Hexachloroethane is formed when tetrachloroethylene reacts with chlorine at 50–80 °C in the presence of a small amount of iron(III) chloride (0.1%) as a catalyst: [20] C 2 Cl 4 + Cl 2 → C 2 Cl 6. CFC-113 is produced by the reaction of tetrachloroethylene with chlorine and HF in the presence of antimony pentafluoride: [21] C 2 Cl 4 + 3 HF ...
