OXIDATION PROCESS WITH IN-SITU H2O2 GENERATION AND POLYMER-ENCAPSULATED CATALYSTS THEREFOR

摘要

Catalysts useful for oxidation reactions are disclosed. The catalysts comprisea titanium zeolite, a transition metal, and a polymer, wherein at least one ofthe titanium zeolite or transition metal is encapsulated within a thin layerof the polymer. The catalysts are easy to prepare and use, they are easy torecover and reuse, and they provide good conversions in a variety of importantoxidation processes, including propylene epoxidation. The invention includes aprocess which comprises oxidizing an organic compound in the presence ofhydrogen, oxygen, and the catalyst, wherein the transition metal catalyzesformation of hydrogen peroxide in situ.
