Abstract

The lowest values of the AITs(Autoignition temperatures) in the literature were normally used fire and explosion protection. In this study, the AITs of n-Propanol+n-Octane system were measured from ignition delay time(time lag) by using ASTM E659 apparatus. The AITs of n-Propanol and n-Octane which constituted binary systems were $435^{\circ}C$ and $218^{\circ}C$, respectively. The experimental ignition delay time of n-Propanol+n-Octane system were a good agreement with the calculated ignition delay time by the proposed equations with a few A.A.D.(average absolute deviation).

화재 및 폭발 방호를 위해서 문헌에서의 최소자연발화온도 값을 사용하는 것이 일반적이다. 본 연구에서, n-Propanol+n-Octane 계의 최소자연발화온도는 ASTM E659 장치를 이용하여 발화지연시간으로부터 측정하였다. 2성분계를 구성하는 n-Propanol과 n-Octane의 측정된 최소자연발화온도는 각 각 $435^{\circ}C$와 $218^{\circ}C$ 였다. 그리고 두 개의 2성분계에서 측정된 발화지연시간은 제시된 식에 의한 예측된 발화지연시간과 적은 평균절대오차에서 일치하였다.
