Abstract
Provided is a manufacturing method in which 1-chloroheptafluorocyclopentene is brought into contact with an alkali metal fluoride to obtain octafluorocyclopentene. The manufacturing method includes a fluorination step of maintaining, at 85° C. or higher, a suspension containing an alkali metal fluoride suspended in a mixed solvent including a polar aprotic solvent and a glycol ether having a higher boiling point than the polar aprotic solvent while supplying 1-chloroheptafluoropentene into the suspension and performing fluorination thereof to obtain octafluorocyclopentene.

A method of manufacturing octafluorocyclopentene by bringing 1-choroheptafluorocyclopentene into contact with an alkali metal fluoride to obtain octafluorocyclopentene, comprising:
- a fluorination step of maintaining, at 85° C. or higher, a suspension containing the alkali metal fluoride suspended in a mixed solvent including a polar aprotic solvent and a glycol ether having a higher boiling point than the polar aprotic solvent while supplying 1-chloroheptafluoropentene into the suspension and performing fluorination thereof to obtain octafluorocyclopentene;
- and
- a recovery step of recovering the octafluorocyclopentene that is produced in the fluorination step.
