| Zusammenfassung |
| The reactions of Cl atoms with a series of unsaturated aldehydes have been
investigated for the first time using a relative method. In order to obtain
additional information for a qualitative structure versus reactivity
discussion, we have also determined the rate coefficients for the reactions
of atomic chlorine with their respective saturated aldehydes. These relative
measurements were performed at room temperature and atmospheric pressure of
air and N2, by using ethane, propene and 1-butene as reference
compounds. The weighted average relative rate constants obtained, kCl±2σ (in units of cm3 molecule−1 s−1) were:
trans-2-pentenal (1.31±0.19)×10−10; trans-2-hexenal
(1.92±0.22)×10−10; trans-2-heptenal (2.40±0.29)×10−10;
n-pentanal (2.56±0.27)×10−10;
n-hexanal (2.88±0.37)×10−10; n-heptanal (3.00±0.34)×10−10.
Finally, results and atmospheric implications are discussed and compared
with the reactivity with OH and NO3 radicals. |
