<p>This invention is a process for oxidizing an organic compound with a hydrogen peroxide solution produced by reacting hydrogen and oxygen in the presence of an oxidation catalyst. The hydrogen peroxide is produced by reacting hydrogen and oxygen in a solvent in the presence of a H<SUB>2</SUB>O<SUB>2</SUB>-producing catalyst comprising a polymer-encapsulated combination of a noble metal and an ion-exchange resin. Polymer encapsulation of the H<SUB>2</SUB>O<SUB>2</SUB>-producing catalyst improves its productivity in making hydrogen peroxide and is expected to reduce metal loss.</p>
