Abstract
There is provided a process for producing a fluorinated vinyl ether from a fluorinated acid fluoride compound having an ester group as a precursor of a carboxylic acid group, or a SO2F group as a precursor of a sulfonic acid group, in high yield by simple operations. Said process is a production process comprising pyrolyzing a carboxylic acid potassium salt with a specific structure represented by the following formula in the absence of a solvent and/or while maintaining the salt in the solid state: 1 wherein X is —CO2R or —SO2F, and R is an alkyl group.
