Method & Evidence

AimTo investigate the efficiency of continuous flow microreactors versus batch reactors for the synthesis of 5-hydroxymethylfurfural (HMF) from fructose using deep eutectic solvents.

MethodComparative experimental study

ProcedureFructose was converted to HMF using a deep eutectic solvent (choline chloride/ethylene glycol) and HCl catalyst. The reaction was performed in both batch reactors and continuous flow microreactors, with and without an extraction solvent (MIBK) to form a biphasic system. Reaction parameters such as temperature, time, catalyst loading, and solvent ratios were optimized.
