노말노난올의 연소특성치 측정에 의한 위험성 평가

Risk Assessment by Means of Measurement of Combustible Characteristics for n-Nonanol

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 <TEX>$94{\sim}97^{\circ}C$</TEX>와 개방식에서 <TEX>$103{\sim}104^{\circ}C$</TEX>로 측정되었다. ASTM E659-78 장치를 사용하여 자연발화온도와 발화지연시간을 측정하였고, 노말노난올의 최소자연발화온도는 <TEX>$270^{\circ}C$</TEX>로 측정되었다.

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 <TEX>$94{\sim}97^{\circ}C$</TEX>. The lower flash points of n-nonanol by using open cup tester were experimented <TEX>$103{\sim}104^{\circ}C$</TEX>. 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 <TEX>$270^{\circ}C$</TEX>.
