HCCl 3 + 2 HF → HCF 2 Cl + 2 HCl. An important application of R-22 is as a precursor to tetrafluoroethylene. This conversion involves pyrolysis to give difluorocarbene, which dimerizes: [3] 2 CHClF 2 → C 2 F 4 + 2 HCl. The compound also yields difluorocarbene upon treatment with strong base and is used in the laboratory as a source of this ...
