Abstract: Aromatic hydrocarbons such as, for example, trifluoromethyl benzonitrile and bis-(trifluoromethyl)-benzonitrile which are composed of benzene derivatives having nitrile and trihalogenated methyl substituted for hydrogens of benzene are dissolved in anhydrous hydrogen fluoride and the solutions are electrolyzed to produce perfluoro-alicyclic hydrocarbons composed of perfluorocyclohexane derivatives having trifluoromethyl substituted for fluorine of perfluorocyclohexane.
