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.
