“…LA can be obtained through multi-step hydrolysis of six-carbon sugars such as cellulose, glucose or fructose in acidic aqueous solution, or through hydration and ring opening of biomass derived furfuryl alcohol (FOL). 13,14 Biomass conversion reactions in acidic aqueous solution oen face the problems of serious polymerization and low yields of target products. 15,16 In contrast, AL can be obtained by alcoholysis of sugars or FOL under acidic conditions with higher production efficiency and lower separation and purication cost.…”

“…In this method, 3‐mercaptopropyltrimethoxysilane (MTPS) is first subjected to an inter‐hydroxyl dehydration reaction with the hydroxyl groups on the catalyst carrier. Thus SH can be loaded on the support and then SH is oxidized to SO 3 H by hydrogen peroxide to synthesize the B acid‐containing solid acid catalyst 8,28 . Several researchers have used this method to prepare sulfonated catalysts for biomass hydrolysis.…”

BACKGROUND: Levulinic acid, an important platform compound, is extensively used in textiles, dyes, antifreeze, animal feed, solvents and food additives. However, the use of lignocellulosic biomass to produce levulinic acid is difficult because of poor accessibility to cellulose and low hydrolytic yield. Thus a viable hydrolysis strategy and a suitable catalyst must be developed.RESULTS: In this study, a bifunctional solid acid catalyst (HTC-SO 3 H) containing both cellulose binding sites ( Cl, COOH and OH) and catalytic sites ( SO 3 H) was prepared by a carbonization-grafting-oxidization method. X-ray photoelectron spectroscopy and Fourier transform infrared characterization confirmed the existence of Cl and the successful modification of the SO 3 H grafted hydrothermal carbon. The hydrogen bonds formed between cellulose and the binding sites ( Cl, OH and COOH) in the catalyst showed synergistic effects with the catalytic sites ( SO 3 H), leading to efficient hydrolysis of the furfural residue. A total of 74.81% (non-magnetic) and 70.18% (magnetic) levulinic acid yields were obtained after hydrolysis at 190 °C and 180 min in γ-valerolactone-H 2 O (1:1, v/v). Magnetic catalysts were synthesized using a co-precipitation method. Catalysts were recycled without any obvious reduction in catalytic activity. CONCLUSION: Using sucralose as a raw material, the as-synthesized bifunctional solid acid catalyst improved the accessibility to cellulose and increased levulinic acid yield. Moreover, the grafted SO 3 H formed by hydroxyl hydration condensation exhibited superior stability. This study provides a valuable strategy for the efficient hydrolysis of lignocellulosic biomass.

Biomass has been identified as the ultimate sustainable resource for all carbon‐based consumer products of the chemical industries in the future. Its catalytic conversion leads to the formation of various platform chemicals that could partially or even fully replace the fossil‐based building blocks that have been currently used in synthetic chemical processes. Among these compounds, levulinic acid (LA) has been recognized as a member of the "Top Value Added Chemicals from Biomass" and has attracted significant attention since the seminal paper reported by Werpy and Petersen in 2004. This review summarizes the properties, recent advances, and developments in the chemistry of levulinic acid. The production of LA from both plant and animal‐based carbohydrate feedstocks via 5‐hydroxymethylfurfural or furfuryl alcohol is discussed from a mechanistic perspective, highlighting intrinsic molecular‐level limitations to LA formation. The efficiencies of recently developed catalytic systems are also summarized and compared. Furthermore, the conversion of LA into high‐value‐added downstream chemicals, including its role in the synthesis of complex molecular structures, is overviewed. This section discussed the reactions of LA in the points of view of its various transformations on carbonyl‐, carboxy‐, methyl‐, and methylene functional groups. The reactions of these functionalities with C‐ ,N‐, O‐, and S‐nucleophiles, alcohols, amines, organometallic reagents, oxygen etc. were thematically summarized. Our review also outlooks to highlight the challenges and opportunities associated with the extensive research area of organic chemistry of levulinic acid.
