Abstract 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.
