Method for synthesizing high-purity hexafluoro-1, 3-butadiene

The invention relates to a method for synthesizing high-purity hexafluoro-1, 3-butadiene, and belongs to the field of organic chemical synthesis. The method for synthesizing the hexafluoro-1, 3-butadieneI is characterized by comprising: heating hexachlorobenzene, chlorine and anhydrous hydrogen fluoride under the action of a catalyst to generate 1, 2-dichloro-3, 3, 4, 4, 5, 5, 6, 6-octafluorocyclohexene; heating the 1, 2-dichloro-3, 3, 4, 4, 5, 5, 6, 6-octafluorocyclohexene and a solvent under the action of a strong oxidant to generate 1, 6-octafluoroadipic acid; and finally, heating the 1, 6-octafluoroadipic acid and a solvent under the action of sodium hydroxide to generate sodium fluoride, water, carbon dioxide and hexafluoro-1, 3-butadiene, performing water removal and carbon dioxide removal treatment on the mixed gas to obtain the high-purity hexafluoro-1, 3-butadiene. The raw materials are cheap and convenient to obtain; the catalyst has good stability and long service life; theproduct separation and purification are simple; and industrial production is easy.
