Аннотация:Hydrofluoroethers (HFEs), as a class, are very promising candidates for substitution ozone-depleting solvents not only because of their zero ozonedepleting potentials, but also because they exhibit superior solvent properties. The reversible addn. of fluoride-ion to anhydrides of perfluoronated acids leads to formation of perfluoroalkoxy anions. We used both C8F17COOH and C3F7COOH as the sources of perfluorinated O-anions. The corresponding chlorides were obtained from these acids by the action of PCl5. For alkylation of O-anions we used the set of alkylating agents. We assumed that C8F17...
