Study of Two Different Types of Minimum Flash-Point Behavior for Ternary Mixtures

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.
