Abstract/OtherAbstract:
Smog chamber/FTIR techniques were used to measure k(Cl + CHF(2)OCHF(2)) = (5.7 +/- 1.5) x 10(-16) cm(3) molecule(-1) s(-1) in 700 Torr of N(2)/O(2) diluent at 296 +/- 1 K. This result is 100 times lower than the previous literature value. The chlorine-atom-initiated atmospheric oxidation of CHF(2)OCHF(2) gives COF(2) in a molar yield of (185 +/- 22) %. The IR spectrum was recorded, and a radiative efficiency of 0.44 W m(-2) ppb(-1) was determined. The results are discussed with respect to the atmospheric chemistry and environmental impact of CHF(2)OCHF(2).
