Isomerization reaction of dichlorotrifluoroethane

The invention discloses an isomerization reaction of dichlorotrifluoroethane. The reaction uses 2,2-dichloro-1,1,1-trifluoroethane as a raw material, and 1,2-dichloro-1,1,2-trifluoroethane (R123a) and1,1-dichloro-1,2,2-Trifluoroethane (R123b) are prepared under the action of an isomerization catalyst, wherein the isomerization catalyst is a mixture of AlF3 and AlCl3. The reaction has the advantages of simple process, strong operability, low cost, and the like.

Selective reduction of halopolyfluorocarbons by organosilicon hydrides

It is demonstrated that silicon hydrides can be used for reduction of polyfluorinated halocarbons. For example, the reaction between CF3CCl2F and excess triethylsilane, catalyzed by benzoyl peroxide, leads to the formation of a mixture containing CF3CHClF (major), CF3CH2F, and ClSi(C2H5)3. On the other hand, the reaction of chlorofluoroalkanes, containing an internal -CCl2- group readily proceeds with reduction of both chlorines, leading to compounds such as (CF3)2CH2 and CF3CH2C2F5. In contrast to chlorofluoroalkanes, bromofluoroalkanes are much more reactive and reaction with hydrosilane rapidly proceeds without the catalyst at elevated temperature.
