METHOD OF SYNTHESIS OF 1,1,1,2,3,3,3-HEPTAFLUOROPROPANE Russian patent published in 2001 - IPC

Abstract RU 2165918 C2

FIELD: organic chemistry, chemical technology. SUBSTANCE: invention relates to method of synthesis of 1,1,1,2,3,3,3-heptafluoro-propane involving hydrofluorination of hexafluoropropylene with hydrogen fluoride at enhanced temperature in the presence of catalyst and isolation of the end compound by the known procedures. Hydrofluorination process is carried out under adiabatic conditions and activated carbon with ash content 10 wt.-%, not less, is used as catalyst. EFFECT: improved method of synthesis, decreased exhaust of hydrogen fluoride. 3 cl, 1 tbl, 6 ex
