Abstract: Disclosed herein is a process of preparing octafluorocyclohexadiene 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 1-10 wt % of cobalt difluoride with 90-99 wt % of other metal fluoride selected from the group of calcium fluoride, magnesium fluoride, aluminum fluoride, sodium fluoride and potassium fluoride. The mixture reacts with fluorine gas at 200-400° C.

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.

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.

Abstract: The method of preparing a chromium oxide catalyst for preparation of pentafluoroethane using a chloroethane compound includes heat treating chromium hydroxide powder at a temperature not higher than 300° C. to obtain chromium oxide powder, heat treating metal hydroxide, at a temperature not higher than 300° C. to obtain metal oxide powder, mixing 85˜99.5 wt % of the chromium oxide powder with 0.5˜15 wt % of the metal oxide powder to obtain a mixture, forming the mixture into a pellet, calcining the pellet at 200-300° C. using nitrogen gas, and fluorinating the pellet at 300-320° C. using a gas mixture including N2 and HF, and then at 320-380° C. using HF gas. The fluorination catalyst prepared using the method of this invention can be effectively used to prepare pentafluoroethane at a high yield using a chloroethane compound.
