The Research Progress of Hexafluorobutadiene Synthesis

“…Miller [13] reacted 1,2-difluoro-dichloroethylene with fluorine under 0.9 to 1.0 MPa at room temperature for 26 h, then1,2,3,4-tetrachloro-hexafluorobutane was obtained directly and the yield was about 51% (mol). Thereafter, the above product and zinc powder were mixed in the diethylene glycol monobutyl ether, and the 1,2,3,4-tetrachloro-hexafluorobutane was dechlorinated directly to prduce hexafluorobutadiene.…”

“…William. T. Miller [13] decomposed trifluorochloroethylene in Pyrex tube under normal pressure at 550˚C to generate l,2-dichloro-hexafluorocyclobutane and 3,4-dichloro-hexafluoro-1-butene，the conversion was about 36.2%. Because of having similar boiling point, the above products were directly added into a glass tube without separation to react with liquid chlorine.…”
