Effective selectivity conversion of glucose to furan chemicals in the aqueous deep eutectic solvent

The growing demand for energy and materials in modern society pushes scientific research to finding new alternative sources to traditional fossil feedstocks. The exploitation of biomass promises to be among the viable alternatives with a lower environmental impact. Making biomass exploitation technologies applicable at an industrial level represents one of the main goals for our society. In this work, the most recent scientific studies concerning the enhancement of lignocellulosic biomasses through the use of deep eutectic solvent (DES) systems have been examined and reported. DESs have an excellent potential for the fractionation of lignocellulosic biomass: the high H-bond capacity and polarity allow the lignin to be deconvolved, making it easier to break down the lignocellulosic complex, producing a free crystallite of cellulose capable of being exploited and valorised. DESs offer valid alternatives of using the potential of lignin (producing aromatics), hemicellulose (achieving furfural) and cellulose (delivering freely degradable substrates through enzymatic transformation into glucose). In this review, the mechanism of DES in the fractionation of lignocellulosic biomass and the main possible uses for the valorisation of lignin, hemicellulose and cellulose were reported, with a critical discussion of the perspectives and limits for industrial application.

“…[21,67] A biphasic aqueous DES [3ChCl : gluucose] (w/w) and cosolvent EtAc system was formed and in situ intensified glucose conversion catalyzed by CrCl 3 . [67] High HMF yield of 52.9 % was obtained from a high glucose concentration (20 wt %) at 120 °C for 12 h. A green aqueous NADES and MIBK biphasic system was also used to intensify the synthesis of HMF from glucose in the presence of a little amount of SnCl 4 . [21] HMF yield was 64.3 % at 130 °C for 2 h in the biphasic system and glucose dosage in the [2ChCl : glucose] was high to 30 wt %.…”

5-Hydroxymethylfurfural (HMF) is identified as an important bio-based platform chemical to bridge petroleum-based and biomass-based resources. It can be obtained through dehydration of various carbohydrates as well as converted to valueadded fuels and chemicals. As designer solvents, ionic liquids (ILs) and deep eutectic solvents (DESs) have been widely used in catalytic transformation of biomass derivatives to various chemicals. This Review summarizes recent progress in experimental and theoretical studies on dehydration of carbohy-drates such as fructose, glucose, sucrose, cellobiose, chitosan, cellulose, inulin, and even raw biomass to generate HMF using ILs and DESs as catalysts/cocatalysts and/or solvents/cosolvents. It also gives an overview of IL and DES-involved catalytic transformation of HMF to downstream products via oxidation, reduction, esterification, decarboxylation, and so forth. Challenges and prospects of ILs and DESs are also proposed for further production of HMF and HMF derivatives from biomass in green and sustainable processes.

“…Glucose, the most abundant and least expensive available monosaccharide, has a price advantage over fructose or HMF for EMF production. 32 The one-pot transformation of glucose to EMF would be an economically more feasible process, because it avoids the isolation of HMF or fructose and the subsequent purication steps. Currently, single catalysts (e.g., ionic liquids), 33 Al(DS) 3 (aluminum tridodecyl sulfate), 34 multifunctional zeolites 35 ) or paired catalysts (e.g., H-USY(Si/Al ¼ 6) + Amberlyst-15, 13 AlCl 3 $6H 2 O + PTSA-POM (polymer of p-toluenesulfonic acid (PTSA) and paraformaldehyde (POM)) 36 have been tested for EMF production from glucose.…”
