Abstract: The bronsted acidic ionoic liquid ([HSO3pmim]+[HSO4- ) was synthesized with Nmethylimidazole and 1, 3propyl sulfonic acid lactone. The raw materials and ionoic liquid were characterised by FTIR with KBr, then the absorption peak was analysed serially, the absorption of the chemical bond show that the molecular structure of the product was matched the theoretical structure, so the accurate structure was confirmed. And the reaction conditions of preparation biodiesel from waste cooking oil was optimized, it demonstrated that under the optimum reaction conditions the yield could reach 90.82%, the ionoic liquid could be reused three times. 

摘要: 由1,3丙烷磺内酯和N甲基咪唑通过两步法制备出B酸离子液体[HSO3pmim]+[HSO4-,并采用KBr压片的方法测得原料1,3丙烷磺内酯、N甲基咪唑以及产物的FTIR图谱,逐一分析官能团的吸收峰,得出制备的离子液体和理论[HSO3pmim]+[HSO4-分子结构中的特征吸收峰一一对应,证实了其准确结构,并优化其催化废餐油制备生物柴油的条件,最佳工艺下收率达到90.82%,离子液体可重复利用3次。
