METHOD FOR PREPARING PERFLUOROALKANE SULFOFLUORIDE Russian patent published in 2004 - IPC

Abstract RU 2237659 C1

FIELD: organic chemistry, chemical technology.

SUBSTANCE: invention relates to a method for preparing derivatives of perfluoroalkane sulfofluoride using as intermediate compounds, for example, in synthesis of perfluoroalkane sulfoacids and their salts as components of scrubbing gas eliciting high etching rate index. Perfluoroolefin is treated with sulfuric anhydride at temperature 45-85^oC to yield perfluoroalkane sulfone and the latter is subjected for hydrolysis and prepared monohydroperfluoroalkane sulfofluoride is fluorinated with elementary fluorine at temperature 0-30^oC. Method provides preparing the end product with high yield.

EFFECT: improved preparing method.
