THE EFFECT OF THE CATHODE MATERIAL ON THE ELECTROCHEMICAL ACTIVATION AND DEHALOGENATION OF C-2 FREONS

The effect of the cathode material (GC, Pt, Ag) on the electrophilic dehalogenation of C-2 Freons [F113 (CF2ClCFCl2), F113B2 (CF2BrCFClBr), and F114B2 (CF2BrCF2Br)] was studied. Such reactions lead to the formation of valuable chlorotrifluoro- or tetrachloroethylenes. It was found that a silver cathode has a promoting effect on the investigated processes compared with the other materials (GC, Pt). The optimum reaction conditions within the present investigation were determined.
