| titleOfInvention | Method for producing fluorine-containing halogenated hydrocarbon |
| abstract | The present invention provides a method for producing a fluorinated halogenated hydrocarbon that avoids condensation during compression of HF of a raw material contained in an outlet gas. A method for producing a fluorinated halogenated hydrocarbon having a reaction step between a Cl-containing compound and HF, the production method comprising 2,3,3,3-tetrafluoropropene (HFO-1234yf), etc. A reaction product containing a fluorinated halogenated hydrocarbon, HF and HCl is separated in the following steps (1) to (5). (1) Separation of reaction product into gas phase and liquid phase 1 (2) Step 2 of pressurizing and feeding the liquid phase to distillation column A (3) Step 3 of compressing and feeding the gas phase to distillation column A ( 4) Separating a first stream containing HCl from the top of the distillation column A, and fractionating a second stream containing organic matter and HF from the bottom of the column. 4 (5) In the step 3, a compressor is used when compressing the gas phase. Is compressed in two or more stages in series, and the gas fraction of the compressed gas in each stage is maintained at 1 by heating with a heater. [Selection] Figure 1 |
