of n-nonanol by using open cup tester were experimented $103{sim}104^{circ}C$. This study measured relationship between the AITs and the ignition delay times by using ASTM E659-78 apparatus for n-nonanol. The experimental AIT of n-nonanol was $270^{circ}C$.
