✦ Synopsis

The rate constant for the reaction of the hydroxyl radical with 1,2,2-trifuoroethane has been determined over the temperature range 278-323 K using a relative rate technique. The results provide a value of

for the rate constant of the reference reaction.

The chlorine atom initiated photooxidation of CHzCHFz was investigated from 255 to 330 K and as a function of 0 2 pressure at 1 atmosphere total pressure using Fourier transform infrared spectroscopy. The major carbon-containing products were CHFO and CF20 suggesting that the alkoxy radicals CHzFCFzO and CHFzCHFO, formed in the reaction, react predominantly by carbon-carbon bond cleavage. The results indicate that formation of CHFzCFO from the reaction of CHFzCHFO radicals with 0 2 will be unimportant under all atmospheric conditions.
