Claim 0:
1. A process for producing a first 2,5-furandicarboxylic acid (FDCA) pathway product from a first furanic oxidation substrate, the process comprising:
providing a crude oxidation substrate comprising a first furanic oxidation substrate, a first oxidation solvent and one or more additional components;
separating the one or more additional components from the crude oxidation substrate to form a first oxidation feedstock comprising the first furanic oxidation substrate and the first oxidation solvent; and
(a) contacting the first oxidation feedstock with oxygen in the presence of a first heterogeneous oxidation catalyst under conditions sufficient to form a reaction mixture for oxidizing the first furanic oxidation substrate to a first FDCA pathway product, and producing the first FDCA pathway product;
wherein the first oxidation solvent is a multi-component solvent comprising water and a water-miscible aprotic organic solvent;
wherein no base is added to the reaction mixture during (first) contacting step (a); and
wherein the first heterogeneous oxidation catalyst comprises a first solid support and a first noble metal; and
(b) recovering or isolating the first FDCA pathway product from the reaction mixture.
