Abstract | The flash point is one of the most important properties for characterizing the fire and explosion hazard of liquid solutions. In this study, the flash points of two flammable binary mixtures, n-pentanol + n-propanol and n-pentanol + n-heptanol systems were measured using a Seta flash closed cup tester. The flash point was estimated using the methods based on Raoult's law and multiple regression analysis. The measured flash points were also compared with the predicted flash points. The absolute average errors (AAE) of the results calculated by Raout's law were $1.3^{\circ}C$ and $1.3^{\circ}C$ for the n-pentanol + n-propanol and n-pentanol + n-heptanol mixtures, respectively. The absolute average errors of the results calculated by multiple regression analysis were $0.4^{\circ}C$ and $0.3^{\circ}C$ for the n-pentanol + n-propanol and n-pentanol + n-heptanol mixtures, respectively. According to the AAE, the calculated values based on multiple regression analysis were better than those based on Raoult's law. 인화점은 가연성 액체 용액의 폭발과 화재의 위험성을 결정하는 가장 중요한 성질 중 하나이다. 본 연구에서는 2개의 가연성 이성분계 혼합물인 n-pentanol + n-propanol계 및 n-pentanol + n-heptanol계의 인화점을 Seta flash 밀폐식 장치를 사용하여 측정하였다. 인화점은 라울의 법칙을 이용한 방법과 다중회귀분석법에 의해 계산되었다. 그리고 그 결과를 측정값과 비교하였다. 라울의 법칙에 의해 계산된 결과의 절대평균오차는 n-pentanol + n-propanol계인 경우 $1.3^{\circ}C$이며 npentanol + n-heptanol계인 경우 $1.3^{\circ}C$이었다. 다중회귀분석법에 의해 계산된 결과의 절대평균오차는 n-pentanol + npropanol계인 경우 $0.4^{\circ}C$이며 n-pentanol + n-heptanol계인 경우 $0.3^{\circ}C$이었다. 절대평균오차에서 알 수 있듯이 다중회귀 분석법에 의한 계산값이 라울의 법칙에 의한 계산값에 비해 측정값을 잘 모사하였다. |
