Abstract
FTIR smog chamber techniques were used to measure k(Cl + (CF3) 2CFOCH3) = (1.80 +/- 0.42) x 10(-13), k(Cl + (CF3) 2CFOCHO) = (1.47 +/- 0.56) x 10 x 14, and k(OH + (CF3) 2CFOCH3) = (1.55 +/- 0.24) x 10 14 cm3 molecule 1 s1. The chlorine-atom initiated oxidation of (CF3) 2CFOCH3 in air in the absence of NOX results in conversion of (CF3) 2CFOCH3 into the formate, (CF3) 2CFOCHO, in a yield indistinguishable from 100%. In the presence of NOX, the (CF3) 2CFOCHO yield was decreased by approximately 17%, which we attribute to the formation of peroxy and/ or alkoxy nitrates. The atmospheric lifetime of (CF3) 2CFOCH3 was estimated to 3.7 years. The infrared spectrum of (CF3) 2CFOCH3 was measured and a global warming potential GWP100 = 354 was determined.
