采用简单、绿色的化学方法制备了一系列以胆碱为阳离子、氨基酸为阴离子的室温离子液体，并对其进行了表征。大多数白介素有效且选择性地溶解木质素（每g白介素的木质素溶解度为140 ~ 220 mg）。木聚糖在这些离子中的溶解度（范围从<1到85 mg g - 1）取决于阴离子的性质，而纤维素几乎不溶（<5 mg g - 1）。此外，经IL预处理后，微晶纤维素和稻草的酶解能力显著增强[Ch][Gly]。
A series of room temperature ionic liquids (ILs), in which cholinium acts as the cation and amino acids as the anions, were prepared via a simple and green chemical route, and characterized. Most of the ILs dissolved lignin efficiently and selectively (with solubilities of 140–220 mg of lignin per g of IL). The solubility of xylan in these ILs (which ranged from <1 to 85 mg g−1) depended on the nature of the anion, while cellulose was scarcely soluble (<5 mg g−1). In addition, enzymatic hydrolysis of microcrystalline cellulose and rice straw was enhanced significantly after pretreatment using the IL [Ch][Gly].
