Kinetics of the reactions of Cl atoms with CF3C(O)OCH3, CF3C(O)OCH2CH3, CF2HC(O)OCH3 in the temperature range of 287-313K and 1 atm
Rate coefficients of the reactions of Cl atoms with CF3C(O)OCH3 (k1), CF3C(O)OCH2CH3 (k2) and CF2HC(O)OCH3 (k3) have been measured for the first time in the temperature range of 287–313 K and 1 atm. Temperature dependencies of k are described by the Arrhenius expressions: k1 = (5 ± 2) × 10−12 exp[−(...

| Summary: | Rate coefficients of the reactions of Cl atoms with CF3C(O)OCH3 (k1), CF3C(O)OCH2CH3 (k2) and CF2HC(O)OCH3 (k3) have been measured for the first time in the temperature range of 287–313 K and 1 atm. Temperature dependencies of k are described by the Arrhenius expressions: k1 = (5 ± 2) × 10−12 exp[−(1216 ± 72)/T] (cm3 molecule−1 s−1), k2 = (539 ± 164) × 10−12 exp[−(1637 ± 94)/T] (cm3 molecule−1 s−1) and k3 = (20 ± 9) × 10−12 exp[−(1368 ± 82)/T] (cm3 molecule−1 s−1). The kinetic data are compared with previous theoretical calculations and a correlation between kCl and EHOMO of the halogenated VOC is presented. |
