| Abstract
| - Kinetic studies on the gas-phase reactions of OH and NO3 radicals and ozone with ethyl vinyl ether (EVE),propyl vinyl ether (PVE) and butyl vinyl ether (BVE) have been performed in a 405 L borosilicate glasschamber at 298 ± 3 K in synthetic air using in situ FTIR spectroscopy to monitor the reactants. Using arelative kinetic method rate coefficients (in units of cm3 molecule-1 s-1) of (7.79 ± 1.71) × 10-11, (9.73 ±1.94) × 10-11 and (1.13 ± 0.31) × 10-10 have been obtained for the reaction of OH with EVE, PVE andBVE, respectively, (1.40 ± 0.35) × 10-12, (1.85 ± 0.53) × 10-12 and (2.10 ± 0.54) × 10-12 for the reactionof NO3 with EVE, PVE and BVE, respectively, and (2.06 ± 0.42) × 10-16, (2.34 ± 0.48) × 10-16 and (2.59± 0.52) × 10-16 for the ozonolysis of EVE, PVE and BVE, respectively. Tropospheric lifetimes of EVE,PVE and BVE with respect to the reactions with reactive tropospheric species (OH, NO3 and O3) have beenestimated for typical OH and NO3 radical and ozone concentrations.
