Abstract
A Deep Eutectic Solvent (DES) system that comprises betaine monohydrate as one component. Additional component can be urea or acids, such as malonic acid or dtric add. The melting point of the mixture can be considerably lower 5 than the melting point of either component. The use of betaine monohydrate is advantageous because of its low cost, among other reasons. The DES can be used to dissolve components, such as cellulose, starch, lignin, synthetic polymers, and others, that are not soluble in other media. After treatment of AVICEL (cellulose) with a DES comprising betaine monohydrate and urea, there can be a decrease of crystallinity of at least about 10-15 %.
