摘　　要：构建了一种全新的专业设计型实验体系:双阳离子液体的制备及萃取分离甲苯-正庚烷共沸体系。合成并表征新型“绿色溶剂”双阳离子液体;以双阳离子液体作为萃取剂,测定其对甲苯-正庚烷共沸体系的分离能力并进行相图绘制。通过该综合实验教学,既促进学生对多学科基础知识的掌握,又能激发学生科研探索兴趣,培养其绿色化学意识与理念。The experiment combines modern research frontier hotspots and builds a brand-new professional design experimental system:preparation of dicationic ionic liquids(DILs)and separation of toluene-n-heptane azeotropic system.A new“green solvent”DIL was synthesized and characterized.The separation ability of toluene-n-heptane azeotropic system was determined.Finally,ternary diagram was performed.The comprehensive experimental teaching not only integrates students’mastery of multidisciplinary basic knowledge,but also stimulates their interest in scientific research,and cultivates their awareness and concept of green chemistry.
