Abstract
Hydrogen peroxide is prepared by the homogeneously catalyzed reaction of hydrogen and oxygen in an inert organic solvent, by employing a palladium complex, selected from palladium(O) complexes of dibenzylidene acetone, as the catalyst.
Claims8
In a process for producing hydrogen peroxide by the catalyzed reaction of hydrogen and oxygen, the improvement which comprises contacting gaseous hydrogen and oxygen with a two phase homogeneous catalysis system, which contains (i) an inert organic solvent phase having dissolved therein as the homogeneous catalyst a palladium(O) complex of dibenzylidene acetone and (ii) an aqueous solution as the second phase, for sufficient time to form hydrogen peroxide;
- extracting hydrogen peroxide reaction product from the organic phase into the aqueous phase;
- and recovering the aqueous phase containing hydrogen peroxide.
