Halon molecule
Webhalon. halon Any of several organic gases used in fire extinguishers, but banned in 1994 because they destroy the ozone layer. Chemically halons can be considered as simple hydrocarbons that have had some or all of their hydrogen atoms replaced by a halogen. Similar to chlorofluorocarbons (CFCs), they are even more destructive to the ozone layer. Webgas phase reaction of Halon 121 1 at elevated temperatures, using methane as a hydrogen source was studied. Methane is available at relatively low cost in natural gas, and is an excellent hydro- gen source since one molecule of methane can offer up to four hydrogen atoms per reacting halon molecule [I 13.
