摘要
Electron beam irradiation of trans- and cis-1,2-dichloroethylenes (cis-DCEs)-air mixtures was carried out in order to get quantitative information on chain oxidation. Decomposition of cis-DCE was initiated by OH, O(P-3) radicals, and thermal electrons and proceeded by Cl radical chain oxidation, whereas that of trans-DCE was initiated by not only the radicals and the electrons but also O-3. The chain lengths of trans-DCE by O-3 were estimated to be 6.2 +/- 0.2 independently of trans-DCE and O-3 concentrations. The decomposition mechanism was also clarified.
