Resumen:
Rate coefficients for the gas-phase reactions of Cl atoms with (CH3)2C=CHC(O)H and
CH3CH=CHC(O)OCH3 were determined to be (in units of 10-10 cm3 molecule-1 s-1 ): 2.48 ± 0.71 and
2.04 ± 0.56, respectively. The experiments were performed by the relative technique in an environmental
chamber with FTIR detection of the reactants at 298 K and 760 Torr. Structure activity relationships were
developed for the reactions of Cl with a series of unsaturated esters and aldehydes. In addition, a comparison
between the experimentally determined kCl with kCl predicted from k vs. HOMO correlations is presented.
The atmospheric persistence of these compounds was calculated taking into account the
measured rate coefficients.
