Heterogenized transition metal halides in the preparation of highly dispersed metal and metal complex catalysts. vi. the formation of the active surface of cupric chloride heterogenized on silica gel and its catalytic activity in the oxidation of cumene
X-ray photoelectron and ESR spectroscopy was used to study the distribution and state of the active component on the support surface after the heterogenization of cupric chloride on lithium-modified silica gel. The chemisorption of CuC1/sub 2/ is mainly insular in nature. The catalytic activity of the catalysts obtained was studied in the liquid-phase oxidation of cumene to give cumyl hydroperoxide. The nature of the dependence of the specific catalytic activity on the surface concentration of the supported halide may be explained assuming insular nature for the chemisorption of CuC1/sub 2/. A comparison was carried out for the catalytic activity, selectivity and stability of the catalyst obtained with its impregnation analog and a number of significant advantages of the former were found relative to all these parameters.
