Abstract:
1. A process for producing alkyl hydroperoxide, the process comprising oxidizing a saturated hydrocarbon in a liquid phase with an oxygen-containing gas, and conducting the oxidation in a plurality of successive steps, comprising supplying hydrocarbon at least to a first step at a temperature of from 100° C. to 250° C., further comprising cooling in, at least a last step of the reaction to maintain and control temperature at a level which is less than or equal to a temperature used in the first step, wherein each step of the reaction comprises a liquid phase and a gaseous phase and comprises forming a gaseous overhead extracting and evacuating the gaseous phase forming the overhead to be at least partially condensed, and recovering at least one condensate from the gaseous phase of one step and recycling the condensate directly into one of the oxidation steps, wherein a resulting concentration of oxidized products in the supplied reaction medium is at least equal to a concentration of oxidized products in the condensate or condensates to be recycled.
