Paragraph 0139-0144; 0152-0187, (2019/12/13)
The present invention relates to a method and an apparatus for manufacturing heptafluoroisopropyl trifluorovinyl ether. A manufacturing method and a manufacturing apparatus according to the present invention are possible to manufacture heptafluoroisopropyl trifluorovinyl ether having a high purity and a high yield. In addition, by adopting the method for manufacturing heptafluoroisopropyl tetrafluoropropinoyl fluoride, which has an intermediate having a high yield, there is an effect that a yield of an entire process comprising heptafluoroisopropyl trifluorovinyl ether as a final material can be improved.(S100) Step of reacting a metal fluoride with hexafluoroacetone in a solvent to prepare a heptafluoroisopropyl alkoxide metal salt(S200) Step of preparing heptafluoroisopropyl tetrafluoropropinoyl fluoride by cross-injecting hexafluoroacetone and hexafluoropropylene oxide to the heptafluoroisopropyl alkoxide metal salt(S300) Step of layer separating the heptafluoroisopropyl alkoxide metal salt and the prepared heptafluoroisopropyl tetrafluoropropinoyl fluoride(S400) Step of sending the heptafluoroisopropyl tetrafluoropropinoyl fluoride to the distillation column to undergo a distillation process(S500) Step of reacting the distilled heptafluoroisopropyl tetrafluoropropinoyl fluoride with a metal carbonate in a solvent to prepare a heptafluoroisopropyl tetrafluoropropinoyl acid metal salt(S600) Step of preparing a heptafluoroisopropyl trifluorovinyl ether through pyrolysis of the heptafluoroisopropyl tetrafluoropropinoyl acid metal salt;(S700) Step of sending the heptafluoroisopropyl trifluorovinyl ether to the distillation column to undergo a distillation processCOPYRIGHT KIPO 2020
