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 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.

METHOD FOR PRODUCING HYDROGEN-CONTAINING FLUOROOLEFIN COMPOUND

An unsaturated hydrogen-containing fluoroolefin compound is obtained by bringing an unsaturated fluorine-containing halogen compound into contact with 0.1 to 3 molar equivalents of hydrogen relative to the unsaturated fluorine-containing halogen compound in a vapor phase in the presence of a supported palladium catalyst in which an amount of supported palladium is 0.1% by weight to 2.5% by weight.
