摘要
在微波辅助下合成、纯化了离子液体溴化1-甲基-3-丁基咪唑[BMIM]Br,测定了产率和纯度,并使用FTIR和~1HNMR进行了产物结构表征;以[BMIM]Br为萃取剂对催化裂化和加氢裂化柴油进行超声辅助萃取脱硫,并测定了脱硫率;在反应条件优化、测试方法优化、脱硫选择性等方面设置了多个开放性设计实验。该实验项目融合精细化工和石油化工方向,在促进学生知识体系跨界,全面训练综合实验技能,培养学生解决实际问题能力以及科研能力形成等方面作用明显;实验项目以模块化设置,符合"绿色实验"原则。
Ionic liquid 1-methyl-3-butylimidazole bromide[BMIM]Br was synthesized and purified under microwave-assisted.The yield and purity of the product were determined.The structure of the product was characterized by FTIR and^1HNMR.Ultrasonic-assisted extraction desulfurization of FCC and hydrocracking diesel oil with[BMIM]Br as extractant was carried out and the desulfurization rate was determined.A number of open designing experiments have been set up to optimize the reaction conditions,test methods,desulfurization selectivity and so on.The experiment combines fine chemical and petrochemical specialties and is offered as a senior specialty experiment.For students,it plays an obvious role in promoting knowledge system to cross-border and omni-directional training of comprehensive experimental skills,cultivating ability to solve practical problems,innovative consciousness and scientific research ability formation.The experimental projects were designed with modularized method,according with the principles of green experiment.
