Non-enzymatic degradation of chlorofluorocarbon 113 using cyanocobalamin under anaerobic conditions

Chlorofluorocarbon 113 (CFC113) was rapidly and completely degraded non-enzymatically in systems containing cyanocobalamin with titanium (III) citrate as the reductant. Hydrochlorofluorocarbon 123a (HCFC123a) accounted for up to 25% of the degraded CFC113. Chlorotrifluoroethene was also detected. Increasing concentrations of cyanocobalamin increased CFC113 removal rates asymptotically and also decreased the fraction of HCFC123a remaining. Key words: chlorofluorocarbon 113, cyanocobalamin, anaerobic degradation, non-enzymatic.
