Kinetic study of gas phase reactions of pinonaldehyde and structurally related compounds
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).
