Design of Amino Acid ILs for Dissolution of Lignocellulosic Biomass
Cellulose consists of linear glucose polymer chains that form a very tight hydrogen-bonded supramolecular structure, and the multiple hydrogen bond among the cellulose molecules results in the formation of highly ordered crystalline regions . Hence, cellulose does not dissolve in water and common organic solvents under ambient conditions. Since chemical or enzymatic reactions are generally conducted in solution, extensive studies for the development of cellulose dissolving liquids have been attempted. However, there are limited examples of such solvent systems, and they all require large quantities of hazardous chemicals and high temperatures . Therefore, development of more safe and efficient cellulose dissolution liquids is needed from the standpoint of green chemistry .
Ionic liquids (ILs) are molten salts that melt below 100 °C  and have many unique chemical and physical properties. They are attractive alternatives to organic solvents due to their high...
