WebFeb 17, 2009 · We have proposed the reaction (1) Cl + C 6 H 5 Cl → products may lead to chlorophenyl radicals which could react with chlorobenzene in part via H-atom displacement [7]. These steps can form part of a combustion chain reaction where H atoms then consume chlorobenzene by abstraction of Cl. michael napier trucking expert

WebH-abstraction to form HCl and chlorophenyl radicals is a plausible pathway at higher temperatures because for the analogous Cl + benzene reaction the endothermicity is 40.5 ± 2.5 kJ mol-1. at 298 K [10]. We investigate this possibility further using density functional theory, with the MPWB1K functional and the MG3 basis set [13].
