    Abstract: A process for the selective oxidation of olefins to epoxides comprising the step of contacting the olefin (propylene) with an oxidant (hydrogen peroxide) in the presence of a Lewis acid oxidation catalyst (MTO), organic base (pyridine or its N-oxide), in a solvent system comprising an organic water-miscible solvent (methanol); and adding a pressurizing gas (nitrogen) to increase the pressure, whereby olefin is further dissolved in organic solvent system to increase the selectivity and yield of the desired epoxide (propylene oxide).

    Abstract: A process is provided for carrying out an oxidation on a feed including levulinic acid and/or a levulinic acid oxidation precursor to succinic acid, one or more furanic oxidation precursors of 2,5-furandicarboxylic acid and a catalytically effective combination of cobalt, manganese, and bromide components for catalyzing the oxidation of the levulinic acid component and of the one or more furanic oxidation precursors to produce both succinic acid and 2,5-furandicarboxylic acid products, which process comprises supplying the feed to a reactor vessel, supplying an oxidant, reacting the levulinic acid component and the one or more furanic oxidation precursors with the oxidant to produce both succinic acid and 2,5-furandicarboxylic acid (FDCA) and then recovering the succinic acid and FDCA products. A crude dehydration product from the dehydration of fructose, glucose or both, including 5-hydroxymethylfurfural, can be directly oxidized by the process to produce 2,5-furandicarboxylic acid and succinic acid.
