METHOD FOR PRODUCTION OF 2,5-DI(TRIFLUOROMETHYL)-3,6-DIOXA-8-SULFONYLFLUORIDEPERFLUOROOCTANOYL FLUORIDE Russian patent published in 2006 - IPC C07C309/82 C07C303/02

Abstract RU 2269513 C1

FIELD: organic chemistry, in particular fluoropolymers for ion-exchange membranes.

SUBSTANCE: claimed method includes reaction of fluorosulphonyldifluoroacetyl fluoride with hexafluoropropylene oxide in presence of potassium fluoride in diglym (diethylene glycol dimethyl ether) medium. Then organofluoride layer is separated from diglym and rectified to isolate fraction boiling at temperature from 87 to 90°C under atmospheric pressure. Said fraction is reacted with hexafluoropropylene oxide in presence of potassium fluoride in diglym (diethylene glycol dimethyl ether) medium. Formed organofluoride product is separated from diglym, rectified together with residue after isolation of fraction boiling at 87-90°C under atmospheric pressure and target product is recovered. Compound of present invention represents intermediate for synthesis of fluorovinyl monomers useful in production of abovementioned fluoropolymers.

EFFECT: method for production of target product with increased yield.
