PROCESS FOR PREPARING PEROXIDIC PERFLUOROPOLYOXYALKYLENES

摘要

The present invention relates to a process for the oxidation of tetrafluoroethylene at a temperature between -100 ° C and -40 ° C in the absence of ultraviolet radiation. The process is characterized in that at least one bond F-X, where X is preferably fluorine or alkyl, hypofluorite, is carried out in the presence of a chemical initiator at a pressure of between 105 Pa and 1.6 · 106 Pa in the presence of a solvent containing more than 8 mol%. It contains COF2 or in the presence of COF2 alone. ŕ
