Claim 31:
32. The process of claim 1, further comprising a second oxidation step, wherein the second oxidation step comprises:
(ao) contacting a second oxidation feedstock comprising a second furanic oxidation substrate and a second oxidation solvent with oxygen in the presence of a second heterogeneous oxidation catalyst under conditions sufficient to form a second reaction mixture for oxidizing the second furanic oxidation substrate to produce a second FDCA pathway product, and producing the second FDCA pathway product;
wherein the first FDCA pathway product is an FDCA pathway intermediate compound, either alone or together with FDCA;
wherein the second furanic oxidation substrate is the first FDCA pathway product; and
wherein the second heterogeneous oxidation catalyst comprises a second solid support and a second noble metal, that may be the same or different from the first noble metal; and
(bo) recovering or isolating the second FDCA pathway product from the reaction mixture.
