Usage

General Description

1-chloro-1,2,2-trifluoro-ethane is a colorless, odorless chemical compound that is commonly used as a refrigerant and as a solvent in the production of various chemicals. It is also known by its trade name Freon 113. This chemical is stable and non-flammable, making it a popular choice for use in industrial and commercial applications. However, it is considered to be an ozone-depleting substance and has been phased out of use in many countries in favor of more environmentally friendly alternatives. Due to its potential harm to the environment, 1-chloro-1,2,2-trifluoro-ethane is regulated under the Montreal Protocol, which aims to protect the ozone layer by phasing out the use of ozone-depleting substances.

METHOD FOR PRODUCING 1-CHLORO-1,2-DIFLUOROETHYLENE

The present invention provides a method for efficiently producing 1-chloro-1,2-difluoroethylene at low cost. Specifically, the present invention provides a method for producing 1-chloro-1,2-difluoroethylene, including the step of dehydrohalogenating chlorofluoroethane represented by formula (1) CFClX1—CHFX2 wherein X1 and X2 are different from each other and represent H, F, or Cl; and either X1 or X2 is H.

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.
