|Abstract:||Rate constants for the reactions of OH, No3 and O3 with pinonaldehyde and the structurally related compounds 3-methylbutanal, 3-methylbutan-2-one, cyclobutyl-methylketone, and 2,2,3-trimethylcyclobutyl-1-ethanone have been measured at 300+- 5 K using on-line Fourier transform infrared spectroscopy. The rate constants obtained for the reactions with pinonaldehyde were: kOH=(9.3+-1.5)x10-11 cm3 molecule-1s-1, kNO3= (5.4+-1.8)x10-14 cm3 molecule-1s-1, kO3=(8.9+-1.4)x10-20 cm3 molecule-1s-1. The results obtained indicate a chemical lifetime of pinonaldehyde in the troposphere of about two hours under typical daytime conditions, [OH]=1.6x10 6 molecule cm-3.|
