Rate coefficients for the reactions of chlorine atoms with methanol and acetaldehyde

Abstract: Rate coefficients have been measured for the reactions of Cl atoms with methanol (k 1 ) and acetaldehyde (k 2 ) using both absolute (laser photolysis with resonance fluorescence) and relative rate methods at 295 Ϯ 2 K. The measured rate coefficients were (units of 10Based on a critical evaluation of the literature data, the following rate coefficients are recommended: k 1 ϭ (5.4 Ϯ 0.9) ϫ 10 Ϫ11 and k 2 ϭ (7.8 Ϯ 1.3) ϫ 10 Ϫ11 cm 3 molecule Ϫ1 s Ϫ1 (95% confidence limits). The results significantly improve the c… Show more

“…A goal of our study was to improve the general understanding of the reactivity of the acetyl radical. The reactions of the acetyl radical with some potentially atmospherically important molecules that have been investigated to date include reactions with O 2 [6,7,13,20,22], NO 2 [5], NO 3 [8], and NO [13]. Clearly, the most important reaction of the acetyl radical in the atmosphere is its reaction with O 2 .…”

“…Sensitivity analysis identified the remaining critical parameters as those controlling the concentration of parent radicals, [CH 3 C(O)O 2 ], and the rate coefficient for conversion to OH, k 1 . Uncertainties in: laser fluence (±20%); [Cl 2 ] (±10%); relative [CH 3 CHO] to [CH 3 OH] (±10%); rate coefficients k 15 and k 11 (relative rate measured both relative to C 2 H 6 and C 2 H 4 to about ±5%; Tyndall et al, 1999) were therefore combined to give an overall estimate of ±25% in [CH 3 C(O)O 2 ]. This value was combined with an effective uncertainty in k 1 (±15%, see Sect.…”
