Electrically conductive water/oil microemulsions based on perfluorinated compounds

Abstract From the Canadian patent

An electrochemical process, in which a gaseous matter is reduced at the cathode and in which microemulsions of the water-in-oil (w/o) type are utilized as catholytes, said mocroemulsions having ionic electric transfer and matter interphase transfer capacities and in, which the oil phase consists of a perfluoropolyether having perfluoroalkyl end groups or functional end groups of the hydrophilic type, or of a perfluorocarbon said microemulsions being obtained by the use of perfluorinated surfactants, in particular of those having perfluoroalkylpolyethereal structure and/or by the use of an alcohol as a co-surfactant. * * * * * *
