N2 - Long path length Fourier transform infrared (FTIR)-smog chamber techniques were used to study the kinetics of the gas-phase reactions of Cl atoms. OH radicals and O-3 with trans-3,3,3-trifluoro-1-chloropropene, t-CF3CH = CHCl, in 700Torr total pressure at 295 +/- 2 K. Values of k(Cl + t-CF3CH = CHCl) = (5.22 +/- 0.72) x 10(-11) cm(3) molecule(-1) s(-1), k(OH + t-CF3CH = CHCl) = (4.40 +/- 0.38) x 10(-13) cm(3) molecule(-1) s(-1) and k(O-3 + t-CF3CH = CHCl) = (1.46 +/- 0.12) x 10(-21) cm(3) molecule(-1) s(-1), were established (quoted uncertainties are 2 sigma: see Experimental section). The IR spectrum of t-CF3CH = CHCl is reported. The atmospheric lifetime of t-CF3CH = CHCl is determined by reaction with OH radicals and is approximately 26 days. The global warming potential of t-CF3CH = CHCl is approximately 7 for a 100-year time horizon. (C) 2008 Elsevier B.V. All rights reserved.
