“…[12] In contrast, a Fe-pillared montmorillonite catalyst was found to be very active and able to convert glucose quantitatively, though with low selectivity of 20 % to levulinic acid. [13] Instead a much higher amount of formic acid as well as a significant amount of coke was observed in this study. [13] To circumvent the drawback of thermal instability and to improve the yield of levulinate, we were inspired to explore the use of ionic liquids as catalysts for these reactions.…”

“…In contrast, reactions of water-soluble sugars with solid acid catalysts have been extensively studied [8,14,65,78,87,88,115]. In general, the heterogeneous catalytic system could convert water-soluble sugars to organic acids by shape-selective, solid acid-catalyzed processes at low temperatures.…”

The transition from today's fossil-based economy to a sustainable economy based on renewable biomass is driven by the concern of climate change and anticipation of dwindling fossil resources. Although biofuels are the central theme of the transition, biomass resources cannot completely replace petroleum. It is projected that biofuels can only supply up to 30 % of today's transportation fuel market even if all available domestic biomass resources are used for the production of liquid fuels. Therefore, transformation of biomass into high-value-added chemicals is advantageous to secure optimal use of the abundant, but limited, biomass resources from the economical and ecological perspective. Industry is increasingly considering bio-based chemical production as an attractive area for investment. The potential for chemical and polymer production from biomass is substantial. The US Department of Energy recently issued a report which listed 12 chemical building blocks considered as potential building blocks for the future. Organic acids (e.g., succinic, lactic, levulinic acid, etc.) are among the widely spread ''platform-molecules,'' which may be further converted into possibly derivable high-value-added chemicals. The transition from a fossil chemical industry to a renewable chemical industry will likewise depend on our ability to focus research and development efforts on the most promising alternatives. In this chapter, we review the emerging technologies on catalytic conversion of biomass to value-added organic acids in aqueous media.

“…A quantitative conversion of glucose was observed over Fe-pillared montmorillonite catalyst, but the selectivity to levulinic acid was only 20 % and a large amount of humins were also observed in this study. [13] Recently, Peng et al reported that glucose can be directly converted to ethyl levulinate (ELevu) over sulfated zirconia catalysts with a moderate yield up to 30 % at 200 8C. [14] Furthermore, we found that sulfonic acid functionalized ionic liquids and solid Brønsted acids are more promising catalysts for the conversion of fructose to ELevu in ethanol than for the analogous conversion to levulinic acid in water.…”

Caught in an acid trap! Zeolites with moderate acidity are demonstrated to be versatile and reusable solid‐acid catalysts for the transformation of biomass derived carbohydrates to alkyl levulinates in alcohol solvents. In short‐chained alcohols it proved possible to obtain significantly higher yields of alkyl levulinates, than what is achievable of levulinic acid in analogous reactions performed in water.
