When used as a fire suppressant, hexafluoropropane carries the DuPont trade name, FE-36.
1,1,1,3,3,3-Hexafluoropropane is a greenhouse gas; its global warming potential is 6300.
It is manufactured by reacting 1,1,1,3,3,3-hexachloropropane with hydrogen fluoride in gas phase at temperature between 250-400 °C, in presence of a catalyst in the form of trivalent chromium (e.g. chromium(III) chloride) supported on carbon with low content of specific impurities.[3]
