| 20100121117 | PROCESS FOR PREPARING DECAFLUOROCYCLOHEXENE - 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. | 05-13-2010 |
| 20100121116 | PROCESS FOR PREPARING OCTAFLUOROCYCLOHEXADIENE - 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. | 05-13-2010 |
