Abstract

Flash point is the one of the important properties for the safe handling of inflammable liquid solution. In this paper, flash points of binary liquid solutions, water+1-propanol and water+2-propanol, were been measured by using Seta flash closed cup aparatus. Flash point was estimated using regression analysis method. Flash points were also estimated by the method based on Raoul's law and the method optimizing the binary parameters of van Laar equation. Experimental results were compared with the calculated results. The regression analysis method is able to estimate the flash point fairly well for water+1-propanol and water+2-propanol mixture.

인화점은 가연성 액체 용액을 안전하게 취급하기 위한 중요한 성질 중 하나이다. 본 논문에서는 Seta flash 밀폐식 장치를 이용하여 이성분계 용액인 water+1-propanol과 water+2-propanol계의 인화점을 측정하였다. 회귀 분석법을 이용하여 인화점을 계산하였다. 또한 라울의 법칙을 이용하여 인화점을 계산하였고, van Laar 식의 이성분계 파라미터를 최적화시키는 방법을 통해 인화점을 예측하였다. 각 인화점 계산 결과와 측정 결과를 비교하였다. 그 결과, 회귀 분석법에 의한 인화점 계산치가 가장 측정치를 잘 모사하였다.
