Abstract

The autoignition temperature (AIT) of a material is the lowest temperature at which the material will spontaneously ignite. The AIT is important index for the safe handling of flammable liquids which constitute the solvent mixtures. This study measured the AITs of n-decane+ethylbenzene system by using ASTM E659 apparatus. The AITs of n-decane and ethylbenzene which constituted binary system were $210^{\circ}C$ and $430^{\circ}C$, respectively. The experimental AITs of n-decane+ethylbenzene mixture were a good agreement with the calculated AITs by the proposed equations with about $11^{\circ}C$ A.A.D.(average absolute deviation).

최소자연발화온도는 가연성물질이 주위의 열에 의해 스스로 발화하는 최저온도이다. 최소자연발화온도는 유기혼합물중 가연성 액체혼합물의 안전한 취급을 위해서 중요한 지표가 된다. 본 연구에서는 ASTM E659 장치를 이용하여 가연성 혼합물인 노말데칸과 에틸벤젠 계의 최소자연발화온도를 측정하였다. 이성분계를 구성하는 노말데칸과 에틸벤젠의 최소자연발화온도는 각 각 $210^{\circ}C$, $430^{\circ}C$로 측정되었다. 그리고 측정된 노말데칸과 에틸벤젠 혼합물의 최소자연발화온도는 제시된 식에 의한 예측값과 약 $11^{\circ}C$평균절대오차에서 일치하였다.
