Abstract
The lower flash points for the n-pentanol+n-propionic acid and n-pentanol+n-butyric acid systems, in air at atmospheric pressure, were measured by using Pensky-Martens closed cup apparatus. The experimental data were compared with the values calculated by the Raoult's law and optimization method. The calculated values based on the optimization method were found to be better than those based on the Raoult's law.
가연성 이성분계 혼합물인 n-pentanol+n-propicnic acid 및 n-pentanol+n-butyric acid 계의 하년 인화점이 상압 조건 하에서 Pensky-Martens 밀폐식 장치에 의해 측성되었다. 실험값을 라울의 법칙과 최적화 기법을 활용한 예측간과 비교하였다. A.A.D.(average absolute deviation)에서 알 수 있듯이, 최적화 기법을 활용한 예측값이 Raoult의 법칙에 의한 예측값 보다 실험값에 더욱 근사하였다.
