    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 ...

  8. Isolation condenser - Wikipedia

    en.wikipedia.org/wiki/Isolation_condenser

    Steam enters the IC condenser and condenses until it is filled with water. When the IC system is activated, a valve at the bottom of the IC condenser is opened which connects to a lower area on the reactor. The water falls to the reactor via gravity, allowing the condenser to fill with steam, which then condenses.
