Abstract

Kinetics of the OH-initiated reactions of acetic acid and its deuterated isomers have been investigated performing simulation chamber experiments at T = 300 ± 2 K. The following rate constant values have been obtained (± 1σ, in cm3 molecule-1 s -1): k 1(CH3C(O)OH + OH) = (6.3 ± 0.9) × 10-13, k 2(CH3C(O)OD + OH) = (1.5 ± 0.3) × 10-13, k 3(CD3C(O)OH + OH) = (6.3 ± 0.9) × 10-13, and k 4(CD3C(O)OD + OH) = (0.90 ± 0.1) × 10-13. This study presents the first data on k 2(CH3C(O)OD + OH). Glyoxylic acid has been detected among the products confirming the fate of the CH2C(O)OH radical as suggested by recent theoretical studies.
