摘要: This method for producing trifluoromethanesulfonic anhydride reacting trifluoromethanesulfonic acid with phosphorus pentoxide to produce trifluoromethanesulfonic anhydride, wherein hardening of the reaction solution due to polyphosphoric acid, which is produced as a byproduct, is prevented by using an excess amount of trifluoromethanesulfonic acid with respect to the phosphorus pentoxide.
