1. A process comprising pyrolyzing at least one perfluorinated hydrocarbon, or a material containing at least one perfluorinated hydrocarbon, in a pyrolysis zone at a temperature between about 580 K and about 2000 K in the presence of hydrogen to yield a reaction mixture containing difluorocarbene, wherein the hydrogen is present in the pyrolysis zone in a molar ratio from about 0.1 to 8 mol hydrogen per mol of perfluorinated hydrocarbon. |
