Process for decomposing a mixture containing cycloalkylhydroperoxide, which mixture includes an organic phase and an aqueous phase wherein, during the decomposition, at least one compound is present which meets the following parameters:

Process for decomposing cycloalkylhydroperoxide

The invention relates to a process for decomposing a mixture containing cycloalkyl hydroperoxide with an aqueous phase containing alkali metal hydroxide where, besides the alkali metal hydroxide, there is also at least 10 wt. % of the aqueous phase of one or more alkali metal salts. The alkali metal salts are preferably alkali metal carbonates, or alkali metal salts of mono- and poly-carboxylic acids, with the carboxylic acid moiety containing 1-24 carbon atoms.

Process for decomposing cycloalkyl hydroperoxide

An improved process for preparing alkanones and alkanols by oxidizing an alkane and/or alkene having from 3 to 30 carbon atoms to form an oxidation mixture containing alkylhydroperoxide. A basic, aqueous solution is added to the oxidation mixture so that a separate basic water phase with a pH higher than 8.5 is formed. The alkylhydroperoxide is then decomposed in the presence of a heterogeneous catalyst which contains a metal compound immobilized on a carrier material. The metal of the catalyst is selected from the group consisting of Mn, Fe, Co, Ni, and Cu. The carrier material is stable in the presence of the separate basic water phase.

Process for preparing alkanones and alkanols

The invention relates to a process for the preparation of a phenol-formaldehyde resin by causing phenol and formaldehyde to condense under the influence of a basic catalyst, the catalyst being an aqueous solution containing alkali metal ions, carbonate ions, ions of carboxylic acids and one or more ions chosen from the group comprising transition metal ions and borates.

Process for the preparation of a phenol-formaldehyde resin

The invention relates to a process for preparing an alkanone and/or alkanol by oxidizing an alkane with 3-30 C-atoms, using oxygen, to form an alkyl hydroperoxide, followed by a decomposition of the resulting alkyl hydroperoxide in the presence of a metal compound immobilized on a carrier, which carrier carries aliphatic or aromatic amine groups or sulphide groups. The process is preferably applied to cycloalkanes.

Process for preparing an alkanone and/or alkanol

The invention relates to a process for preparing a cycloalkanone and/or cycloalkanol by oxidation of a cycloalkane using oxygen to form a hydroperoxide, followed by a decomposition of the hydroperoxide, in the presence of an organic metal complex, the decomposition being carried out in the presence of a phthalocyanine or porphyrin metal complex immobilized on a carrier material.
