Title:

PROCESS FOR PRODUCING FLUORINATED VINYL ETHER

Document Type and Number:

WIPO Patent Application WO/2003/002506

Kind Code:

A1

Abstract:

A process for producing a fluorinated vinyl ether through a simple procedure in high yield from a fluorinated acid fluoride compound having an ester group, which is a precursor for a carboxy group, or an SO₂F group, which is a precursor for a sulfo group. The process comprises thermally decomposing a carboxylic acid potassium salt having a specific structure represented by the following formula in the absence of a solvent and&sol or while keeping the salt in a solid state. (1) (In the formula, X is −CO₂R or −SO₂F and R is alkyl.)
