Vl. Orkin et al., ATMOSPHERIC FATE OF CHLOROBROMOMETHANE - RATE-CONSTANT FOR THE REACTION WITH OH, UV SPECTRUM, AND WATER SOLUBILITY, The journal of physical chemistry. A, Molecules, spectroscopy, kinetics, environment, & general theory, 101(2), 1997, pp. 174-178
The rate constant for the reaction of CH2ClBr with OH was measured by
both flash photolysis resonance fluorescence and discharge flow electr
on paramagnetic resonance techniques over the temperature range 277-37
0 K. The Arrhenius expression 3.04(-0.6)(+0.8) x 10(-12) exp{-(978+/-7
2)/T} cm(3) molecule(-1) s(-1) was derived from a composite fit to bot
h data sets, Absorption cross-sections of CH2ClBr were measured from 1
87 to 290 nm at 295 K. The solubility of CH2ClBr in water was also est
imated to determine if such a process could be important in determinin
g the atmospheric lifetime of CH2ClBr. The atmospheric lifetime and oz
one depletion potential for CH2ClBr were estimated.
