Dq. Zhang et al., KINETICS OF THE REACTION OF HYDROXYL RADICALS WITH CH2BR2 AND ITS IMPLICATIONS IN THE ATMOSPHERE, Journal of atmospheric chemistry, 27(2), 1997, pp. 209-215
Rate constants for the reaction of hydroxyl radicals with dibromometha
ne have been measured by discharge flow-resonance fluorescence techniq
ue (DF-RF) over the temperature range 288-368 K. The derived Arrhenius
equation is k(1) = (1.51+/-0.37) x 10(-12) exp(-(720+/-60)/T) cm(3) m
olec.(-1) s(-1). The tropospheric lifetime of dibromomethane has been
estimated to be 0.29 years. An ozone depletion potential (ODP) value o
f 0.10 for dibromomethane has been obtained.
