“…To address this, BDSCCs are employed to catalyze the conversion of carbohydrates, such as fructose and glucose, into EMF, aiming to reduce the production cost of EMF (Table 6). 86,120 The sulfonated carbon catalyst derived from chicken bones, featuring an SO 3 H group quantity of 2.33 mmol g −1 , was utilized to convert HMF, fructose, and inulin into EMF. The results demonstrated impressive yields in the conversion reactions, with rates reaching 94.7%, 68.6%, and 63.6% for HMF, fructose, and inulin, respectively.…”

“…Emerging processes, such as using ball milling to oxidize biochar and thiomalic acid to synthesize sulfonated biochar with acidic functional groups like SO 3 H, show promise and are worth exploring. 86 Green sulfonation agents are another area for further exploration, as traditional agents like concentrated H 2 SO 4 may not align with the principles of green engineering. New functionalized reagents, similar to 5-sulfosalicylic acid, warrant investigation.…”

“…The huge consumption of traditional fossil fuels has led to serious environmental pollution problems and carbon emissions. , Biomass as the only renewable organic carbon resource has attracted more and more attention to replace traditional fossil resources. , Biomass consisting of lignocellulose has been converted to various renewable chemicals and fuels such as 5-hydroxymethylfurfural (5-HMF), , furfural, , levulinic acid (LA), , 5-ethoxymethylfurfural (5-EMF), − levulinate esters (LEs), , and so on . The major components of lignocellulose are often composed of C5 carbohydrates and C6 carbohydrates at the same time, which are difficult to separate and directly convert to the identical value-added chemicals in high selectivity.…”

As one of the substitutes for traditional fossil energy, the biomass resource has attracted extensive attention. Levulinate esters (LEs) are important green and high value-added chemical molecules. Catalytic routes based on acid catalysts are developed for the production of levulinate esters from various biomass-derived materials. In this review, the catalytic route for preparation of levulinate esters from C5/C6 carbohydrates is summarized. The effects of homogeneous and heterogeneous acid systems on the levulinate ester yields and the catalyst recyclability were expounded. The effect of reaction solvents and heating methods on LE selectivity was presented. Given the apparent differences in the synthesis of LEs with different heating methods in current publications, current challenges and prospects for the synthesis of LEs from biomass-derived compounds are provided. The lab-scale catalytic synthesis of levulinate esters from a biomass process has been developed. This review will facilitate and inspire future research on LE synthesis from biomass.

“…Many studies have been tried to use heterogeneous catalysts in green systems, since they can overcome such above-mentioned problems . Dowaki et al found that lignin-derived biochar with acidic functional groups (−COOH, −SO 3 H, and −OH) could catalyze well for selective conversion of fructose to 5-EMF (62% yield) at 115 °C for 6 h. Morales et al achieved to synthesize several sulfonic acid-functionalized heterogeneous catalysts for selective production of 5-EMF (63.4% yield) from fructose conversion at 116 °C for 4 h. Kumari et al successfully synthesized 5-EMF with a high yield (68%) under fructose dehydration at 120 °C for 8 h using heteropoly tungstate with tantalum ions. He et al reported that glucose transformation to 5-EMF could be well achieved over sulfated complex metal oxides catalyst with the existence of dual Brønsted-Lewis acidic properties.…”

In this work, ultrasonic-assisted ethanolysis of raw sugar (RS) into 5-ethoxymethylfurfural (5-EMF) product was performed under a biphasic system under mild conditions. The sulfonic-magnetic activated carbon (S-MAC) was prepared via pyrolysis and sulfonation processes and further applied for catalytic production of 5-EMF. The catalytic behaviors for facile formation/rapid production of 5-EMF were described through several factors such as type of catalyst, S-MAC and choline chloride (ChCl) adding amounts, reaction temperature, reaction time, and ultrasonic power generation. The integrating roles of various catalysts with the introduction of oxygen were described using turnover rate investigation, and the result found to be a great effect for improving the 5-EMF yield via major reactions such as hydrolysis, isomerization, dehydration, and etherification while side reactions for formation of polymeric intermediates were remarkably suppressed. Herein, a maximum yield of 5-EMF (actual yield = 93.2 ± 0.6%) was obtained at a low temperature of 80 °C and short reaction time for 11 min under an optimization process via linear-quadratic designs. Finally, the reusable systems under O2 and N2 addition were compared up to 10 cycles, and the result found that very few changing in 5-EMF yield could be obtained while hard carbon/humins deposited on S-MAC structure was significantly obstructed and reduced in each cycle via special oxidative degradation. In addition, lower energy consumption was required for regeneration of spent catalyst derived from reaction under an oxygen environment. This work was notably expected for further application in practical procedure under a reusable system.
