英文摘要: Rate coefficients for the gas phase reactions of OH radicals with 2,2,2-trifluoroethylmethacrylate (k1) 1,1,1,3,3,3-hexafluoroisopropylacrylate (k2), 1,1,1,3,3,3-hexafluoroisopropylmethacrylate (k3), and 2,2,2-trifluoroethylacrylate (k4) were determinated to be k1=(2.54±0.12)×10-11, k2=(1.41±0.11)×10-11, k3=(1.65±0.14)×10-11 and k4=(1.25±0.13)×10-11cm3molecule-1s-1, respectively. Kinetic experiments were performed at room temperature and atmospheric pressure using the relative-rate technique with GC-FID analysis. This study is the first kinetic for these reactions of OH radicals under atmospheric pressure. Additionally, the rate constants obtained are compared with other halogenated and non halogenated acrylates and methacrylates to develop structure/reactivity relationships in terms of the presence of fluorine and ester groups and the hydrocarbon chain length. The atmospheric implications of the reactions were assessed by the estimation of the tropospheric lifetimes of the title reactions. © 2014 Elsevier Ltd. Citation statistics:
