Rate constants for the reactions of OH, NO3, and O-3 with pinonaldehyd
e and the structurally related compounds 3-methylbutanal, 3-methylbuta
n-2-one, cyclobutyl-methylketone, and 2,2,3-trimethyl-cyclobutyl-1-eth
anone have been measured at 300 +/- 5 K using on-line Fourier transfor
m infrared spectroscopy. The rate constants obtained for the reactions
with pinonaldehyde were: k(OH)=(9.1 +/- 1.8) x 10(-11) cm(3) molecule
(-1) s(-1), k(NO3) = (5.4 +/- 1.8) x 10(-14) cm(3) molecule(-1) s(-1),
and k(O3) = (8.9 +/- 1.4) x 10(-20) cm(3) molecule(-1) s(-1). The res
ults obtained indicate a chemical lifetime of pinonaldehyde in the tro
posphere of about two hours under typical daytime conditions, [OH] = 1
.6 x 10(6) molecule cm(-3). (C) 1997 John Wiley and Sons, Inc.
