There is provided a novel perfluorochemical represented by the formula, ##STR1## wherein R.sub.F is a perfluoroalkyl group, a perfluoro alkoxyalkyl group or a perfluoroalkyloxy group, X and X' are same as or different from each other and are a fluorine atom or a perfluoroalkyl group, and Y is a perfluoroalkyloxy group or a perfluoro dialkylamino group, the total number of the carbon atoms contained being an integer of 8 to 11 inclusive. The perfluorochemical is prepared by perfluorinating the corresponding partially fluorinated compound which may have unsaturated hydrocarbon moiety, only with molecular fluorine in a stoichiometric excess amount in an inert solvent. The perfluorochemical is used for preparing a stable emulsion as blood substitutes or perfusion media.
提供了一种新型的全氟化合物,其化学式为##STR1##其中R.sub.F是全氟烷基基团、全氟烷氧烷基基团或全氟烷氧基基团,X和X'相同或不同且为氟原子或全氟烷基基团,Y为全氟烷氧基基团或全氟二烷基氨基基团,所含碳原子的总数为8至11的整数。该全氟化合物是通过在惰性溶剂中使用分子氟在化学计量过量量下对应的部分氟化化合物进行全氟化制备而成,该部分氟化化合物可能具有不饱和碳氢基团。该全氟化合物用于制备稳定的乳状液,作为血液替代品或灌注介质。
