Resumen:
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 dependences of k are described by the Arrhenius expressions: k1= (5 +/- 2) x 10-12 exp[-(1216 +/- 72)/T] (cm3 molecule-1 s-1), k2= (539 +/- 164) x 10-12 exp[-(1637 +/- 94)/T] (cm3 molecule-1 s-1) and k3= (20 +/- 9) x 10-12 exp[-(1368 +/- 82)/T] (cm3 molecule-1 s-1). Kinetic data obtained are compared theoretical calculations and a correlation between kCl and EHOMO of the halogenated VOC is presented.
