Title:
METHOD FOR PRODUCING FLUORINATED FLUOROSULFONYLALKYL VINYL ETHER
Document Type and Number:
WIPO Patent Application WO/2007/142266
Kind Code:
A1
Abstract:
Disclosed is a method for producing a fluorinated fluorosulfonylalkyl vinyl ether represented by the following chemical formula: CF2=CF(CF2)aO(CF2CF(CF3)O)b(CF2)cSO2F (wherein a, b and c are as defined below) by reacting a fluorinated chlorosulfonylalkyl vinyl ether represented by the following chemical formula: CF2=CF(CF2)aO(CF2CF(CF3)O)b(CF2)cSO2Cl (wherein a represents 0 or 1, b represents an integer of 0-5 and c represents an integer of 1-10) with a fluorinating agent represented by the following chemical formula: MF•(HF)x (wherein M represents an alkali metal and x represents an integer of 0-5). This method for producing a fluorinated fluorosulfonylalkyl vinyl ether is characterized in that the reaction is carried out in the presence of 0.05-9 parts by weight of water per 100 parts by weight of the fluorinated chlorosulfonylalkyl vinyl ether as a raw material. This method enables to commercially advantageously produce a fluorinated fluorosulfonylalkyl vinyl ether with high selectivity and high yield by a simple process.
