Gas-phase reaction of Halon 1301 (CBrF3) with propane

Yu, H., Kennedy, E.M. and Dlugogorski, B.Z. (2002) Gas-phase reaction of Halon 1301 (CBrF3) with propane. Industrial & Engineering Chemistry Research, 41 (12). pp. 2858-2863.

The nonoxidative gas-phase reaction of Halon 1301 (CBrF3) with propane in a nitrogen bath was investigated using a tubular plug-flow reactor. Experiments were performed at atmospheric pressure, over a range of temperatures from 500 to 700 °C, and at residence times between 0.7 and 4 s. The pyrolysis of propane was also investigated to examine the effect of added Halon 1301 on the pyrolysis reaction. Experimental data suggest that CF3 and possibly Br radicals formed via the thermal cleavage of CBrF3 react with C3H8 and, at higher temperatures, with the decomposition products of C3H8. In addition to HBr, the major products formed during the reaction included CHF3, CH4, C2H4, C3H6, and H2. Minor product species including C2H2, C2H6, C3H4, HF, C2H3F3, C2H2F2, C3H3F3, and C2H3F were detected. Coke formation was also observed on the surface of the reactor.
