METHOD OF PRODUCING PERFLUORO-3-METHOXYPROPIONYL FLUORIDE Russian patent published in 2017 - IPC C25B3/08 C07C51/58 C07C53/50

Abstract RU 2615148 C1

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing perfluoro-3-methoxypropionyl fluoride which is the initial product of perfluoro-3-methoxypropyl vinyl ester (monomer M-60MP) production, which provides increased frost resistance to its copolymers-fluororubbers due to the decrease of their glass transition temperature. The method consists in the electrochemical fluorination of methyl 3-methoxytetrafluorinepropionate in liquid anhydrous hydrogen fluoride, wherein triallylamine is used as the electrolyte additive in an amount from 1.0 to 10.0 wt % of the total electrolyte weight.

EFFECT: method enables to obtain the end product with 60-65 percents of current output.
