Kinetics of the gas-phase reaction between ozone and three unsaturated oxygenated compounds: Ethyl 3,3-dimethyl acrylate, 2-methyl-2-pentenal and 6-methyl-5-hepten-2-one at atmospheric pressure

摘要

Rate coefficients for the gas-phase reactions of O-3 molecules with three unsaturated oxygenated compounds have been determined using the relative kinetic technique in an environmental chamber with FTIR detection of the reactants at (298 +/- 2) K in 760 Torr total pressure of synthetic air. The following rate coefficients (in units of 10(-17) cm(3) molecule(-1) s(-1)) were determined: ethyl 3,3-dimethyl acrylate (0.82 +/- 0.19), 2-methyl-2-pentenal (0.71 +/- 0.16) and 6-methyl-5-hepten-2-one (26 +/- 7).
