  • Integrated process for selective oxidation of organic compounds
    Patent number: 6822103
    Abstract: 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.
