Title:
METHOD FOR PRODUCING FLUOROVINYL ETHER COMPOUND
Document Type and Number:
WIPO Patent Application WO/2022/138659
Kind Code:
A1
Abstract:
Provided is a method for producing a fluorovinyl ether compound capable of suppressing the generation of by-products.　The method for producing a fluorovinyl ether compound of the present invention is a method for producing a fluorovinyl ether compound that heat treats a compound having a group represented by formula (1): F-C(=O)-CF-(X)-(CF2)n-O- in the presence of an oxide including at least one element selected from the group consisting of alkali metal elements and alkaline earth metal elements to obtain a fluorovinyl ether compound having a group represented by formula (2): CF2=CF-O-, the specific surface area of the oxide before heat treatment being 1.0 m2/g or more. In formula (1), n is 0 or 1. When n is 0, X is CF3; when n is 1, X is F.
