Abstract: Disclosed is a method for producing 1,4-dibromo-2,3-dichlorohexafluorobutane (Br—CF2—CFCl—CFCl—CF2—Br), in which, through the photoreaction of 1,2-dibromo-1-chlorotrifluoroethane (Br—CF2-CFCl—Br) with a CTFE (CF2═CFCl) gas mixed with a diluent gas, 1,4-dibromo-2,3-dichlorohexafluorobutane is produced. According to an embodiment of the present disclosure, an intermediate for producing hexafluoro-1,3-butadiene (C4F6) can be produced with high production yield.
