“…Takahashi et al found that a 0.05 M 1-(1-butylsulfonic)-3-methylimidazolium hydrogen sulfate ([Sbmim][HSO 4 ]) solution was sufficiently low to allow for the growth of E. coli. In the diluted ILs, glucose yield of 48% was obtained from the hydrolysis of bagasse at 190 C (Kuroda et al, 2017). The efficient isolation of generated reducing sugar in ILs and the compatibility between microorganism and ILs remain to be fully investigated.…”

In biomass refinery, ionic liquids (ILs) enable more efficient conversion and higher product selectivity at milder conditions compared with conventional molecular solvents. Carbohydrates and lignin are the dominating components in biomass. The aim of this article is to update the recent progresses of ionic liquids‐based catalytic systems for lignocellulosic biomass conversions based on the published works mostly in the last 5 years. Mechanistic understanding of the catalytic processes in converting biomass to renewable chemicals and fuels is critically important for the design of superior catalysts. Apart from theoretical approaches, two recently developed characterization techniques, in situ far infrared spectroscopy and two‐dimensional nuclear magnetic resonance have been applied in the molecular level understanding of both catalysts and catalyzed reactions during biomass conversions in ILs. The major challenges and opportunities involved in the large‐scale production of biomass platform chemicals are also discussed. This article is categorized under: Bioenergy > Science and Materials

Solvated Structure of Cellulose in a Phosphonate-Based Ionic Liquid

We investigated the solvated structure of cellulose in a phosphonate-based ionic liquid (IL) solution utilizing scattering experiments and all-atom molecular dynamics (MD) simulations. Based on the high-energy Xray total scattering experiment and MD simulations, a predominant interaction between cellulose and the IL was established, i.e., hydrogen bonding between the IL anion species and hydroxyl groups of cellulose. In addition, it was found that intramolecular hydrogen bonds existed within cellulose molecules, even when dissolved in the IL. Furthermore, the conformation of cellulose chains in the IL was investigated by a small-angle X-ray scattering experiment. As a result, it was found that cellulose molecules were dispersed at the molecular level and existed as rigid-rod-like polymers because of the intramolecular hydrogen bonds within the cellulose molecules. In dynamic light scattering experiments, a speckle pattern was observed for concentrated cellulose solutions. This indicated the existence of a physical-gel-like frozen inhomogeneity.
