Synthesis of Banana Oil through Esterification Reaction Catalyzed by Proton Supported Ionic Liquids——Experimental Teaching Application of Recyclable Solid Catalysts
Esterification reaction is an important training project in university organic synthesis experimental courses.In this experiment,N-methylimidazole bisulfate supported ionic liquid catalyst was prepared by sol-gel method(Meim-HSO4@SiO2),Meim-HSO4@SiO2 can re-place traditional inorganic acids in catalyzing the esterification reaction of acetic acid and isoamyl alcohol.Compared to before improvement,solid-state catalysts Meim-HSO4@SiO2 more convenient to use,with a conversion rate increase of about 22.1％.After the reaction is comple-ted,catalyst recovery and reuse can be achieved simply by filtration,washing,and drying.Under the premise of optimizing teaching quality,costs are expected to be reduced by about 37.5％.This experiment provides a practical and feasible new approach for catalyst selection in the u-niversity chemistry teaching experiment"Preparation and Identification of Banana Oil",which meets the development needs of green chemistry.This project contributes to the improvement of students'comprehensive abilities and the cultivation of improved thinking.
