Atmospheric chemistry of CF3CF=CH2:: Kinetics and mechanisms of gas-phase reactions with Cl atoms, OH radicals, and O3

Long path length FTIR-smog chamber techniques were used to determine k(Cl + CF3CF=CH2) = (7.03 +/- 0.59) x 10(-11) k(OH + CF3CF=CH2) = (1.05 +/- 0.17) x 10(-12), and k(O-3 + CF3CF=CH2) = (2.77 +/- 0.21) x 10(-21) cm(3) molecule' s(-1) in 700 Torr of N-2, N-2/O-2, or air diluent at 296 K. CF3CF=CH2 has an atmospheric lifetime of approximately 11 days and a global warming potential (100 yr time horizon) of four. CF3CF=CH2 has a negligible global warming potential and will not make any significant contribution to radiative forcing of climate change. (c) 2007 Elsevier B.V. All rights reserved.
