Atmospheric chemistry of trans-CF3CHCHCl: Kinetics of the gas-phase reactions with Cl atoms, OH radicals, and O3
چکیده انگلیسی

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-chloro-propene, t-CF3CHCHCl, in 700 Torr total pressure at 295 ± 2 K. Values of k(Cl + t-CF3CHCHCl) = (5.22 ± 0.72) × 10−11 cm3 molecule−1 s−1, k(OH + t-CF3CHCHCl) = (4.40 ± 0.38) × 10−13 cm3 molecule−1 s−1 and k(O3 + t-CF3CHCHCl) = (1.46 ± 0.12) × 10−21 cm3 molecule−1 s−1, were established (quoted uncertainties are 2σ; see Experimental section). The IR spectrum of t-CF3CHCHCl is reported. The atmospheric lifetime of t-CF3CHCHCl is determined by reaction with OH radicals and is approximately 26 days. The global warming potential of t-CF3CHCHCl is approximately 7 for a 100-year time horizon.
