Title:
METHOD FOR PRODUCING FLUORINATED SULFONIC ACID ANHYDRIDE
Document Type and Number:
Japanese Patent JP2022139235
Kind Code:
A
Abstract:
To provide a method for producing a fluorinated sulfonic acid anhydride (2) that is useful as pharmaceuticals, catalysts for organic synthesis and the like, or synthetic materials, the method capable of suppressing consolidation in a reaction between a fluorinated sulfonic acid and diphosphorus pentoxide, achieving a high yield.SOLUTION: A method for producing a fluorinated sulfonic acid anhydride (2) causes a fluorinated sulfonic acid (1) to react with diphosphorus pentoxide in coexistence with silica.SELECTED DRAWING: None
