METHOD FOR OXIDIZING HYDROCARBONS WITH OXYGEN

摘要

The present invention relates to a method for oxidizing saturated hydrocarbons with oxygen, preferably saturated cyclic hydrocarbons such as cyclohexane, in order to produce alkyl hydroperoxide. The invention relates specifically to a method for oxidizing saturated hydrocarbons with oxygen, the oxidation being carried out in a plurality of consecutive steps in order to control the rate of the hydrocarbon oxidation reaction and to obtain a high degree of alkyl hydroperoxide selectivity. The method of the invention relates to the method for condensing the oxidation gases recovered in each oxidation reactor and the recycling thereof in the oxidation reactors. According to the recycling method of the invention, the selectivity of the ketone and alcohol reaction is improved, as well as the economy of the method, by a decrease in "cold" hydrocarbons supplied to certain reactors in order to control the temperature.
