tial . However, questions have been raised concerning the environmental impact of trifluoroacetic acid which is formed from HFC-134a in the atmosphere as a result of the following reaction sequence [7 -10]. (1) (2) (3) (4) Reaction (4) produces CF 3 C(O)F which is hydrolyzed to CF 3 COOH after u
## Abstract Smog chamber/FTIR techniques were used to study the Cl atom initiated oxidation of CH~2~FOCH~2~F in 700 Torr of N~2~/O~2~ at 296 K. Relative rate techniques were used to measure __k__(Cl + CH~2~FOCH~2~F) = (4.6 Β± 0.7) Γ 10^β13^ and __k__(Cl + CH~2~FOC(O)F) = (2.9 Β± 0.8) Γ 10^β15^ (in un
