PROCESS FOR PURIFYING 1,1,1-TRIFLUORO-2,2-DICHLOROETHANE FROM ISOMER 1,1,2-TRIFLUORO-1,2-DICHLOROETHANE

摘要

The 1,1,2-trifluoro-1,2-dichioroethane content is reduced or removedfrom 1,1,1-trifluoro-2,2-dichloroethane by contacting a gaseous mixturecomprisingsaid compounds with chrome oxide (Cr2O3) either as such or supported, attemperatures from 180° to 400°C.
