摘要：

The kinetics of the reactions of O-3 with 3-bromopropene and 3-iodopropene has been studied over the temperature range of 288-328 K at atmospheric pressure. The results obtained for the room temperature rate constants are (1.88 +/- 0.22) x 10(-18) and (3.52 +/- 0.43) x 10(-18) cm(3) molecule(-1) s(-1), and the proposed Arrhenius expressions are k = (3.47 +/- 1.28) x 10(-15) exp[(-2233 +/- 110)/T] and k = (8.17 +/- 2.12) x 10(-14) exp[(-2991 +/- 80)/T] cm(3) molecule(-1) s(-1) for 3-bromopropene and 3-iodopropene, respectively. The atmospheric chemical lifetimes of these two compounds with O-3 were also estimated from these values. (C) 2009 Elsevier Ltd. All rights reserved.
