“…The difficulty regarding product separation is tied to low solubility in the aqueous phase, resulting in low HMF yield [27]. Based on this problem, an alternative is needed to substitute organic solvent in biomass conversion, and one of the potential solutions is by using ionic liquid (IL) [29], [31].…”

“…IL is an organic or inorganic salt that possesses some interesting properties such as its low melting point of under 100 °C, non-flammable, chemical stability, high thermal stability, low vapor pressure, and environmentally friendly as either catalyst or solvent [26], [29]. Moreover, ILs can be tuned to comply with a particular task by changing their cation and anion combination [32], [33].…”

Biomass has been used as a raw material to replace fossil fuel due to its abundance and renewability in recent years. The majority of biomass consists of carbohydrates such as glucose and fructose. The conversion of glucose into its derivative (i.e., 5-hydroxymethylfurfural (HMF)) opens several spaces to be studied. However, the yield of HMF is still low due to its ease of degradation into by-products and the difficulty of product separation. Therefore, ionic liquid (IL) is used as a solvent or media to avoid HMF degradation, which has high thermal stability, low toxicity, an un-flammable, wide range of solubility, physical and chemical stability. In addition, IL is recyclable, has good performance at dissolving biomass, and can act as a catalyst. Many important aspects of glucose conversion into HMF in IL as a media and catalyst can be deeply developed and investigated regarding conversion yield, which is affected by different ILs used, and conversion time. This review paper will discuss a detailed summary of the development of glucose conversion into HMF using IL.

“…[1][2][3][4][5] 2,5-Dimethylfuran has been regarded as a potential platform chemical, which is easily prepared by the hydrodeoxygenation of 5-hydroxymethylfurfural (HMF). [2,[6][7][8] As seen in Figure 1, HMF has been known as an essential raw material in the production of valuable compounds such as levulinic acid, [9][10][11] 2,5-furandicarboxaldehyde and 2,5-furandicarboxylic acid, [12][13] 1,5-bis(5-(hydroxymethyl)furan-2-yl)penta-1,4-dien-3-one [14] , which are known as key precursors for biofuel, polymers, and energy technology. However, high cost is the main obstacle hindering the commercialization of HMF ($1119.30/100 g, 99 % purity, Sigma-Aldrich).…”

5-Hydroxymethylfurfural (HMF), a versatile intermediate from biomass, can be applied to prepare a wide range of valuable compounds in the petroleum and chemical industries. Thus, simple, fast, and practical methods to convert carbohydrates into HMF have been capturing increasing attention. We reported herein a method of using p-toluenesulfonic acid (p-TsOH) and Brønsted acidic ionic liquid as catalysts for the dehydration of fructose in dimethyl sulfoxide (DMSO) under a continuous flow process. The effect of the various reaction conditions on HMF formation was investigated, and the HMF yields were determined by the HPLC method. The results showed that p-TsOH and Brønsted acidic ionic liquid are effective catalysts within short residence times. This study provides a simple and safe procedure that can be potentially performed on a large scale to synthesize HMF from fructose.

“…The difficulties in the separation of HMF from other side products due to low solubility in the aqueous phase also lead to a decrease in HMF yield [6,23,24]. Therefore, several new technologies are required to improve the glucose dehydration and separation processes, for example, the use of ionic liquid (IL)-based processes or combining IL and membrane separation technology [25][26][27][28][29].…”

Several notable applications of ILs include the use as a solvent or media in biomass conversion, as a catalyst for reaction, as corrosion inhibitors, and as a supporting material in membrane separation [3,14,[25][26][27]30]. IL can act as a green solvent, with a wide range of solubility, and as a catalyst to increase the HMF yield [3,[25][26][27]34].…”

Conversion of Glucose to 5-Hydroxymethylfurfural, Levulinic Acid, and Formic Acid in 1,3-Dibutyl-2-(2-butoxyphenyl)-4,5-diphenylimidazolium Iodide-Based Ionic Liquid

The separation process between 5-hydroxymethylfurfural (HMF) and trace glucose in glucose conversion is important in the biphasic system (aqueous–organic phase), due to the partial solubility property of HMF in water. In addition, the yield of HMF via the dehydration reaction of glucose in water is low (under 50%) with the use of Brønsted acid as a catalyst. Therefore, this study was conducted to optimize the production and separation of products by using a new hydrophobic ionic liquid (IL), which is more selective than water. The new IL (1,3-dibutyl-2-(2-butoxyphenyl)-4,5-diphenyl imidazolium iodide) [DBDIm]I was used as a solvent and was optimized for the dehydration reaction of glucose to make a more selective separation of HMF, levulinic acid (LA), and formic acid (FA). [DBDIm]I showed high performance as a solvent for glucose conversion at 100 °C for 120 min, with a yield of 82.2% HMF, 14.9% LA, and 2.9% FA in the presence of sulfuric acid as the Brønsted acid catalyst.
