Abstract:
Researchers in the 1960's discovered that certain
metallic compounds are even more effective flame
inhibitors than the halogens. In particular, iron
pentacarbonyl was found to be up to two orders of
magnitude more effective at reducing the burning
velocity of hydrocarbon-air flames than Br-containing
compounds. However, the rapid adoption of CF3Br as a
fire suppressant led to a reduction in research on other
agents, and the inhibition mechanism of Fe(CO)5 remained
undetermined. As part of the search for replacements for
CF3Br, the mechanism of FE(CO)5 is being re-examined.
