実験手順
A 100 mL pressure vessel with a glass liner and an impeller was charged with 1.87 g of furan-2,5-dicarboxylic acid, 0.5 g of 4% Pd/Silica and 40 mL of acetic acid. The pressure vessel was purged 3 times with nitrogen, and 2 times with hydrogen. The vessel was then pressurized to 750 psig hydrogen and heated to 140° C. for 3 hours. After cooling the vessel was vented and the solids were separated by filtration. The acetic acid solution was evaporated under vacuum to provide 1.68 g (88% yield) of tetrahydrofuran-2,5-dicarboxylic acid.
