Ferrocene-Containing Emulsion-Based Fire-Extinguishing Agents

抄録

This paper proposes a novel fire suppressant: a ferrocene-containing oil-in-water (O/W) emulsion. In this study, oil-in-water emulsions containing a surfactant (triton X-100) and ferrocene (0-500 ppm) were prepared and their stabilities and capabilities to extinguish pool fires were investigated. The resulting O/W emulsions exhibited no phase separation for at least one month. Suppression experiments clearly demonstrated that (1) the ferrocene-containing O/W emulsions have a high suppression capability even if the emulsion contained 1.05-wt% n-octane and that (2) the suppression capability is positively correlated with the ferrocene concentration in the 0-500 ppm concentration range.
