    摘要: The present invention relates to a process for decomposing organic hydroperoxides in the presence of a catalyst. It provides a process for decomposing organic hydroperoxides in the presence of a catalyst into a mixture of alcohols and ketones, in which the catalyst comprises at least one ruthenium-based catalytically active metallic element incorporated into a solid support chosen from the group comprising metal oxides and carbon blacks, such as the carbon blacks obtained by the pyrolysis of organic compounds. The process of the invention is especially useful in the decomposition of important chemical intermediates such as cyclohexyl hydroperoxide.

    摘要: The present invention relates to a process for the oxidation of hydrocarbons, in particular of branched or unbranched saturated aliphatic hydrocarbons, of cycloaliphatic or alkylaromatic hydrocarbons or of alcohols and/or ketones, to acid or polyacid compounds.It relates more particularly to the oxidation, by an oxidizing agent comprising molecular oxygen, of cyclohexane and/or of cyclohexanol and/or cyclohexanone to adipic acid, in the presence of an aromatic organic acid and a manganese-based catalyst. The yield and selectivity for adipic acid are of a high level with respect to those obtained with other solvents and catalysts.

    摘要: The present invention relates to a process for oxidizing hydrocarbons, in particular branched or unbranched saturated aliphatic hydrocarbons, cycloaliphatic or alkylaromatic hydrocarbons to acidic or polyacidic compounds.The invention relates more particularly to the oxidation, with an oxidizing agent containing molecular oxygen, of cyclohexane to adipic acid, in the presence of organic acid of lipophilic nature and in the absence of adipic acid. The separation and recycling of the unoxidized cyclohexane, the oxidation intermediates and the catalysts are easier than in the presence of acetic acid.
