Title:

METHOD FOR PRODUCING FLUORINE-CONTAINING FLUOROSULFONYL ALKYLVINYL ETHER

Document Type and Number:

WIPO Patent Application WO/2006/051697

Kind Code:

A1

Abstract:

Disclosed is a method for producing a fluorine-containing fluorosulfonyl alkylvinyl ether represented by the following chemical formula: CF₂=CFOCF₂CF₂SO₂F which is characterized in that a fluorine-containing chlorosulfonyl alkylvinyl ether represented by the following chemical formula: CF₂=CFOCF₂CF₂SO₂Cl is reacted with a fluorinating agent represented by the following chemical formula: KF·(HF)_n (wherein n represents a number of 0-5) in a polar organic solvent at a temperature not more than 70&ring C. With this method, a fluorine-containing fluorosulfonyl alkylvinyl ether can be commercially advantageously produced at low cost with high yield by a simple process.
