✦ Synopsis

HFC-134a is an important chlorofluorocarbon replacement which degrades in the atmosphere to give CF 3 CFHO radicals. Hasson et al. [1] have studied the fluorine atom initiated oxidation of HFC-134a and reported values for the rate constant ratio k 1 /k 2 at 700 Torr total pressure and 298 -357 K.

Experiments have been carried out on the oxidation of CF 3 CFH 2 (HFC-134a). Reaction was initiated by continuous photolysis of F 2 in the near-ultraviolet. The F atoms produced abstracted a hydrogen atom from CF 3 CFH 2 initiating oxidation in gas mixtures containing O 2 and made up to a total pres
