Removal of (hydro)haloalkene impurities from product streams |
摘要 |
A process for removing a (hydro)haloalkene impurity from a product stream containing that impurity and a desired compound is described. The process comprises contacting the product stream with a solid adsorbent comprising pores having openings which have a size across their largest dimension in the range of from about 7 Å to about 10 Å. The process is particularly suited to the removal of (hydro)halopropene impurities from saturated hydrofluorocarbons such as a tetrafluoroethane, a pentafluoropropane, a hexafluoropropane or a heptafluoropropane.
