Scope

Scope: This document specifies the testing requirements for trifluoromethanesulfonic anhydride, including the test methods, inspection rules, and determination results for trifluoromethanesulfonic anhydride. This document is applicable to the determination of trifluoromethanesulfonic anhydride produced by the reaction of trifluoromethanesulfonic acid with phosphorus pentoxide using methanesulfonyl chloride and potassium fluoride as raw materials. The determination of trifluoromethanesulfonic anhydride produced by other processes can be referenced for implementation. Main technical contents: Determination of the content of trifluoromethanesulfonic anhydride, determination of the content of sulfate, determination of the content of fluoride ions, and determination of the content of trifluoromethanesulfonic acid and other fluorine-containing compounds.
