Rate constants of the Br-initiated gas-phase oxidation of a series of alcohols, furans and benzenes at 300±2 K

Using the relative kinetic technique, rate coefficients have been determined for the gas-phase reaction of Br atoms with a selection of organic compounds, including alcohols, furan derivatives and aromatic hydrocarbons, at 300±2 K in 1000 mbar of synthetic air. Rate coefficients have been obtained for the following compounds (in units of cm3 molecule−1 s−1): methanol (≤5×10−16); ethanol (9.2±1.8)×10−15; propan-1-ol (8.3±1.6)×10−15; propan-2-ol (4.6±0.9)×10−14; 2-methylpropan-2-ol (≤5×10−16); 3-bromobutan-2-ol (2.2±0.4)×10−13; furan (1.6±0.3)×10−15; 2-methylfuran (2.2±0.4)×10−13; 2,5-dimethylfuran (1.9±0.4)×10−12; furan-2-aldehyde (2.2±0.4)×10−13; 5-methylfurfural (4.0±0.8)×10−13; benzene (≤5×10−16); toluene (1.3±0.2)×10−14; o-xylene (8.9±1.8)×10−14; m-xylene (6.6±1.3)×10−14; p-xylene (9.0±1.8)×10−14, and 1,2,3-trimethylbenzene (4.8±1.0)×10−13. Apart from methanol, this study represents the first determination of the rate coefficients for these compounds
