Abstract
The imidazolium ionic liquid 1-butyl-3-methylimidazolium bromide(Br) was synthesized from 1-butylbromide and N-methylimidazole under microwave irradiation.At the same time,the factors of setting temperature,microwave power,reaction time and the ratio of row materials were studied on product yield.The results showed that the optimum reaction conditions were:setting temperature 120 ℃,microwave power 400 W,reaction time 15 min,n(N-methylimidazole)∶n(butyl bromide)=1∶1.1,and yield 98.81 %.The structure of the product was characterized by IR,1H-NMR.The moisture absorption and solubility of 1-butyl-3-methylimidazolium bromide were tested.
