摘要:采用亲水性离子液体［BMIM］Cl取代传统微乳液中的水相，按m(表面活性剂CTAB)∶m(［BMIM］Cl)∶m(环己烷)∶m(正丁醇)=1∶10∶（1~6）∶（4~10）配制出新型离子液体（ILs）微乳液，并对其热稳定性、电导性及其对马尾松的渗透性能进行分析。结果表明，O/ILs型微乳液在70℃、400 min的条件下对马尾松木条的饱和渗透率可达到121%，明显高于其他传统型微乳液。浸渍渗透的同时可降解溶出少量纤维素或半纤维素，打开纹孔内部通道，底物表面变得粗糙并产生褶皱，马尾松木条内部比表面积增大，利于后续药品的渗入和反应。

Abstract:The preparation of a new type microemulsion in which the aqueous phase was displaced by hydrophilic ［BMIM］Cl was introduced, the mass ratio of surfactant CTAB∶［BMIM］Cl∶cyclohexane∶n-butyl alcohol wass 1∶10∶（1~6）∶（4~10）in the micromulsion. The micromulsion was characterized by its conductivity and thermostability. Some primary research on its permeability in to masson pine was carried out. The result showed that the saturated percolation quantity of O/ILs microemulsion in material could reach to 121% in the condition of 70℃，400 min, which was obviously higher than the other converitional microemulsion. SEM observation showed that the inner passage of pit was open because of partly dissolution of cellulose, the porosity and specific surface area of lignocelluloses were increased significantly which was helpful to the subsequent permeation and reaction of the chamicals.
