摘　　要：设计合成了4个[胆碱][脂肪酸]盐离子液体,并采用红外光谱法对这些离子液体进行了表征。此外,研究了阴离子对[胆碱][脂肪酸]盐溶解纤维素、木聚糖和木质素的影响。利用离子液体对纤维素、木聚糖、木质素溶解性能的差异,实现了对木质素组分的选择性提取,提取率高达61.2%。4 [choline][fatty acid] salt ionic liquid have been synthesized and characterized by infrared spectroscopy. In addition, the influence of anion of [choline][fatty acid] salt on the solubility of cellulose, xylan and lignin was studied. According to the difference of the solubility cellulose, xylan and lignin in ionic liquid, the extraction of lignin fraction was realized,and the extraction rate was up to 61.2 %.
