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.
