“…The hydrogen-bond interaction between glucose and ChCl was possibly formed, which was detected in ESI-MS. The possible direct conversion of glucose to HMF over Brönsted acid catalysts can be through the dehydration to form levoglucosan as an intermediate in the organic solvent system at a high temperature (Figure ), , yet the intermediate levoglucosan was not detected in this system because the formation of levoglucosan was difficult under the low reaction temperature in the EMS–SAN system. Hence, the glucose was not dehydrated directly to produce HMF in this catalytic system.…”

A eutectic mixture solvent (EMS) system containing 1,4-butylene glycol (1,4-BDO), choline chloride (ChCl), and sucrose was proposed for the conversion of sucrose to 5-hydroxymethylfurfural (HMF) with mesoporous hollow silica−alumina nanosphere (SAN) catalyst. The EMS system can form a solid at room temperature after the reaction since the adequate composite proportion of EMS components is conducive to the separation of the product and the recovery of the solvent system. The reaction mechanism of the EMS−SAN system that catalyzed the conversion of sucrose was detailed by nuclear magnetic resonance, electrospray ionization mass spectra experiments, and density functional theory calculation. The complete conversion of sucrose benefits from the hydrogen-bond interaction between 1,4-BDO, ChCl, and sucrose system as well as the synergistic effect of Bronsted and Lewis acid sites on SAN catalyst. The hydrogen-bond interaction energy in the sucrose−1,4-BDO−ChCl system was −55.28 kcal mol −1 , implying that the higher hydrogen bond energy between sucrose and EMS components improved the HMF formation.

Aqueous conversion of monosaccharides to furans: were we wrong all along to use catalysts?

“…Disaccharides and polysaccharides are more difficult to use to prepare HMF than monosaccharides due to their structural complexity. − Sucrose, maltose, cellobiose, and lactose are disaccharides commonly found in biomass. Sucrose is widely found in sugar cane and sugar beet, which consists of a fructose unit and a glucose unit connected by α,β-1,2-glycosidic bonds.…”

Critical Review on the Preparation of Platform Compounds from Biomass or Saccharides via Hydrothermal Conversion over Carbon-Based Solid Acid Catalysts

The use of carbon-based catalysts to catalyze the hydrothermal conversion of biomass and its derived carbohydrates to produce platform compounds such as 5-(hydroxymethyl)furfural (HMF), levulinic acid (LA), and furfural (FF) has a long history. The excellent thermal stability and chemical activity and low preparation cost of carbon-based catalysts make them develop rapidly in catalytic hydrothermal conversion, which is the core attention in the review. Carbon catalysts are divided into sulfuric acid-based carbon catalysts, phosphoric acid-based carbon catalysts, metal-supported carbon catalysts and other types of carbon catalysts, to study their application to hydrothermal decomposition of monosaccharides, disaccharides, polysaccharides, and biomass. The characteristics of different types of carbon catalysts were introduced. The diversified development of carbon-based catalysts and the upgrading of feedstocks have promoted the improvement of product selectivity, cost, and energy optimization, realizing the transformation of hydrothermal decomposition of biomass into a greener process. However, the development of efficient catalytic systems for hydrothermal conversion of abundant, cheap, and readily available biomass sources is still an ideal choice to expand the process strategy.
