Reaction Steps

An aqueous solution containing 10 wt % glucose and 10 wt % fructose (3 mL, 0.0022 mol glucose, 0.0023 mol fructose) was mounted in an Ace vial pressure tube (stable to ˜20 Bar). Solid NaCl (150 mg, 0.0026 mol) was dissolved in the aqueous phase followed by the addition of MIBK (12 ml) as extracting solvent. The pressure stable tube was sealed and heated to 160° C. for 105 min and subsequently allowed cooling to room temperature. A sample of the reaction mixture was collected and filtered through a syringe filter (0.45 μm PTFE), mixed with an internal standard (i-PrOH) and analyzed via HPLC. The results of the HPLC showed 80% glucose from glucose, 0.0018 mol; 4% fructose from fructose, 9.5·10−5 mol; 64% HMF from fructose, 0.0015 mol; total sugar conversion 59%; HMF selectivity from fructose 67%.
