Summary: This study successfully utilized sucrose from sorghum syrup to synthesize HMF, mainly by catalytically hydrolyzing sucrose to glucose and fructose, and dehydrating hexoses to yield HMF. After optimizing the reaction parameters, a maximum HMF yield of 65% was achieved, with unreacted glucose used for microbial cell enrichment, potentially enabling complete utilization of carbohydrates from sorghum plants.

Summary: A facile high-yield, solvent-free approach for the synthesis of a series of 1-(hydroxymethyl)-pyrazoles under microwave irradiation was developed for the first time. The structures of four pyrazoles compounds were characterized and the interesting intermolecular O-H···N hydrogen bonding was found. Additionally, the crystal packing and hydrogen bonding modes were studied through analysis and calculations.

Summary: The study investigated the use of microwave-assisted sodium hydroxide medium (MWSH) for pre-treatment and saccharification of rice straw to obtain sugar syrup for the production of 5-hydroxymethyl furfural (5-HMF). Optimization of the MWSH pre-treatment achieved a maximum reducing sugar yield of 350 mg/g of treated rice straw (TRS) and a glucose yield of 255 mg/g of TRS. Microwave assisted transformation of sugar syrup with titanium magnetic silica nanoparticle as catalyst achieved a 41.1% yield of 5-HMF. The rice straw based bio-refinery process showed high efficiency in 5-HMF production.

Summary: This study developed lumped reaction schemes to optimize the yields of products from selective hydrogenation of HAH. By studying different reaction schemes and catalysts, rate constants and activation energies were calculated and the effects of water addition on the hydrogenation pathways were explored. The results showed that water addition had significantly different effects on hydrogenation rates and pathways under different catalysts, opening routes for the production of specific products.

Summary: In this study, a polyethyleneimine (PEI)-functionalized polymeric Bronsted acid ionic liquid (PolyE-IL) catalyst was used for fructose dehydration to produce 5-hydroxymethyl furfural (5-HMF) in the presence of isopropyl alcohol (IPA) as a green solvent. Among the tested catalysts, only PolyE-IL with [HSO4](-), [CF3CO2](-), [TfO](-), and [TsO](-) counterions showed the formation of 5-HMF.

Summary: The study investigated the effects of different liquid-liquid flow patterns on the extraction of 5-hydroxymethyl furfural, finding that extraction efficiency varied irregularly with increasing flow rates, and mass transfer rate significantly increased at high flow rates with a trade-off of high-pressure drop. The ethyl acetate/water irregular flow pattern performed the best with high extraction efficiency and mass transfer coefficient, and minimal pressure drop.

Summary: Various multiphase systems consisting of immiscible liquid water, a hydrocarbon, and an ionic liquid were studied for the hydrogenation/hydrolysis of 5-hydroxymethylfurfural. A liquid triphase system composed of water, isooctane, and methyltrioctylammonium chloride achieved excellent selectivity control with high yields of the desired product. By separating the reagents and catalyst in different phases, the catalyst could be effectively recycled and reused multiple times without any loss of activity or selectivity.
