Binary mixtures exhibiting maximum flash-point behavior.

This study has demonstrated the existence of maximum flash-point solutions, where the maximum flash-point value is larger than those of the individual components. The behavior of such a solution has potential application in hazard reduction. The sufficient condition for a binary mixture to form such a maximum flash-point solution, and the equations to determine its composition and maximum flash point are proposed here, as these may be important in terms of hazard reduction. The sufficient condition and associated equations were verified by comparison with the experimental data. Our results reveal that this derived condition is satisfactory to establish that a liquid mixture is a maximum flash-point solution. The proposed equations may be successfully applied to estimate the composition and maximum flash-point value of such a mixture.
