Kinetic data for the reaction of hydroxyl radicals with 1,1,1-trichloroacetaldehyde at 298 ± 2 K

The rate constant for the reaction of the hydroxyl radical with 1,1,1-trichloroacetaldehyde has been determined at 298 ± 2 K. Rate data were obtained at atmospheric pressure by a relative rate method. The rate constant was also measured at lower pressures (1–3.4 Torr) using the discharge flow techni...

Description
Summary:The rate constant for the reaction of the hydroxyl radical with 1,1,1-trichloroacetaldehyde has been determined at 298 ± 2 K. Rate data were obtained at atmospheric pressure by a relative rate method. The rate constant was also measured at lower pressures (1–3.4 Torr) using the discharge flow technique with OH radical detection both by resonance fluorescence and electron paramagnetic resonance. The results provide a value of k(OH + CCl 3CHO) = (1.1 ± 0.2) × 10 −12 cm 3 molecule −1 s −1 at room temperature giving an atmospheric lifetime for CCl 3CHO with respect to reaction with OH radicals of 290 h.
