PERFLUORINATED ORGANIC COMPOUND PRODUCTION PROCESS Russian patent published in 2004 - IPC

FIELD: industrial organic synthesis. SUBSTANCE: perfluorinated organic compounds for various applications are prepared by electrochemical fluorination of compounds selected from group including alkanesulfonyl chlorides, alkyl ethers, and aromatic compounds including in their molecules by at least one fluorine atom less than in perfluorinated derivative. Fluorination is carried out on nickel anodes in presence of organic electrolytic additive, in particular aliphatic, aromatic, or alkylaromatic amine in amount of 27-75% based on initial compound. More specifically, tertiary aliphatic amine has general formula (R_H)₃N, where R_H is saturated or unsaturated radical having 2-4 carbon atoms, e.g. ethyl, propyl, butyl, and propenyl, and aromatic amine has formula C₅H₅N. EFFECT: increased yield of product. 2 cl, 2 tbl
