Rate constants for the gas-phase reactions of O3 with the carbonyls acrolein, crotonaldehyde, methacrolein, methylvinylketone, 3-penten-2-one, 2-cyclohexen-1-one, acetaldehyde, and methylglyoxal have been determined at 296 ± 2 K. The rate constants ranged from <6 × 10−21 cm3 molecule−1 s−1 for acetaldehyde to 2.13 × 10−17 cm3 molecule−1 s−1 for 3-penten-2-one. The substituent effects of CHO and CH3CO groups on the rate constants are assessed and discussed, as are implications for the atmospheric chemistry of the natural hydrocarbon isoprene.
