J. Barry et al., KINETIC DATA FOR THE REACTION OF HYDROXYL RADICALS WITH 1,1,1-TRICHLOROACETALDEHYDE AT 298+ - 2K/, Chemical physics letters, 221(5-6), 1994, pp. 353-358
The rate constant for the reaction of the hydroxyl radical with 1,1,1-
trichloroacetaldehyde has been determined at 298 +/- 2 K. Rate data we
re obtained at atmospheric pressure by a relative rate method. The rat
e 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 + CCl3CHO) = (1.1 +/- 0.2) x 10(-12) cm3 molecule-1 s-
1 at room temperature giving an atmospheric lifetime for CCl3CHO with
respect to reaction with OH radicals of 290 h.
