This process has been studied by quantum chemical calculation, and a reaction potential energy surface has been developed. The rate constant of initial Cl atom fission has been calculated by canonical variational transition state theory as k = 1.45 × 1015 exp(−222 ± 9 kJ mol–1/RT) s–1 between 500 and 2000 K. A minimal kinetic model was developed to model the decomposition and major products. Oxidative decomposition was studied in nitrogen with O2 contents of 1, 6, 12, and 20 mol %. Increasing O2 to 6–8% increased the rate of decomposition of HCCP and decreased the yield of 8ClNP. Above 823 K, hexachlorobenzene (HCB) and CO became major products. The oxidative reaction has also been studied quantum chemically. At high O2 content (>∼10%), the rate of decomposition of HCCP declined as did yields of 8ClNP and HCB, but CO yields increased]]> Sat 24 Mar 2018 08:44:07 AEDT ]]> Gas phase thermal oxidation of endosulfan and formation of polychlorinated dibenzo-p-dioxins and dibenzofurans https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:26093 Sat 24 Mar 2018 07:39:55 AEDT ]]> Gas phase pyrolysis of endosulfan and formation of dioxin precursors of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/F) https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:32361 Mon 28 May 2018 11:46:59 AEST ]]> Mechanisms of thermal decomposition of cyclodiene pesticides, identification and possible mitigation of their toxic products https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:37366 Mon 19 Oct 2020 11:19:27 AEDT ]]>
