“…The first HMF synthesis in DMSO was reported in 1980 with 90% of HMF yield catalyzed by solid resin Diaion PK-216. 19 After which, DMSO, as well as some other polar aprotic solvents (sulfolane, 20 DMF, 21 ethers 22 ), have been widely studied for HMF synthesis under various conditions. New types of catalysts, such as BF 3 •OEt 2 21 and NH 4 Cl (NH 4 HSO 4 ), 20 were tested in fructose dehydration in organic solvents.…”

5-Hydroxymethylfurfural (HMF) has been known as a product from hexose dehydration for over 100 years and is considered to be one of the most promising platform molecules that can be converted into a variety of interesting chemicals. HMF, together with furfural and 2,5-furandicarboxylic acid (FDCA) are derivatives of furan compounds, which were listed as the top 10 value-added bio-based chemicals by the US Department of Energy. The great and increasing interest in the production of furan derivatives from biomass resources is due to the great potential of furan derivatives as feedstock for bulk chemicals and fuels. HMF can be synthesized by dehydration of all types of C6 carbohydrates, including monomeric and polymeric carbohydrates, such as fructose, glucose, sucrose, starch, inulin, cellulose, and raw biomass.Numerous improvements and milestones have been made in the dehydration process during the past 130 years. The big challenge for the process of HMF production is its suitability for industrial scale yet being cost efficient. This perspective article will review the HMF development timeline, focusing on the important events, landmark contributions, engineering and practical challenges of HMF production.

“…HCl and H 3 PO 4 can also catalyze fructose dehydration in subcritical water, resulting in a HMF yield of 40-50% [12]. Organic acids such as oxalic acid, levulinic acid and p-toluenesulfonic acid were attempted as well [13][14][15][16]. In addition, Ionic liquids were also designed and applied in the conversion of carbohydrates to HMF [17].…”

“…Since Dü ll and Kiermeyer independently introduced a method of synthesis of HMF in 1895, 8 many researchers reported different preparation methods along with application of homogeneous and heterogeneous acids both in aqueous and non-aqueous media. Some examples are the following: mineral acids [9][10][11] (H 2 SO 4 , HCl, and H 3 PO 4 ), organic acids [12][13][14][15][16] (oxalic, levulinic, p-toluenesulfonic, and maleic acids), Lewis acids (ZnCl 2 , AlCl 3 , and BF 3 ), salts (NH 4 SO 4 / SO 3 , pyridine=PO 4 3À , pyridine/HCl, and also Al, Th, Zr, lanthanide ions), [17][18][19][20] and solid catalysts 6,21-24 (ionexchange resins, zeolites, and metal(IV) phosphates), which were all commonly used in the production of HMF.…”
