摘要:	不論是易燃液體的操作、運輸或儲存，閃火點都是描述物質火災爆炸危害最重要的指標之一，閃火點會因混合溶液種類的不同而有不一樣的行為變化，先前的研究證明雙成分最高閃火點溶液的閃火點會高於純物質的閃火點，可應用於火災爆炸的危害削減，然而現實中混合溶液的成分數往往多於雙成分，故三成分易燃液體的最高閃火點行為值得進一步去探討。本研究利用具有最高閃火點行為的雙成分溶液，加入第三成分來探討閃火點行為的變化，實驗共選擇酚(phenol)＋環己醇(cyclohexanol)＋環己酮(cyclohexanone)、酚(phenol)＋苯乙酮(acetophenone)＋丙醇(1-propanol)及酚(phenol)＋環己醇(cyclohexanol)＋苯甲醇(benzyl alcohol)三組三成分混合溶液，利用德國Walter Herzog GmbH公司所製造的HFP 362-Tag塔式閃火點測試儀及HFP 360-Pensky Martens潘馬式閃火點測試儀進行閃火點實驗，標準測試方法遵守ASTM D56及ASTM D93B閉杯測試法，實驗結果並與各活性係數方程式模擬數據進行比對。研究結果分析了三種不同特性的三成分混合溶液，呈現出三種不同的閃火點行為變化，對於存在極端閃火點行為的三成分溶液，提供了三個可能的閃火點行為表現，為往後三成分溶液閃火點行為提供更多辨識的類型，擴大多成分負偏差溶液閃火點的研究以及幫助易燃液體危害的削減。 Flash point is the major and important physical property to charactize the fire and explosion hazards of substances in the operatation, transportation and storage of flammable (or combustible) liquid. Different mixtures of flammable solvents appear different flash point behaviors. The study of binary mixtures exhibiting maximum flash point behavior had verified flash point of the mixture may be larger than those of the individual components and it decrease the risk of fire and explosion. However, the number of mixture solvents often larger than two components. Therefore the ternary flammable solvents maximum flash point behavior deserved to investigate. In this study, the flash point of ternary solutions were tested by the flash point tester(Walter Herzog GmbH HFP 362-Tag and HFP 360-Pensky Martens) .Three ternary solutions：phenol＋cyclohexanol＋cyclohexanone, phenol＋acetophenone＋1-propanol and phenol＋cyclohexanol＋benzyl alcohol were used to investigate maximum flash point behavior of ternary solutions. The experimental results were compared with the data of flash point prediction model. The change of flash point behavior at binary maximum flash point mixtures addition of a third component observed in this study. The results displayed three different ternary flash point behaviors, and provided more possible behaviors to classification. The study of negative deviation of multi-component had promoted and reduced the risk of flammable solvents.
