FLUORINATED ALKANESULFONIC ACID ANHYDRIDES AND PROCESSES FOR MAKING THE SAME

摘要

The invention provides a process for the preparation of fluorinated alkanesulfonic acid anhydrides by contacting alkanesulfonic acids with phosphorus pentoxide, the phosphorus pentoxide being provided as a dispersion in an inert oil. The invention also provides novel fluorinated alkanesulfonic acid anhydrides including 2-hydrotetrafluoroethanesulfonic acid anhydride.
