Yield:1883-75-6 100%

Reaction Conditions:

with hydrogen;3mol% Pt/C in ethanol at 20; under 3750.38 Torr; for 48 h;Product distribution / selectivity;

Example 4.; Batch experiment with hydrogenation/etherification of 5- ( hy d roxy methyl )f u rf u ra I In a 7.5 ml batch reactor, 0.06 mmol 5-(hydroxymethyl)furfural (HMF) in 1 mL ethanol and 5 bars of hydrogen was reacted with 3 mol% of a Pt/C catalyst for 2 days at room temperature. The starting material was completely converted in 100% selectivity to 2,5- di(hydroxymethyl)furan. Subsequently, the mixture was heated to 75 0C for 1 day without hydrogen. The 2,5-di(hydroxymethyl)furan was fully converted and 2,5- bis(ethoxymethyl)furan was obtained in 75% yield. 25% Side products are ring opened levulinate derivatives. The experiment was successfully repeated on a 20 gram scale.
