Resumen
The kinetics of the reactions of Cl atoms with three unsaturated carbonyl compounds at 298 K and atmospheric pressure were investigated for the first time using the GC-FID technique. Rate coefficients (in cm3 molecule-1 s-1) of k1(Cl + CH2{double bond, long}CHC(O)CH2CH3) = (2.91 ± 1.10) × 10-10, k2(Cl + CH2{double bond, long}CHOC(O)CH2CH3) = (2.06 ± 0.36) × 10-10 and k3(Cl + CH2{double bond, long}CHC(O)OCH2CH3) = (2.53 ± 0.46) × 10-10 were obtained using the relative rate method with different references. Structure activity relationships (SARs) were developed for the reactions of Cl with a wide range of unsaturated compounds. On the basis of our kinetic measurements, tropospheric lifetimes of the studied unsaturated compounds are estimated.
