Abstract

The flash points for the systems, o-xylene+n-pentanol and m-xylene+n-hexanol, were measured by using Tag open-cup tester(ASTM D1310-86). The experimental data were compared with the values calculated by the Raoult's law and the optimization method using van Laar and Wilson equations. The calculated values based on the optimization method were found to be better than those based on the Raoult's law. The predictive curve of the flash point prediction model based on the van Laar equation described the experimentally-derived data more effectively than was the case when the prediction model was based upon the Wilson equation.

본 연구에서는 o-xylene+n-pentanol 및 m-xylene+n-hexanol 계의 인화점을 Tag 개방식 장치(ASTM D1310-86)를 이용하여 측정하였다. 실험값은 Raoult의 법칙, van Laar 및 Wilson 식을 이용한 계산된 값들과 비교하였다. 그 결과, 최적화법에 의한 예측값이 Rauolt의 법칙에 의한 계산 보다 실험값에 더욱 근접하였다. 또한, van Laar 식을 사용한 최적화법이 Wilson 식에 의한 최적화법 보다 실험값에 대한 모사성이 우수하였다.
