In this invention, a process to obtain hydrogen peroxide solutions by means of the direct reaction of hydrogen and oxygen in the presence of a solvent and of catalysts constituted from noble or semi-noble metals, or combinations of several of these metals, supported on a halogen-free acid resin, is described.

Process to obtain hydrogen peroxide

Oxidized compounds are produced in a continuous integrated process in liquid phase, which comprises: Step I, synthesis of non acidic hydrogen peroxide solutions by direct reaction between hydrogen and oxygen by catalytic reaction utilizing a noble metal catalyst. Step II, this hydrogen peroxide solution is directly mixed with an organic substrate, a suitable catalyst and optionally a solvent. The integrated process requires no treatment step and is particularly well adapted to the production of propylene oxide.
