  • PROCESS FOR PREPARING DECAFLUOROCYCLOHEXENE
    Publication number: 20100121117
    Abstract: Disclosed herein is a process of preparing decafluorocyclohexene using hexafluorobenzene as a raw material. The hexafluorobenzene reacts with an activated fluorinating agent at 60-200° C. in an inert gas atmosphere. The activated fluorinating agent is prepared by mixing 1-50 wt % of cobalt difluoride with 50-99 wt % of other metal fluoride selected from calcium fluoride, magnesium fluoride, aluminum fluoride, sodium fluoride and potassium fluoride. The mixture reacts with fluorine gas at 200-400° C.

  • METHOD AND APPARATUS FOR PREPARING TUNGSTEN HEXAFLUORIDE USING A FLUIDIZED BED REACTOR
    Publication number: 20100104497
    Abstract: Disclosed herein are a method of preparing tungsten hexafluoride (WF6) gas by fluidizing tungsten powder with inert gas in a reactor and fluorinating the fluidized tungsten powder with fluorine (F2) or nitrogen trifluoride (NF3) gas, and an apparatus (including fluidized bed reactor) for carrying out the method. The fluidized bed reactor shows a reaction efficiency of higher than 99% when being used to prepare tungsten hexafluoride.
