  • Process for preparing alkyl hydroperoxide compounds
    Patent number: 8722941
    Abstract: A method for making alkyl hydroperoxide compounds, specifically the preparation of cyclohexyl hydroperoxide is described. The preparation of cyclohexyl hydroperoxide by means of the oxidation of cyclohexane by oxygen in a multi-stage reactor or in reactors connected in series is also described. In these methods, the reactor surfaces in contact with the oxidation medium can be protected by a layer of heat-resistant PFA polymer.

  • PROCESS FOR THE MANUFACTURE OF ADIPIC ACID
    Publication number: 20110306789
    Abstract: A process for the manufacture of adipic acid carried out in devices made of material resistant to the corrosion of the synthesis medium is described. A process for the manufacture of adipic acid carried out in devices, some of which are made of a material resistant to corrosion by nitric acid, is also described. The corrosion-resistant material can be a “duplex” austenoferritic stainless steel of X2 CrNiN 23-4 (1.4362) type, according to the European nomenclature.
