“…23 GVL, which is a stable chemical that does not oxidize or degrade at standard temperatures and pressures, is commonly used as a food additive and occurs naturally in fruits, with an industrial-level price of around $2/kg. 24 Ethyl lactate, which has a high boiling point of around 481 K and a low melting point of 242 K, has a cost typically around $2/kg, 17,25 making it competitive with petroleum-derived solvents. Alkanediols such as 1,2-ethanediol, 1,2-propanediol, and 1,6-hexanediol are a subgroup of diols characterized by low toxicity and biodegradability, making them a potential alternative to conventional solvents in various applications.…”

Improving the aqueous solubility of poorly soluble hydrophobic compounds is a topic of great interest to the pharmaceutical, chemical, and food industries. The poor solubility of these compounds in water poses a challenge in developing sustainable processes for their extraction, separation, and formulation. Therefore, in this study, the use as hydrotropes of biobased solvents such as γ-valerolactone (GVL), Cyrene, ethyl lactate, and alkanediols (1,2-propanediol, 1,5-pentanediol, and 1,6-hexanediol) to improve the solubility of two model compounds (syringic acid and ferulic acid) in water is investigated. The effects of the concentration and structure of biobased solvents on the solubility of phenolic compounds in aqueous solutions at (303.2 ± 0.5) K were studied. The results showed that the aqueous solubility of the phenolic compounds studied typically increased with the log (K OW) of the hydrotrope (1,2-propanediol < Cyrene < 1,5-pentanediol < GVL < ethyl lactate < 1,6-hexanediol) and the hydrophobicity of the solute; the hydrotropic dissolution of phenolic compounds is shown to depend on both the hydrotrope and the solute. This study shows that some biobased solvents, especially GVL, are excellent hydrotropes. Their renewable nature, low price, and low toxicity make these results particularly relevant to the field of extraction and separation of bioactive compounds.

“…To consider how those studies could affect production methods for 5-EMF, a summary of technoeconomic analyses (TEAs) studied on biomass-derived chemicals (furans, 5-hydroxymethylfurfural (5-HMF), 2,5-dimethylfuran (DMF), 2,5-furandicarboxylic acid (FDCA), or γ-valerolactone (GVL)) were compiled (Table ). As 5-HMF is a biomass-derived feedstock dehydration product, − furans (furfural or 5-HMF) are the C5/C6 carbohydrates dehydration–isomerization product . In considering the relationship between the products (Table ) and 5-HMF, 2,5-dimethylfuran (DMF) is the 5-HMF hydrogenation product, and 2,5-furandicarboxylic acid (FDCA) is the 5-HMF oxidation product. , Supposing that the price of 5-EMF is the same as that of 5-HMF or just a little higher, from the values in Table , it is likely that the minimum price of 5-EMF would be around $2/L.…”

Renewable resources must be upgraded to platform chemicals and biofuels, especially furanic compounds such as 5-hydroxymethylfurfural (5-HMF) and 5-ethoxymethylfurfural (5-EMF), to meet the needs of a sustainable society. This review examines chemocatalytic approaches to 5-EMF via alcoholysis of 5-(halomethyl)furfural or etherification of 5-HMF with attention being given to direct catalytic conversion of biomass-derived materials into 5-EMF. Emphasis is placed on the reaction mechanisms and pathways with either homogeneous or heterogeneous catalysts to provide recommendations for catalytic system development. A multicriteria assessment evaluation tool as a sustainability assessment method for the synthesis of 5-EMF routes from biomass is given. Potential research directions include the direct synthesis of 5-EMF from biomass-derived compounds in innovative reaction systems and technoeconomic studies on 5-EMF production.

“…As a result, the HMF yield was only 8% from cellulose hydrolysis with the production rate of 54 kg HMF per hour, while 13% of the biomass was converted into by‐products, and the rest is the unreacted biomass, which later will be as a feedstock (including humins) for the combustion to generate energy. However, the latest study from R. P. Bangalore Ashok et al 171 demonstrated that lignocellulosic biomass from spruce to produce γ‐valerolactone (GVL), 2‐methyltetrahydrofuran (2‐MTHF) and HMF. Because each product from this proposed process (as shown Figure 9) has a lower minimum selling price (MSP) than its average market price, this strategy is considered a potential biorefinery approach.…”

Summary 5‐Hydroxymethylfurfural (HMF) is a versatile biomass‐derived chemical from multifunctional compound. It is also a promising intermediate compound used in various chemical and fuel applications, including pharmaceuticals, solvents, biofuel, and other intermediates. The demand for innovative approaches to renewable energy resources has risen to diminish the dependency on petroleum‐based products and to seek economical and environmentally friendly processes for supplying energy to the world. Fructose, glucose, cellulose, and lignocellulosic materials are the most common feedstocks used to synthesize HMF. This study reviews previous studies on the development of high yield and selectivity of HMF from technical and economic perspectives. The article highlights a few significant parameters and focused on the solvent system used for the synthesis of HMF in the lab scale and through the development of process modeling using simulation software such as Aspen Plus to perform the techno‐economic analysis (TEA), which analyses the economic feasibility of the developed production process. The TEA can estimate the capital investment needed, including feedstock, catalyst, and equipment cost, and the final product's minimum selling price (MSP). HMF is cost‐efficient due to higher operational costs from the higher cost of fructose feedstock. By studying this analysis, the overall cost of HMF production can be minimized and more economically competitive with current commercial production. Besides, to make the production of HMF more cost‐effective, more research into alternative lignocellulosic feedstocks and the development of novel catalytic systems is needed.
