The products of the Cl-atom initiated reactions of a series of hydrofluorocarbons (HFCs) and hydrochlorofluorocarbons (HCFCs) in air have been investigated at 298 K and one atmosphere (740 Torr total pressure) of air. The products observed and quantified and their yields (%) were as follows: from CHF2Cl (HCFC-22), C(O)F2 (100%); from CHFCl2 (HCFC-21), C(O)FCl (100%); from CH2FCl (HCFC-31), HC(O)F (100%); from CH3F (HFC-41), HC(O)F (100%); from CH3CFCl2 (HCFC-141b), C(O)FCl (100%); from CH3CF2Cl (HCFC-142b), C(O)F2 (100%); from CH3CHF2 (HFC-152a), C(O)F2 (92%); from CHCl2CF3 (HCFC-123), CF3C(O)Cl (98%); from CHFClCF3 (HCFC-124), CF3C(O)F (101%); and from CHF2CF3 (HFC-125), C(O)F2 (∼100%). The reaction mechanisms are discussed.
