METHOD FOR PRODUCTION OF 1,2-DICHLORO-3,3,4,4,5,5-HEXAFLUOROCYCLOPENTENE Russian patent published in 2008 - IPC C07C23/08 C07C17/20

Abstract RU 2318792 C2

FIELD: organic chemistry.

SUBSTANCE: claimed method includes interaction of octachlorocyclopentene with hydrogen fluoride or hexachlorocyclopentene and simultaneous interaction of formed octachlorocyclopentene with hydrogen fluoride. Process is carried out at elevated temperature (60-180°C) and pressure up to 25 kgf/cm² in presence of catalyst of general formula SbF_nCl_5-n, wherein n = 1 or 2 (including fractional numbers), obtained in situ in reactor by feeding of gaseous hydrogen fluoride through layer of SbCl₅.

EFFECT: high active catalyst, decreased equipment corrosion, increased product yield.
