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 O3 with trans-3,3,3-trifluoro-1-chloropropene,
t-CF3CH CHCl, in 700 Torr total pressure at 295±2K. Values of k(Cl + t-CF3CH CHCl) =
(5.22±0.72)×10-11 cm3 molecule-1 s-1, k(OH + t-CF3CH CHCl) = (4.40±0.38)×10-13 cm3 molecule-1 s-1
and k(O3 + t-CF3CH CHCl) = (1.46±0.12)×10-21 cm3 molecule-1 s-1, were established (quoted uncertainties
are 2; 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.
