(EN) Perfluoroalkylorthocarbonates and perfluoropolyalkoxypropanes are disclosed. The perfluoro compounds are synthesized by direct fluorination procedures. The perfluoro compounds are useful lubricants, heat exchangers, vapor phase soldering fluids, solvents, and oxygen carriers.(FR) On décrit des perfluoroalkylorthocarbonates et des perfluoropolyalkoxypropanes. Les composés perfluoro sont synthétisés par des procédés de fluorination directe. Les composés perfluoro sont utiles en tant que lubrifiants, échangeurs thermiques, fluides de soudage en phase de vapeur, solvants et porteurs d'oxygène.

batch, photo-assisted directfluorination to give high yields of isomerically pure perfluorinated ethers. In a second scheme we use ethylene oxide to fine-tune the molecular weight of the polyol, and the weight of these can be extended by reaction with an appropriate fluoro-olefin. These intermediates can be fluorinated using our batch fluorinator to make new perfluorinated ethers of a specific molecular
