摘要:	閃火點為描述液體火災爆炸的重要資訊。部分互溶混合溶液主要使用在非勻相蒸餾製程和液液萃取程序中。本研究目的在建立多成份部份互溶有機水溶液之閃火點預測模式。使用水 + 乙醇 + 正丁醇、水 + 正丁醇 + 2-丁醇以及水 + 乙醇 + 2-丁醇之三種有機水溶液實驗數據來驗證模式的預測能力。模擬過程利用VLLE參數來推估Tie Line及其閃火點，VLE參數被使用來推估互溶區的閃火點。此閃火點預測模式經實驗數據驗證，在模擬過程中不但能有效的估計互溶區及部份互溶區的範圍，並且能預測每條Tie Line上的閃火點為一定值。 Flash point is a variable used in characterizing fire and explosion hazard of liquids. The partially miscible mixtures are used in heterogeneous distillation process and liquid-liquid extraction process. The purpose of this study is to build a mathematical model to predict the flash point of the ternary partially miscible mixtures of aqueous-organic system. The proposed model was validated by use of water +ethanol + 1-butanol, water + ethanol + 2-butanol and water + 1-butanol + 2-butanol mixtures. The VLLE parameters were used to estimate the span of the tie lines and their flash point, and the VLE parameters were used to estimate the flash point in mutual solubility region. The flash point prediction model was verified by the experimental data to be able to estimate the range of the miscible and partially miscible phase during the simulation, as well as the constant flash point on each tie line.
