Untersuchungen über die Kinetik und den Mechanismus der Oxydation von Isopropylbenzol in Gegenwart von Kobalt-und Mangansalzen der Pyridincarbonsäuren und von Kobaltacetylacetonat

摘要

The liquid phase oxidation of cumene in the presence of cobalt and manganese salts of α-, β- and γ-pyridinecarboxylic acids as well as of cobalt acetylacetonate has been kinetically studied. In view of determining the reaction mechanism during the initial period, a number of experiments were carried out in the presence of the most active catalysts. It was proved that all these catalysts take part in the initial stage of the radical chain process. The results are in accordance with the hypothesis for the formation of the intermediate complex with molecular oxyg
