研究了碱强化的离子液体微乳液（ DILMS ）体系的配比、浸渍方式及处理条件对速生阔叶材桉木酶解效率的影响，探讨了浸渍处理后原料残渣和浸渍液中单糖含量的变化，并利用离子色谱法对单位质量底物的葡萄糖增加比进行定量分析．实验结果表明：适宜的DILMS浸渍工艺参数为100℃、8 h、底物目数40（即直径180～380μm），进一步结合碱强化的乙二胺浸渍工序（70℃，3 h）而形成的“两步法”预浸渍可以使单位质量底物中葡萄糖占总还原糖的百分比由64．33％上升到96．34％，酶解得率由35．8％上升到83．2％，葡萄糖实际产量提高了1．11倍．研究表明碱强化的离子液体微乳液具有优良的预浸渍处理效果．

The effects of the composition , impregnation mode and treatment condition of alkali-strengthened DILMS ( Double Ionic Liquid Microemulsion ) on the enzymatic hydrolysis efficiency of eucalyptus were discussed , and the variation of monose content in the residue and the impregnation liquid was analyzed .Moreover , the increment of glucose in the enzymatic hydrolysis process was quantitatively investigated by means of the ion chromatography .Fi-nally, suitable DILMS impregnation conditions , that is, a temperature of 100℃, an impregnation duration of 8 h and a substrate size of 40 meshes ( namely a diameter of 180~380μm) , were determined .Experimental results in-dicate that, by using the alkali-strengthened quadrol (70℃, 3 h) impregnation with the DILMS preimpregnation , the glucose proportion in the total reducing sugar increases from 64.33%to 96.34%, the enzymatic hydrolysis effi-ciency improves from 35.8%to 83.2%, the actual yield of glucose is 2.11 times that of the untreated raw mate-rial.It is thus concluded that the alkali-strengthened DILMS is effective in improving the preimpregnation efficiency .
