Binary mixtures exhibiting minimum flash point behavior (MinFPB) are more hazardous than their pure, individual components. In real processes, multicomponent solutions are more frequently encountered than binary systems, but analyses of MinFPB for multicomponent mixtures are very rare. We investigated the MinFPB of ternary mixtures, with two minimum flash point binary mixtures, including isopropyl alcohol + ethanol + octane and 2-butanol + ethanol + octane (and their component binary combinations), and one ternary mixture, cyclohexanol + ethanol + octane, with a single binary mixture exhibiting MinFPB, and its component binary mixtures. Two different types of MinFPB were observed for the three ternary solutions, one with two constituent binary mixtures exhibiting MinFPB and one with a single binary mixture exhibiting MinFPB.
