Cyclization processes in pyrolysis of perfluorooxaalkanedicarboxylic acid derivatives

Formation of cyclic structures under the conditions of pyrolytic decarboxylation of perfluorooxaalkanedicarboxylic acids was studied.

Process for producing perfluorovinylcarboxylic acid ester

The present invention relates to a method for producing a perfluorovinylcarboxylic acid ester by reacting a perfluorovinylcarboxylic acid salt with an alkylating agent. The present invention provides a method to produce perfluorovinylcarboxylic acid ester, which is used as a raw material of an ion-exchange membrane for the chloro alkali process, in high yield from starting material, a compound which can be easily produced, in a simple manner.

Process for producing fluorinated vinyl ether

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: wherein X is —CO2R or —SO2F, and R is an alkyl group.

Synthesis of perfluorinated vinyl ethers having ester group

A new efficient and convenient synthetic process of perfluorinated vinyl ethers containing an ester group was developed by pyrolysis in the presence of α-trifluoromethyl moiety without loss of -COF functional group followed by alcoholysis in high yield.
