Summary: The study demonstrated the efficient conversion of glucose to 5-HMF in ionic liquids with MoCl3 as catalyst under microwave irradiation, with the ionic liquid [BMIM]Cl proving to be the best solvent. Microwave irradiation not only reduced the reaction time and improved the yield of 5-HMF compared to traditional oil-bath heating, but also accelerated the bond breaking processes in the reaction.

Summary: In this study, the process engineering aspects of producing 5-hydroxymethylfurfural (5-HMF) from Bambusa bamboo using CrCl3 catalyst and ionic liquid ([Bmim]Cl) in a batch reactor were explored in detail. The highest yield of 5-HMF (25%) was obtained at a reaction temperature of 120℃ and a stirring speed of 1200 rpm. Additionally, operating the reactor at high stirring conditions (reaction-limited regime) significantly improved the reaction rate constants (k(1), k(2), k(3)). It is suggested that operating at a stirring speed >1100 rpm and a temperature <120℃ in the batch reactor will maximize the production of 5-HMF from Bambusa bamboo.

Summary: In this study, a class of benzenesulfonic acid-grafted metal-organic frameworks with strong acidity and hydrophobicity were successfully prepared and applied in the catalytic conversion of fructose to HMF. Due to its better hydrophobicity and oleophilicity, the hydrophobic MOF exhibited higher catalytic activity and selectivity in the HMF synthesis.

Summary: A novel imidazolium-based basic ionic liquid [PEMIM][OH] was synthesized for the efficient and recyclable multicomponent synthesis of tetrahydrobenzo[b]pyran derivatives, showing high yields in aqueous media. The use of halide and metal-free catalyst establishes a sustainable process, while cost-effective isolation of pure products was achieved by avoiding column chromatography and recrystallization.

Summary: A new strategy is proposed to enhance the catalytic activity of cross-linked chitosan beads by functionalizing them with vinyl and polymerizing them with 1-vinyl-3-butylimidazolium bromide to create a polyionic liquid on the beads. The resulting composite serves as a metal-free catalyst for various organic transformations with high efficiency and recyclability. Comparative studies show that the activity of this composite is superior to that of cross-linked bead and polyionic liquid.

Summary: A novel renewable taurine-based ionic liquid ([TauIm][HSO4]) was synthesized and used to produce ethyl levulinate (EL) from various lignocellulosic substrates under microwave irradiation. The optimized conditions were applied to different biomasses, with raw sugarcane bagasse (SCB) showing the highest EL yields due to its higher hemicellulose content. These results provide new possibilities for biomass valorization using renewable and straightforward routes.

Summary: Recent advances in the transformation of biobased 5-hydroxymethylfurfural to 2,5-dimethylfuran, a potential liquid fuel, have been critically summarized. The highest yields were obtained using bimetallic Cu-Co supported on carbon or Ni supported on mesoporous carbon under specific reaction conditions. The ideal catalyst should have high metal dispersion and some acidity to promote both hydrogenation and hydrogenolysis, while minimizing the formation of byproducts.
