Abstract
The electrochemical conversion of dichlorodifluoromethane (CFC-12) was studied on silver and lead electrodes. The main products detected were CHClF2, CH2F2, CH3F and CH4. Cyclic voltammetry and constant potential electrolytic experiments in acetonitrile showed that on silver the reduction mechanism starts with the elimination of one chloride ion at −1.05 V. The current density and the product distribution strongly depend on the nature of the electrolyte used. Higher current densities were observed in methanol and acetonitrile, whereas in propylene carbonate (PC) the current density was found to be 13 times lower than that in acetonitrile. This difference was mainly attributed to the differing diffusion coefficient of CFC-12 in various solvents. A consecutive reaction mechanism was proposed to explain the experimental results.
