Chemoselective and re-usable heterogeneous catalysts for the direct synthesis of hydrogen peroxide in the liquid phase under non-explosive conditions and in the absence of chemoselectivity enhancers

Catalyst Pd/K2621 (K2621 = strongly acidic macroreticular resin from Bayer) is an effective catalyst for the direct synthesis of hydrogen peroxide in methanol at temperatures near 0 °C, under batch reactor conditions. Reaction conditions are non-explosive in character and no addition of selectivity enhancers is required. Selectivity up to 70% at 50% conversion is achieved.
