摘要： The disclosure relates to removing impurities from hexafluoroethane (CF3CF3), also known as Perfluorocarbon 116 (PFC-116) or Fluorocarbon 116 (FC-116), by using azeotropic distillation such that an overhead product consisting essentially of HCl-hexafluoroethane is formed, optionally combined with a phase separation step to break the HCl-hexafluoroethane azeotropic or azeotrope-like composition thereby permitting recovery of substantially pure hexafluoroethane. Unreacted hydrogen fluoride (HF) may be removed from hexafluoroethane during the above azeotropic distillation with HCl or alternatively by an azeotropic distillation wherein an HF-hexafluoroethane azeotropic or azeotrope-like composition exits overhead and substantially pure HF exits in the bottoms stream.
摘要翻译： 本公开涉及通过共沸蒸馏从六氟乙烷（CF 3 CF 3）（也称为全氟化碳116（PFC-116）或氟碳116（FC-116））除去杂质，从而形成基本上由HCl-六氟乙烷组成的塔顶馏出物 结合相分离步骤以破坏HCl-六氟乙烷共沸或类共沸组合物从而允许回收基本上纯的六氟乙烷。 在HCl的上述共沸蒸馏过程中，可以从六氟乙烷中除去未反应的氟化氢（HF），或者通过共沸蒸馏除去六氟乙烷，其中HF-六氟乙烷共沸或类共沸组合物离开塔顶馏出物，基本上纯的HF在塔底物流中离开。
