A method for oxidizing hydrocarbons, in particular saturated hydrocarbons, for producing peroxides, alcohols, ketones, aldehydes and/or diacids is described. Also described, is a method for oxidizing a cycloaliphatic saturated hydrocarbon using molecular oxygen for producing ketones/alcohols, and more precisely for oxidizing cyclohexane into cyclohexanol and cyclohexanone using molecular oxygen.

Process for the oxidation of hydrocarbons

A process for preparing a deperoxidation catalyst comprising chromium as the main catalytic element is described. Also described, is a process for preparing an organic solution of a chromic acid ester. The solution can be used as a catalyst in a deperoxidation of an alkyl peroxide in a process for manufacturing cyclohexanol/cyclohexanone by oxidation of cyclohexane.

Method for preparing a deperoxidation catalyst

A method for preparing an alkyl hydroperoxide obtained by the oxidation of a saturated hydrocarbon using oxygen, preferably of a saturated cyclic hydrocarbon, is described. Also described, is a method for preparing cyclohexyl hydroperoxide by oxidizing cyclohexane with molecular oxygen or a gas containing molecular oxygen preferably in the absence of a catalyst.

Process for the production of an alkyl hydroperoxide

A process for the recovery of compounds present in a mixture containing residues of heavy products is provided. The process includes conducting a reaction and distillation to obtain the compounds and residues and macerating the residues before they can set to mass. The residues can then be destroyed. The process is particularly suitable for the treatment of the residues obtained in the preparation of phenol from cumene.
