Title:

HIGH SHEAR OXIDATION OF CYCLOHEXANE

Document Type and Number:

WIPO Patent Application WO/2011/068781

Kind Code:

A3

Abstract:

Disclosed herein is a method for cyclohexane oxidation. The method comprises a) forming a dispersion comprising liquid cyclohexane and an oxidant gas utilizing a high shear device, wherein the dispersion comprises oxidant gas bubbles with a mean diameter of less than about 5 µm, and wherein the high shear device comprises at least one rotor and at least one stator; and b) hydrogenating the dispersion in the presence of a hydrogenation catalyst to form a product comprising cyclohexanol or cyclohexanone. In some embodiments, the oxidant comprises air, oxygen-enriched air, oxygen, or an oxygen-containing gas. In some embodiments, step a) of the method comprises forming the dispersion in the presence of an oxidation catalyst. Also disclosed herein is a system for oxidizing cyclohexane.
