Rate constants for the gas phase reaction of ozone with n-butyl acrylate and ethyl methacrylate

Rate constants for the reaction of ozone with n-butyl acrylate (BUAC) and ethyl methacrylate (ETMEAC) have been investigated for the first time. At 293 ± 1 K and atmospheric pressure, the measured values were (2.40 ± 0.29) × 10−18 cm3 molecule−1 s−1 for BUAC and (7.68 ± 0.88) × 10−18 cm3 molecule−1 s−1 for ETMEAC. The atmospheric lifetimes have also been estimated, which indicate that only in the polluted areas could reaction with ozone be one of the important sinks for these unsaturated esters.
