Abstract: Partially chlorinated ethers are electrolytically fluorinated in anhydrous hydrogen fluoride. The gas which is produced consequently is passed through water and the aqueous solution of sodium sulfite-sodium hydroxide for the removal of by-products and thereafter cooled and collected. The collected product is a mixture consisting of fluorinated ethers and fluorocarbons. Chlorofluoroethers which the present invention aims to obtain are separated from this mixture by additional treatments of distillation, gas chromatography, etc.

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.
