STABILIZATION OF PERFLUOROCARBON EMULSIONS, AND PERFLUORINATED HETEROCYCLIC COMPOUNDS USABLE AS EMULSION-STABILIZING ADDITIVES

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.
