CrCl3 · 6H2O and Boric Acid as a New Catalytic System: Enhanced 5-Hydroxymethylfurfural Production from Cellulose Under Milder Conditions
Here, we present a new catalytic system to produce 5-hydroxymethylfurfural (HMF) from cellulose under milder conditions (<140 °C). A high 5-hydroxymethylfurfural (HMF) yield of 45 mol% was achieved by direct hydrolysis, isomerization, and dehydration of cellulose in [BMIM]Cl
at 120 °C for 2 h with the presence of CrCl3 · 6H2O as the catalyst. The optimized ratio of CrCl3 · 6H2O/boric acid was determined to be 10/50 mol% based on cellulose loading. We also found that when the reaction time was increased
it would reduce HMF production and lead to the formation of levulinic acid and formic acid.
