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.
