Abstract

In this paper rate constants for the reactions of OH, NO(3) and O(3) with pinonaldehyde and the structurally related compounds 3-methylbutanal, 3-methylbutan-2-one, cyclobutyl-methylketone, and 2,2,3-trimethyl-cyclobutyl-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: k(OH) = (9.3 +/- 1.5) E-11 cm(3)molecule(-1)s(-1) k(NO3) = (5.4 +/- 1.8) E-14 cm(3)molecule(-1)s(-1), k(03) = (8.9 +/- 1.4) E-20 cm(3) molecule(-1)s(-1). The results obtained indicate a chemical lifetime of pinonaldehyde in the troposphere of about two hours under typical daytime conditions, [OH] = 1.6E6 molecule cm(-3).
