| abstract |
The present invention provides a process for preparing a fluorine-containing propane represented by the formula: CF 2 XCF 2 CH 3 wherein X is F or Cl, the process including reacting tetrafluoroethylene and methyl chloride in the presence of an antimony halide represented by the formula: SbF x C 5-x wherein x is a value of 0 to 5. According to the present invention, the fluorine-containing propane represented by the formula: CF 2 XCF 2 CH 3 wherein X is F or Cl, which is useful as a starting material of 2,3,3,3-tetrafluoropropene (1234yf), can be obtained by a simple process, using relatively inexpensive starting materials. |
