Methods for producing perfluoromethyl vinyl ether and intermediate thereof

The invention discloses a method for producing perfluorinated-2-methoxy propionyl fluorine. In the presence of a polar aprotic solvent, under the action of a main catalyst alkali metal fluoride and a phase transfer catalyst, carbonyl fluoride and hexafluoropropylene oxide react to prepare perfluorinated-2-methoxy propionyl fluorine. The invention further provides a method for preparing perfluoromethyl vinyl ether from perfluorinated-2-methoxy propionyl fluorine. According to the methods, the reaction yield is high, the prepared products are high in purity, operation is easy, and environment friendliness is achieved.

PRODUCTION METHOD OF FLUOROETHERCARBOXYLIC ACID FLUORIDE AND FLUOROETHERCARBOXYLIC ACID

The present invention is a production method of a fluoroethercarboxylic acid fluoride, comprising the step of selectively producing a fluoroethercarboxylic acid fluoride represented by the formula (I): CF3O(CF(CF3)CF2O)CF(CF3)COF (I) by reacting hexafluoropropylene oxide with carbonyl fluoride in a solvent at a temperature of -30 to 40 °C in the presence of a catalyst, wherein the catalyst comprises at least one species selected from the group consisting of metal fluorides, tertiary amines, tertiary diamines and tetraalkylammonium salts, and the solvent is an aprotic polar solvent.
