摘要
由1-甲基咪唑和2-氯乙醇通过微波法合成中间体氯化1-羟乙基-3-甲基咪唑,考察了原料配比、微波功率、加热方式和加热时间对中间体产率的影响。中间体经阴离子交换得到1-羟乙基-3-甲基咪唑四氟硼酸盐离子液体。通过测定中间体的相对分子量分析其纯度,目标产物的结构通过IR1、H-NMR表征。
The key intermediate, 1-butyl-3-methylimidazolium bromide was synthesized effectively from 1-methylim- idazol and 2-chlorthanol under microwave irradiation. The influences of the molar ratio of raw material, microwave power and heating styles and reaction time on the synthetic reaction was also investigated. After an ionic exchange, the ionic liquid 1-hydroxyethyl-3-methyl imidazolium tetrafluoroborate were obtained. The purity of the intermediate was determination by molecular weight with volumetric precipitation method. The structure of the final product were characterized by means of IR, 1HNMR.
