METHOD OF POLYCHLORINATED DIPHENYL CHEMICAL PROCESSING Russian patent published in 1997 - IPC

Abstract RU 2087458 C1

FIELD: chemical technology. SUBSTANCE: method is based on reaction of fluorination of chlorine-containing organic compounds with alkaline metal fluorides, mainly, potassium fluoride. As result, polyfluorine-containing diphenyls were formed and chlorine binds to nontoxic alkaline metal chlorides. The obtained polyfluoro-containing diphenyls can be used as heat carriers and insulating materials. EFFECT: improved method of processing and detoxication. 5 cl, 3 tbl
