Abstract
The invention relates to a method for oxidizing organic substrates using 1O2 in which hydrophobic organic substrates that react with 1O2 are added to an organic solvent in the presence of a heterogeneous or homogeneous catalyst with 30–70% being compr Afterwards, H2O2 is catalytically decomposed into water and 1O2, and the oxidation into corresponding oxidation products ensues.
Claims5
A process for the oxidation of organic substrates by means of 1O2, which consists of adding 40–60% strength H2O2 to hydrophobic organic substrates which react with 1O2 in a monohydric C1–C8 alcohol as a solvent in the presence of 5–25 mol % of a homogeneous molybdate catalyst, whereupon H2O2 is catalytically decomposed to give water and 1O2, oxidizing said substrate to the corresponding oxidation products with precipitation of the catalyst, removing said precipitated catalyst by centrifugation or filtration and recycling said catalyst to said oxidation.
