Graphical Abstract
Der geschwindigkeitsbestimmende Schritt der Ethylen-Oxychlorierung am CuCl2/γ-Al2O3-Katalysator ließ sich in einer zeitaufgelösten In-situ-XANES-Studie identifizieren. Nach diesen Daten (siehe Bild; E=Photonenenergie) und der ebenfalls ermittelten Katalysatoraktivität ist es die Oxidation von CuCl. Das den industriellen Katalysatoren als Dotierung zugesetzte Kaliumchlorid verringert die Geschwindigkeit der Reduktion, die beim KCl/CuCl2/γ-Al2O3-Katalysator zum geschwindigkeitsbestimmenden Schritt wird.

- 14 XANES spectroscopy is one of the most informative techniques for determining oxidation states and local symmetries of transition metal ions [see for example A. Bianconi in X-Ray Absorption ( ), Wiley, New York, 1988, p. 573]. This is particularly true when model compounds with well-defined oxidation and coordination states are available for comparison. In this regard, the reader should refer to refs. [7, 8]. It has been shown that the spectra of the as-activated catalyst and of the catalyst after interaction with O2 [that is, at the end of the cycle described in Equations (2)–(4)] are very close to that of the CuCl2 model compound. In addition, the XANES spectra of the catalyst after interaction with C2H4 under static conditions are in fair agreement with that of CuCl, except for a less pronounced 1s→4p transition. This difference has been explained in terms of the high dispersion of the CuCl particles on the reduced catalyst, showing 50 % of surface CuI as determined in a combined IR/CO chemisorption study.[7]
- 15 In a parallel experiment, in which only HCl was dosed to the oxychloride phase, it was demonstrated that the chlorination of the oxychloride occurs already at 373 K. This implies that reaction (4) is immediate at the temperature of interest, thus it is not responsible for the presence of CuII.
- 16 The ability of potassium and copper to form the phase KCuCl3 is well known, see for example: N. N. Greenwood, A. Earnshaw, Chemistry of the Elements, Pergamon, Oxford, 1986, p. 1385.
