具有木质素溶解能力的离子液体的合成

摘要

Ionic liquid [ BMIM ] [ CH3 CO0 ] are prepared with strong basic anion - exchang resins, it is charaterized by HNMR spectrum. Using it to dissolution lignin in corn stalk, calculate the lignin dissolu- tion an finally we found,the ionic liquid [ BMIM] [ CH3COO] has good dissolubility of lignin.%利用强碱型阴离子交换树脂合成了一种离子液体[BMIM][CH3COO]，并通过HNMR图谱对其进行了表征。然后利用其溶解玉米秸秆中的木质素，通过木质素溶出率的计算可知：合成的离子液体[BMIM][CH3COO]对木质素有着良好的溶解能力。
