Kinetic studies of O3 reactions with 3-bromopropene and 3-iodopropene in the temperature range 288–328 K

The kinetics of the reactions of O3 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) × 10−18 and (3.52 ± 0.43) × 10−18 cm3 molecule−1 s−1, and the proposed Arrhenius expressions are k = (3.47 ± 1.28) × 10−15 exp[(−2233 ± 110)/T] and k = (8.17 ± 2.12) × 10−14 exp[(−2991 ± 80)/T] cm3 molecule−1 s−1 for 3-bromopropene and 3-iodopropene, respectively. The atmospheric chemical lifetimes of these two compounds with O3 were also estimated from these values.
