Notizen: Validation of the mechanism of tetrachloroethene photochlorination at low C2Cl4 concentrations was investigated. The reaction was examined in carbon tetrachloride solution. For initial tetrachloroethene concentrations below 2 mol I-1, the solvent participates in a free-radical chain photochlorination. The presence of CCl4 disturbs the course of this particular chain reaction and influences the duration of the induction period.

Notizen: Photochlorination of tetrachloroethylene has been studied in a homogeneous liquid system. Kinetic parameters such as reaction orders for chlorine, tetracholoroethylene and light intensity, preexponential factor, and activation energy were evaluated from experimental data. The following kinetic equation was obtained by parameter estimation following the Marquardt procedure: \documentclass{article}\pagestyle{empty}\begin{document}$$ r = \left( {4.02 \pm 0.46} \right)10^{ - 5} \exp \left( { - \frac{{54,700 \pm 200}}{{RT}}} \right)I^{0.489 \pm 0.003} C_{Cl_2 }^{0.889 \pm 0.160} C_{C_2 Cl_4 }^{1.040 \pm 0.042} $$\end{document}
