Ethy lbenzene+n -pentanol 계의 인화점 측정과 예측

국문 초록 (Abstract)

본 연구에서는 최소인화점 현상을 보이는 Ethylbenzene+n-pentanol계의 인화점을 Tag 개방장치 (ASTMD 1310-86 )을 이용하여 측정하였다. 실험값은 Raoult의 법칙，van Laar 모델식과 Wilson 모델식에 의해 계산된 값들과 비교되었다. 그결과, van Laar 모델식과 WIison 모델식에 의한 예측값이 Raoult의 법칙에 의한 예측값보다 실험값에 더욱 근접하였다. 이는 Ethylbenzene+n-pentanol 계와 같은 비이상 용액의 활동도 계수값을 van Laar 모델식과 WIison 모델식이 Raoult의 법칙보다 정확하게 계산하기 때문이다.

다국어 초록 (Multilingual Abstract)

In this study, the flash points for the Ethylbenzene+n-pentanol system which exhibit MFPB, were measured by Tag open-cup apparatus. The experimental data were compared with values calculated by Raoult’s Law, the van Laar equation and Wilson equation. The calculated values based on the van Laar and Wilson equations were found to be better than those based on the Raoult’s Law. It was conconcluded that the van Laar and Wilson equations were more effective than the Raoult’s than the Raoult’s Law at describing the activity coefficients for non-ideal solution such as the Ethylbenzene+n-pentanol system.
