Preparation method of hexafluoro-1,3-butadiene and intermediate thereof

The invention discloses a preparation method of hexafluoro-1,3-butadiene and an intermediate thereof, wherein the preparation method of hexafluoro-1,3-butadiene comprises the steps: A1, carrying out areaction on 1,2-dibromo-1-chloro-1,2,2-trifluoroethane with trifluorohaloethylene in a polar aprotic solvent under the action of an initiator, and rectifying and purifying a reaction solution to obtain 1,4-dibromo-2-chloro-3-halo-1,1,2,3,4,4-hexafluorobutane, wherein the structural formula of trifluorohaloethylene is CF2=CFX, X is Cl, Br or I, and the initiator is selected from at least one of azodiisobutyronitrile, di-tert-butyl peroxide, dibenzoyl peroxide, dicumyl peroxide, tert-butyl hydroperoxide, potassium persulfate and ammonium persulfate; and A2, carrying out dehalogenation reactionon 1,4-dibromo-2-chloro-3-halo-1,1,2,3,4,4-hexafluorobutane and zinc powder to obtain hexafluoro-1,3-butadiene. The preparation method has the advantages of simple process, mild reaction conditions, suitability for industrial production and the like.
