“…The finding that the dominant decomposition route for the alkoxy radical is Cl, elimination is also consistent with the conclusions of Atkinson (1989a) whose results are based on thermochemical calculations involving differences in heats of reaction of the decomposition routes. The proposed mechanism is also consistent with the results of Sanhueza et al (1976) who investigated the decomposition routes for analogous halogenated alkoxy radicals.…”

“…al. [22] correlated the preferred decomposition modes of the chloroethoxy radicals with the difference in the bond energies between the C-C1 bond of the oxygen-bearing carbon atom and the C-C bond. When the bond energy difference [D(C-Cl)-D(C-C)I is 2 6 kcal mol-', almost all of the chloroethoxy radical reacts through C-C bond scission; Table I11 for the respective chloroethoxy radicals.…”

“…The cause for the very low observed yield of HC(0)Cl in the presence of added ethane is not known. It is interesting to note, however, that Sanhueza et al [22] invoked reaction channels leading to a n energetic HC(0)Cl molecule, which always decomposes to CO and HC1, in explaining the results of the C1-atom sensitized oxidation of the chloroethenes. [The generally low yields of HC(0)Cl from cis-and trans-l,2-dichloroethene may also be related to this cause].…”

The kinetics and products of the homogeneous gas-phase reactions of the OH radical with the chloroethenes were investigated at 298 ? 2 K and atmospheric pressure. Using a relative rate technique and ethane as a scavenger for the chlorine atoms produced in these OH radical reactions, rate constants (in units of lo-'' cm3 molecule.'s-'j of 8.11 ? 0.24, 2.38 ? 0.14, and 1.80 ? 0.03 were obtained for 1,l-dichloroethene, cis-l,2-dichloroethene and trans-l,2-dichloroethene, respectively. Under these conditions, the major products observed by long pathlength FT-IR absorption spectroscopy were HCHO and HC(OjC1 from vinyl chloride; HC(OjC1 from cis-and trans-1,2-dichloroethene; HCHO and COCI, from 1,l-dichloroethene; HC(OiC1 and COCI, from trichloroethene; and COC1, from tetrachloroethene. In the absence of a C1 atom scavenger, significant yields of the chloroacetyl chlorides, CH,Cl,-,C(O)Cl, were observed from 1,l-dichloro-, trichloro-and tetrachloroethene, indicating that these products resulted from reactions involving chlorine atoms. The yields of all of these products are reported and the mechanisms of these gas-phase reactions discussed. In addition, OH radical reaction rate constants were redetermined, in the presence of a Cl atom scavenger, for cis-and trans-1,3-dichloropropene and 3-chloro-2-chloromethyl-1-propene, being (in units of 10 cm' molecule-' s-') 8.45 f 0.41, 14.4 t 0.8, and 33.5 -t 3.0. respectively.
