摘要/Abstract

摘要： 合成了14种具有代表性的离子液体，从中筛选了具有较好秸秆溶解能力和环境友好特性的室温离子液[Meim]DMP。该离子液体可以高效处理秸秆，并且可以进行原位酶解糖化，比未处理秸秆的糖化率提高了2.4倍，实现了天然纤维素材料利用的绿色转化工艺。而且，经过原位酶解之后离子液体[Meim]DMP可以有效地回收使用，重复使用5次后仍然保持很好的性能。

Abstract: 14 representative ionic liquids（ILs）were synthesized，from which [Meim]DEP was chosen as an environment-friendly solvent for in situ enzymatic saccharification in view of its biocompatibility with both lignocellulose solubility and enzyme activity. With the implementation of corn stover pretreatment in [Meim]DEP，the enzymatic saccharification rate was directly enhanced to 2.4-fold and in situ enzymatic saccharification was realized. Furthermore，[Meim]DMP can be efficiently recovered and reused after the in situ enzymatic saccharification. The IL could keep good pretreatment characteristics after 5 times recycle.
