• 1,1-Dichlorooctafluorocyclopentane
• 1,2-Dichlorooctafluorocyclopentane
• Vapor-phase fluorination reaction
• Reaction mechanism

A novel method was used for preparing 1,1-dichlorooctafluorocyclopentane and 1,2-dichlorooctafluorocyclopentane through the reaction of 1,2-dichlorohexafluorocyclopentene, anhydrous hydrogen fluoride, and chlorine. A series of single- and multi-component catalysts were prepared by means of impregnation and coprecipitation, respectively. The catalyst containing Fe(Ill), Zr(IV), Co(II), Zn(II) and Cu (II) showed the highest catalytic activity among these catalysts. Moreover, the main reaction routes and catalytic mechanism were investigated through experiments and theoretical analysis. Given the environmental and economic benefits, this method has a great application potential in industrial production.
