The present invention relates to a process for the preparation of hexamethylenediamine by hydrogenation of adiponitrile in the presence of a Raney nickel catalyst, wherein a Raney nickel catalyst modified by treatment with carbon monoxide or carbon dioxide in a liquid medium is used.

Process for the preparation of hexamethylenediamine by hydrogenation of adiponitrile with reduced formation of diaminocyclohexane

The present invention concerns a method of oxidizing a cycloalkane to form a product mixture containing a corresponding alcohol and ketone, said method comprising contacting the cycloalkane with a hydroperoxide compound in the presence of a heterogenous catalyst comprising gold.

Method for oxidation of cycloalkanes

The present invention concerns a method of oxidizing a cycloalkane to form a product mixture containing a corresponding alcohol and ketone, said method comprising contacting a cycloalkane with a hydroperoxide compound in the presence of a catalytic effective amount of a cerium oxide based catalyst.

Cycloalkane oxidation catalysts and method to produce alcohols and ketones

Process for the manufacture of at least one alcohol and/or at least one ketone, which comprises a step during which at least one organic peroxide compound is put into contact with at least one catalyst responding to formula (I) CrNOFormula (I) in which x is a number varying from 0.10 to 1.00 and y is a number varying from 0.00 to 1.50, in order to produce the at least one alcohol and/or at least one ketone.

Process for the manufacture of alcohol and/or ketone

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 process for preparing dicarboxylic acids is described. More particularly a process is described for preparing adipic acid (1,6-hexanedioic acid), by the action of nitric acid, starting from cyclic ketones or alcohols which are the corresponding compounds from the standpoint of the number of carbon atoms, in the presence of one or more oxides of nitrogen at a molar concentration in the reaction mixture of greater than 2.5 mmol per kg of reaction mixture.
