Resumen:
product study is reported on the gas-phase reactions of
OH radicals and Cl atoms with methyl acrylate. The experiments
were performed in a 1080-L quartz-glass chamber in synthetic
air at 298 ( 2 K and 760 ( 10 Torr using long-path in situ
FTIR spectroscopy for the analysis of the reactants and products.
In the absence of NOx the major product observed in the OH
reaction is methyl glyoxylate, with formaldehyde as a coproduct.
For the reaction with Cl only formyl chloride (HC(O)Cl), CO,
and HCl could be positively identified as products, however,
the concentration-time behavior of these products show that
they are secondary products and originate from the further
oxidation of a major primary product. From this behavior and
a comparison with simulated spectra unidentified bands in the
residual product spectra are tentatively attributed to a
compound of structure CH2ClC(O)C(O)OCH3, i.e., formation of
methyl 3-chloro-2-oxopropanoate from the reaction of Cl with
methyl acry
