英文摘要	The rate constants for the reaction of OH radicals with six halogenated propenes—(Z)-CF3CCl = CHCl (k1), CHF2CF=CF2 (k2), (E)-CF3CH=CHF (k3), (Z)-CF3CH=CHF (k4), CH3CF=CH2 (k5), and CH2FCH=CH2 (k6)—were measured over 250–430 K using the absolute rate method. The Arrhenius expressions for the rate constants were determined as k1 = (9.30 ± 0.54) × 10−13 exp [−(180 ± 20)/T], k2 = (1.43 ± 0.04) × 10−12 exp [(490 ± 10)/T], k3 = (4.86 ± 0.13) × 10−13 (T/298)0.727 exp [(110 ± 10)/T], k4 = (4.55 ± 0.12) × 10−13 (T/298)0.367 exp [(350 ± 10)/T], k5 = (3.22 ± 0.20) × 10−12 exp [(490 ± 20)/T], and k6 = (2.87 ± 0.19) × 10−12 exp [(440 ± 20)/T] cm3 molecule−1 s−1. Infrared absorption spectra of the halogenated propenes were measured at room temperature. The atmospheric lifetimes, global warming potentials of the halogenated propenes, and ozone depletion potential of (Z)-CF3CCl = CHCl were estimated. The correlation between the reactivity and structure of 44 halogenated alkenes, including the six halogenated propenes, was investigated. © 2021 Elsevier Ltd
