ate coefficients of the reactions of Cl atoms with CF3C(O)OCH3(k1), CF3C(O)OCH2CH3(k2) andCF2HC(O)OCH3(k3) have been measured for the first time in the temperature range of 287?313 K and1 atm.Temperature dependencies of k are described by the Arrhenius expressions: k1= (5 ± 2) × 10−12exp[−(1216 ± 72)/T] (cm3molecule−1s−1), k2= (539 ± 164) × 10−12exp[−(1637 ± 94)/T] (cm3molecule−1s−1) and k3= (20 ± 9) × 10−12exp[−(1368 ± 82)/T] (cm3molecule−1s−1). The kinetic data are comparedwith previous theoretical calculations and a correlation between kCland EHOMOof the halogenated VOCis presented.
