| titleOfInvention | Method for producing fluoroalkanesulfonic anhydride |
| abstract | Disclosed is a method for producing a fluoroalkanesulfonic anhydride, which is characterized by that a reaction is conducted while kneading a fluoroalkanesulfonic acid and diphosphorus pentoxide at a temperature that is 40 °C or higher and is lower than 100 °C by using a kneader-type reactor having a maximum power of 1.0 kW or greater per an actual capacity of 100 L and equipped with at least two-shaft blades, that the fluoroalkanesulfonic anhydride to be generated is discharged, and that, while the residue in the reactor after the discharge is kneaded at a temperature that is 100 °C or higher and is lower than 140 °C, the unreacted fluoroalkylsulfonic acid is discharged, recovered and reused as the raw material. It is possible by this method to obtain a fluoroalkanesulfonic anhydride with a high yield. |
