“…The results are summarized in Table 1. As commonly observed in carbohydrate chemistry, 14,24 when the fructose content was decreased from 20 to 5 wt%, the yield of DFF was increased from 77 to 84% (Table 1, entries 1 and 2). In contrast, when the fructose content was increased from 20 to 50 wt%, the yield of DFF decreased from 70% to 57% (Table 1, entries 2 and 3).…”

Here we report the one pot conversion of fructose to DFF in the presence of a mixture of choline chloride (ChCl) and DMSO as a solvent and Mo-Keggin heteropolyacids.Here we demonstrate that choline chloride has a beneficial effect on the direct conversion of fructose and inulin to DFF in the presence of Mo-V containing Keggin heteropolyacid. ChCl have two beneficial effects : 1) the enhancement of the conversion of fructose to HMF and 2) a higher conversion of HMF to DFF. A yield to DFF of 84% was obtained from fructose in the optimized conditions. In this mixture inulin was also converted to DFF.

In this Minireview, the state of the art in the use of ionic liquids (ILs) and deep eutectic solvents (DESs) as alternative reaction media for biocatalytic processes and biomass conversion is presented. Initial, proof-of-concept studies, more than a decade ago, involved first-generation ILs based on dialkylimidazolium cations and non-coordinating anions, such as tetrafluoroborate and hexafluorophosphate. More recently, emphasis has switched to more environmentally acceptable second-generation ILs comprising cations, which are designed to be compatible with enzymes and, in many cases are derived from readily available, renewable resources, such as cholinium salts. Protic ionic liquids (PILs), prepared simply by mixing inexpensive amines and acids, are particularly attractive from both an environmental and economic viewpoint. DESs, prepared by mixing inexpensive salts with, preferably renewable, hydrogen-bond donors such as glycerol and amino acids, have also proved suitable reaction media for biocatalytic conversions. A broad range of enzymes can be used in ILs, PILs and DESs, for example lipases in biodiesel production. These neoteric solvents are of particular interest, however, as reaction media for biocatalytic conversions of substrates that have limited solubility in common organic solvents, such as carbohydrates, nucleosides, steroids and polysaccharides. This has culminated in the recent focus of attention on their use as (co)solvents in the pretreatment and saccharification of lignocellulose as the initial steps in the conversion of second-generation renewable biomass into biofuels and chemicals. They can similarly be used as reaction media in subsequent conversions of hexoses and pentoses into platform chemicals.
