Emulsion stabilizing additive in aqueous emulsion, aqueous substitute for blood substitute, perfluorinated heterobicyclic compound and process for producing the same

摘要

The use of perfluorinated heterocyclic compounds of the general formula I, IMAGE I wherein n represents 2-8, X and Y represent a -CF2OCF2- group, a -CF2-CF2-CF2- group or a -CF(CF3)-CF2- group, and Y is a -CF2-O-CF2- group, a -CF(CF3)-CF2- group or a -CF2-CF2-CF2- group, or mixtures thereof, is described as emulsion-stabilizing additives in medically usable aqueous emulsions of perfluorocarbons, optionally containing hetero atoms, suitable for use in blood substitutes. The compounds are obtained by electrochemical perfluorination.
