A Simple Regeneration Process Using a CO2‐Switchable‐Polarity Solvent for Cellulose Hydrogels

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
The effect of transformation of the anion chemical structure on cellulose solubility by flowing CO2 gas into aqueous pyrrolidinium hydroxide solutions was investigated. The changes in anion structure allowed for the modulation of cellulose solubility in aqueous pyrrolidinium hydroxide solutions, thus establishing a simple and safe cellulose ...

Xylose Acetals ‐ a New Class of Sustainable Solvents and Their Application in Enzymatic Polycondensation

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
Novel organic solvents with an unmodified carbohydrate core were synthesised both from D‐xylose and directly from biomass and were successfully used as reaction media for lipase biocatalysts to synthesise aliphatic and aromatic polyesters. Abstract The use of organic solvents in academic research and industry applications is facing increasing ...

Functional Group Analysis of Reaction Products from Thermolysis of Lignin in Ethylene Glycol and Diethylene Glycol.

Journal of The Japan Petroleum Institute, 1994
エチレングリコールおよびジエチレングリコール中におけるリグニンの熱分解反応について研究した。反応温度573Kと623Kにおいて3時間反応を行った。ジエチレングリコール中, 反応温度573Kでの反応以外では, 生成物は2液相に分離した。下相はグリコールが主成分で, その他に水溶性の生成物が含まれており, 上相は黒色のオイル状の液体であった。元素分析値, 1H-NMRおよび13C-NMR測定により水素および炭素の分布を定量し, 官能基濃度解析法により生成物中に含まれていると推定される13種類の官能基の濃度を決定した。解析に際して2種類の解析法について検討した: 方法1は解析データとして元素分析値と1H-NMRデータを用いる方法であり, 方法2では元素分析値, 1H-NMRデータのほかに13C ...
