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.

Abstract: Aromatic hydrocarbons which have undergone nuclear substitution with a trifluoromethyl group are electrolytically fluorinated in anhydrous hydrogen fluoride. The mixed gas which is consequently formed is sent through the aqueous solution of sodium sulfite containing therein potassium iodide, thereafter cooled and collected, and subjected to refining treatment such as by trap-to-trap distillation, distillation, or gas chromatography to obtain perfluorocyclohexane derivatives.
