“…[9] FDMC can be synthesised via esterification of FDCA; patent literature shows examples of incorporating the esterification step into FDCA synthesis and purification process. [10,11] FDMC can also be obtained from HMF directly by an oxidative esterification of HMF in methanol. High yields of FDMC have been obtained with both noble metal and non-noble metal catalysts.…”

2,5‐furandicarboxylic acid (FDCA) is one of the most attractive emerging renewable monomers, which has gained interest especially in polyester applications, such as the production of polyethylene furanoate (PEF). Recently, the attention has shifted towards FDCA esters due to their better solubility as well as the easier purification and polymerisation compared to FDCA. In our previous work, we reported the synthesis of FDCA butyl esters by dehydration of aldaric acids as stable intermediates. Here, we present the synthesis of FDCA methyl esters in high yields from pectin‐based galactaric acid using a solid acid catalyst. The process enables high substrate concentrations (up to 20 wt%) giving up to 50 mol% FDCA methyl esters with total furancarboxylates yields of up to 90 mol%. The synthesis was successfully scaled up from gram‐scale to kilogram‐scale in batch reactors showing the feasibility of the process. The stability of the catalyst was tested in re‐use experiments. Purification of the crude product by vacuum distillation and precipitation gave furan‐2,5‐dimethylcarboxylate with a 98% purity.
