摘要：

Kinetic study of the reactions of Cl atoms with EVE and PVE was performed using the absolute rate method over the temperature range 253-298 K at 1 Torr. The obtained Arrhenius expressions were k(EVE) = (8.0 +/- 1.4) x 10 (10)exp[(-349 +/- 21)/T] cm(3) molecule (1) s (1) and k(PVE) = (1.9 +/- 0.3) x 10 (9) exp[(-450 +/- 18)/T] cm(3) molecule (1) s (1). H-atom abstraction is likely to be the main reaction pathway as HCl was detected. The atmospheric lifetimes of EVE and PVE were evaluated, which demonstrates Cl atoms may play an important role for the sink of EVE and PVE. (C) 2009 Elsevier B. V. All rights reserved.
