    Notizen: The gas-phase photochlorination (λ = 436 nm) of the 1,1,1,2-C2H2Cl4 has been studied in the absence and the presence of oxygen at temperatures between 360 and 420°K. Activation energies have been estimated for the following reaction steps: \documentclass{article}\pagestyle{empty}\begin{document}$$\begin{array}{*{20}c} {{\rm CCl}_3 {\rm CHCl}^{\rm .} + {\rm Cl}_2 \to {\rm CCl}_3 {\rm CHCl}_{\rm 2} + {\rm Cl}^{\rm .}} & {E_3 = (4.6 \pm 0.4){\rm kcal/mole}} \\ \end{array}$$\end{document} \documentclass{article}\pagestyle{empty}\begin{document}$$\begin{array}{*{20}c} {{\rm CCl}_3 {\rm CHCl}^{\rm .} \to {\rm CCl}_2 {\rm CHCl} + {\rm Cl}^{\rm .}} & {E_4 = (20.6 \pm 1.4){\rm kcal/mole}} \\ \end{array}$$\end{document} \documentclass{article}\pagestyle{empty}\begin{document}$$\begin{array}{*{20}c} {{\rm CCl}_3 {\rm CHClO}_{\rm 2} {\rm CHClCCl}_3 \to 2{\rm CCl}_3 {\rm CHClO}^{\rm .}} & {E_{15} = (33.5 \pm 3.0){\rm kcal/mole}} \\ \end{array}$$\end{document}The dissociation energy D(CCl3CHCl—O2) ± (24.8 ± 1.5) kcal/mole has also been estimated from the difference in activation energy of the direct and reverse reactions The mechanism is discussed and the rate parameters are compared to those obtained for a series of other chlorinated ethanes.

    Notizen: The competitive photochlorination and chlorine photosensitized dehydrochlorination of 1,1,1,2-C2H2Cl4 have been studied over the temperature range of 349.4-404.5 K after less than 1% conversion. The results are discussed and a value of \documentclass{article}\pagestyle{empty}\begin{document}$$ \log k_{4A} (\sec ^{ - 1}) = (11.6\pm 0.6) - (16,400\pm 1000)/4.58T $$\end{document} is proposed for the reaction \documentclass{article}\pagestyle{empty}\begin{document}$$ {\rm CCl}_{\rm 3} {\rm CHCl}\mathop \to \limits^{(4{\rm A)}} {\rm CCl}_{\rm 2} {\rm CHCl + Cl} $$\end{document} This result, combined with existing thermochemical data, indicates that there is no evidence of an activation energy for the addition of a Cl atom on the most chlorinated carbon in trichloroethylene: in that case the selectivity of the addition of Cl on the less chlorinated carbon should not depend on temperature.

    Notizen: Long-chain chlorine-photosensitized oxidation has been observed in the gas phase at about 355°K for 1,1,2,2- and 1,1,1,2-C2H2Cl4, C2HCl5, and C2Cl4 but not for C2H6, 1,2-C2H4Cl2, 1,1,1-C2H3Cl3, C2H4, and 1,2-C2H2Cl2. This is shown to depend on the exothermicity of the dissociation of the chloroethoxy radicals which must be involved in each reaction system.

    Notizen: The oxidation of nitrogen monoxide has been studied extensively between 226 and 758 K at pressures of NO and O2 ranging from about 0.2 to 30 torr. It has been shown that (i) the reaction is properly first order against oxygen and second order against nitrogen monoxide, as well under initial conditions as during the course of the reaction; (ii) the termolecular rate constant, k, first decreases with increasing temperature and reaches a minimum value at 600 K; (iii) the transition state theory is unable to describe this behavior correctly, (iv) under the present experimental conditions k can be represented either by \documentclass{article}\pagestyle{empty}\begin{document}$$ \log _{10} k({\rm l}^{\rm 2} {\rm mol}^{ - 2} {\rm s}^{ - 1}) = - (5.18 \pm 1.00) + (2.70 \pm 0.25){\rm log}_{{\rm 10}} T + (700 \pm 50)/T $$\end{document} or by \documentclass{article}\pagestyle{empty}\begin{document}$$ k({\rm l}^{\rm 2} {\rm mol}^{ - 2} {\rm s}^{ - 1}) = (350 \pm 100)10^{(390 \pm 50)/T} + (8000 \pm 2000)10^{ - (440 \pm 50)/T} $$\end{document} The latter equation is compatabile with a multiple-step mechanism.

    Notizen: Different possible mechanisms for the gas phase reaction of formation of bromine chloride from bromine and chlorine are discussed. The rate of the reaction has been deduced from photometric measurements in conventional static reactors of surface-to-volume ratio ranging between 0.6 and 3 cm-1, at temperatures between 51 and 113°C. Experimental data show that (1) the observed reaction is predominantly heterogeneous, and (2) the homogeneous reaction must proceed by an atomic chain mechanism initiated by Br atoms.
