| titleOfInvention | Method for producing fluorine-containing halogenated hydrocarbon |
| abstract | A method for producing a fluorinated halogenated hydrocarbon having a step of compressing an outlet gas of a fluorination reactor with a compressor, avoiding condensation of hydrogen fluoride contained in the outlet gas during compression, Provided is a production method for stably obtaining a target compound. A method for producing a fluorinated halogenated hydrocarbon comprising a step of reacting a chlorine-containing compound and hydrogen fluoride in a gas phase state, comprising: The production method includes a separation step of separating a reaction product containing the organic substance containing the fluorine-containing halogenated hydrocarbon, hydrogen fluoride, and hydrogen chloride into a plurality of components, The fluorine-containing halogenated hydrocarbons are 1,1,1,2,2-pentafluoropropane (HFC-245cb), 1,1,1,3,3-pentafluoropropane (HFC-245fa), E, Z -1,3,3,3-tetrafluoropropene (E, Z-HFO-1234ze), 2,3,3,3-tetrafluoropropene (HFO-1234yf), 2-chloro-3,3,3-tri At least one selected from the group consisting of fluoropropene (HCFO-1233xf) and 1-chloro-3,3,3-trifluoropropene (HCFO-1233zd), The separation step is (1) Step 1 for separating the reaction product into a gas phase and a liquid phase, (2) Step 2 of increasing the pressure of the liquid phase and supplying it to the distillation column A, (3) Step 3 of compressing and supplying the gas phase to the distillation column A, and (4) separating the first stream containing the hydrogen chloride from the top of the distillation column A and from the bottom of the distillation column A. Separating the second stream containing the organic matter and the hydrogen fluoride, (5) In the step 3, when compressing the gas phase, the gas phase is compressed in two or more stages in series using a compressor, and heated with a heater, and the gas gas after compression in each stage Keep the fraction at 1, The manufacturing method characterized by the above-mentioned. [Selection figure] None |
