A novel strategy for synthesis of dichlorooctafluorocyclopentane and reaction mechanism investigation

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(III), 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.

Synthesis of hydrofluorocyclopentanes by vapor-phase catalytic hydrodehalogenation

Hydrofluorocyclopentanes (c5-HFCs) were prepared by gas-phase hydrodehalogenation of chlorofluorocyclopentenes (c5-CFOs) over various noble metals catalysts. The activity of the catalysts followed the order Pd > Pt > Rh > Ru, and the halogen atom on the C(sp2) atom exhibited stronger reactivity than the halogen on the C(sp3) atom. Possible mechanisms of the gas-phase hydrodehalogenation of c5-CFOs re proposed herein.

Synthesis of 1,1,2,2,3,3,4-heptafluorocyclopentane as a new generation of green solvent

1,1,2,2,3,3,4-Heptafluorocyclopentane is a new generation of green solvent. It was synthesized by the liquid-phase fluorination reactions from hexachlorocyclopentadiene to 1-chloroheptafluoro-cyclopentene in the presence of KF in DMF and by the vapor-phase hydrogenation reaction from 1-chloroheptafluorocyclopentene to 1,1,2,2,3,3,4-heptafluorocyclopentane in the presence of Pd-based hydrogenation catalyst. Quantum chemical calculations for the isomers energies using Gaussian09 were conducted to verify the chemical equilibriums between isomers of trichloropentafluorocyclopentene or dichlorohexafluorocyclopentene in the fluorination reactions. Possible mechanisms for 1,1,2,2,3,3,4-heptafluorocyclopentane synthesis were proposed.

Porous calcium fluoride having a large surface area, a method for producing the same, a catalyst (for hydrogenation reaction in particular) using the porous calcium fluoride as a carrier with superior activity, selectivity, and durability, and a method for producing trihydrofluorocarbon using the catalyst. The porous calcium fluoride having a BET surface area of 20 m2/g to 200 m2/g is prepared by reacting soda lime with hydrogen fluoride. The carried cataryst (for hydrogenation reaction in particurar) is obtained by causing a metal or metal compound to be carried on carrier formed of the porous calcium fluoride. Trihydrofluorocarbon (2) is produced by causing a fluooroalkene (1) to contact hydrogen in the presence of the catalyst for hydrogenation reaction. wherein X denotes a halogen atom, Rf1 and Rf2 individually denote a fluorine or a parafluoroalkyl group, and Rf1 may be bonded to Rf2 to form a ring.
