Definitions
- the present invention uses CFC or HC as refrigerant, mk washing ⁇ I
- a method for producing 1,1,1,3,3-pentafluoroprop mouth bread is as follows: 1,2,3-trichloromouth 1,1,1,3,3-pentafluoropropane is used as a raw material and a palladium catalyst is used. There is known a method of performing hydrogen reduction using thiophene (US Pat. No. 2,942,036).
- 1,1,3,3,3-pentafluoropropene is a useful compound that can be used not only as a raw material for HFC blowing agents that do not destroy the ozone layer, but also as a raw material for various resins or drug intermediates. It is.
- a method of decarboxylation of ⁇ -hydroperfluoroisobutyrate potassium salt is also known, but this method not only makes it difficult to obtain raw materials but also industrially performs a decarboxylation reaction. (Synthesis of Fluoroorganic Compounds, IL Knunyants and GG Yakobson, Springer—Verlag, Berlin, Heidelberg, P8 (1985)).
- An object of the present invention is to provide a production method for obtaining 1,1,1,3,3-bentafluorop ⁇ -pan with high yield from 1,1,3,3,3-pentafluo ⁇ -propene as a raw material. It is in.
- Another object of the present invention is to produce 2-chloro-1,1,3,3,3-pentafluoropropene as a raw material and obtain 1,1,1,3,3-pentafluorofluoride in good yield.
- the object of the present invention is to provide a manufacturing method for obtaining rob mouth bread and Z or 1,1,1,3,3,3-pentafluoropropene.
