요약

최소자연발화온도는 가연성액체의 안전한 취급을 위해서 중요한 지표가 된다. 본 연구에서는 ASTM E659 장치를 이용하여 가연성 혼합물인 n-Butanol+sec-Butanol 계의 최소자연발화온도와 발화지연시간을 측정하였다. 2성분계를 구성하는 순수물질인 n-Butanol과 sec-Butanol의 최소자연발화온도는 각 각 $340^{circ}C$, $447^{circ}C$로 측정되었다. 그리고 측정된 n-Butanol+sec-Butanol 계의 최소자연발화온도는 제시된 식에 의한 예측값과 적은 평균절대오차에서 일치하였다.

Abstract

The autoignition temperature (AIT) is important index for the safe handling of flammable liquids which constitute the solvent mixtures. This study measured the AITs and ignition delay time for n-Butanol+sec-Butanol system by using ASTM E659 apparatus. The AITs of n-Butanol and sec-Butanol which constituted binary system were $340^{circ}C$ and $447^{circ}C$, respectively. The experimental AITs of n-Butanol+sec-Butanol system were a good agreement with the calculated AITs by the proposed equations with a few A.A.D. (average absolute deviation).
