5-Hydroxymethylfurfural (5-HMF) is a versatile bio-platform chem. that connects biomass to a variety of different fuels, chems., and materials. In this work, novel Bronsted acid-based deep eutectic solvents (DESs) with both solvent and catalytic functionalities for glucose dehydration into 5-HMF were developed without the need of addnl. metal salt catalysts or heterogeneous catalysts. The types of hydrogen bond donor (HBD) and hydrogen bond acceptor (HBA), the ratio of HBD to HBA of the DES, heating time, reaction temperature, initial glucose concentration, and moisture content of the DES were systematically investigated to reveal the interplay of the DES in the conversion of glucose to 5-HMF. The most effective DES was found to be tri-Et benzyl ammonium chloride (TEBAC)/formic acid (FA) (molar ratio: 2:1) with a 5-HMF yield of 30.5 ± 1.0% in glucose dehydration and approx. 100% glucose conversion (initial glucose concentration: 2.5 weight %) in 60 min at 150°C. Most importantly, after five cycles, the TEBAC/FA (1:2) DES retained high stability and catalytic activity, with the yield of 5-HMF remaining 30.1 ± 0.5%. Interestingly, as the water content of the DES increased to 70%, the 5-HMF yield increased to 36.5 ± 1.0% along with an 8.01 ± 1.4% yield of levulinic acid. The finding of this study provided insights into the TEBAC/FA (1:2) DES with dual capabilities that might support more efficient bio-based commodity chem. production methods. This study involved multiple reactions and reactants, such as N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3Recommanded Product: N-Methyl-N,N-dioctyloctan-1-aminium chloride).
N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3) belongs to organic chlorides. Chlorination modifies the physical properties of hydrocarbons in several ways. These compounds are typically denser than water due to the higher atomic weight of chlorine versus hydrogen.While alkyl bromides and iodides are more reactive, alkyl chlorides tend to be less expensive and more readily available. Alkyl chlorides readily undergo attack by nucleophiles.Recommanded Product: N-Methyl-N,N-dioctyloctan-1-aminium chloride
