Abstract :
Long path length FTIR-smog chamber techniques were used to determine k(Cl + CF3CFCH2) = (7.03 ± 0.59) × 10−11, k(OH + CF3CFCH2) = (1.05 ± 0.17) × 10−12, and k(O3 + CF3CFCH2) = (2.77 ± 0.21) × 10−21 cm3 molecule−1 s−1 in 700 Torr of N2, N2/O2, or air diluent at 296 K. CF3CFCH2 has an atmospheric lifetime of approximately 11 days and a global warming potential (100 yr time horizon) of four. CF3CFCH2 has a negligible global warming potential and will not make any significant contribution to radiative forcing of climate change.
