  • Process for the preparation of halogenated ethanes
    Patent number: 6417413
    Abstract: A process for preparing halogenated ethanes, particularly pentafluoroethane, from a mixture produced by the reaction of perchloroethylene, hydrogen fluoride and a recycle stream. The preferred process utilizes phase separation techniques to ensure that less than the azzeotropic amount of HF is included in the product stream, thereby minimizing the hydrogen fluoride that is carried off with the desired products after they are separated from the reaction mixture, and at the same time prevents undesirable byproducts from being recycled to the reaction.
