Abstract
Provided is a method of manufacturing octafluorocyclopentene by bringing 1-chloroheptafluorocyclopentene into contact with an alkali metal fluoride. The manufacturing method includes a feedstock heating step of heating 1-chloroheptafluorocyclopentene to not lower than 40° C. and not higher than 55° C. and a fluorination step of maintaining a suspension containing a polar aprotic solvent and an alkali metal fluoride at 85° C. or higher while supplying heated 1-chloroheptafluorocyclopentene into the suspension and performing fluorination thereof to obtain octafluorocyclopentene.
Claims3
A method of manufacturing octafluorocyclopentene by bringing 1-chloroheptafluorocyclopentene into contact with an alkali metal fluoride, comprising:
- a feedstock heating step of heating 1-chloroheptafluorocyclopentene to not lower than 40° C. and not higher than 55° C.;
- a fluorination step of maintaining a suspension containing a polar aprotic solvent and the alkali metal fluoride at 85° C. or higher while supplying heated 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.
