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.

Perfluorochemicals and process for preparing the same

The present invention relates to novel perfluoro chemicals (PFC), particularly perfluorocyclic ethers and polyfluorinated compounds containing a few chlorine atoms and to a method for the preparation thereof.

Perfluoro chemicals and polyfluorinated compounds

Novel persistent perfluorinated free radicals are disclosed, which upon thermal decomposition yield free radicals which can be used to polymerize polymerizable monomers containing ethylenic unsaturation.

Novel perfluoro chemicals and polyfluorinated compounds and process for

Novel fluorohydrocarbons include a fluoroalkyl unit terminating in a tertiary carbon atom which is directly linked to an aliphatic moiety of the compound. The compounds contain at least 9 carbon atoms and usually no more than 13 carbon atoms. The compounds are synthesized by addition of a fluoride atom to the tertiary carbon atom of a fluorocarbon material to form a carbanion followed by alkylation of the carbanion. The fluorohydrocarbons will find use as blood substitutes or as electronic fluids.
