Abstract
Abstract The reactions of 1,1,2-trichloro-1,2,2-trifluoroethane, CCl2FCClF2 (F113), were studied on three catalysts, Cr2O3 on active charcoal, AlF3 and Cr2O3 on AlF3, in the presence and absence of hydrogen fluoride. Without hydrogen fluoride two reactions occur, disproportionation (exchange of halogen) and isomerization. With hydrogen fluoride fluorination is the main reaction, the selectivity of which (symmetric or asymmetric compounds) is governed by the acidity of the catalyst.
