Abstract
A process for producing a hydroperoxide in highly concentrated form by oxidation of its corresponding liquid hydrocarbon with oxygen or an oxygen-containing gas while simultaneously subjecting the liquid reaction mixture to a carrier gas distillation to remove unreacted hydrocarbon with the carrier gas while withdrawing a portion of the liquid reaction mixture which is enriched in the hydroperoxide.

In a continuous process for the production of an organic mono- or di-hydroperoxide by oxidation of its corresponding hydrocarbon in the liquid state with oxygen or an oxygen-containing gas at an elevated temperature of approximately 80.degree.-175.degree.C with reference to normal pressure, the improvement which comprises:
- contacting the liquid hydrocarbon with the oxygen in a reaction zone maintained at the reaction temperature to form a reaction mixture containing the hydroperoxide product together with unreacted hydrocarbon;
- simultaneously subjecting the reaction mixture to a rectifying carrier gas distillation in the same zone as the reaction zone for removal of an overhead fraction consisting predominately of unreacted hydrocarbon together with the carrier gas;
- and
- withdrawing a residual bottoms fraction from the reaction zone to separate that portion of the reaction mixture in which the hydroperoxide product is more highly concentrated.
