Mixtures exhibiting maximum flash point behavior (MaxFPB) have the potential to reduce the fire and explosion hazard of liquids, such as waste solvent and liquid fuel. Commercial mixtures generally contain multiple components. However, existing research on MaxFPB is limited mainly to binary mixtures. Accordingly, the present study extends the literature by examining the MaxFPB of three ternary mixtures, namely phenol + cyclohexanol + cyclohexanone, phenol + cyclohexanol + benzyl alcohol, and phenol + acetophenone + 1-propanol. It is shown that two binary constituents of the former two mixtures exhibit MaxFPB, while a single binary constituent of the latter mixture has MaxFPB. For all three studied mixtures, the maximum flash point of the solution is located at their one of the binary constituents. In general, the results provide a useful source of reference for hazard reduction, process safety design, and fuel design.
