摘　　要：考察了氯化1-烯丙基-3-甲基咪唑([amim]Cl)和1-烯丙基-3-甲基咪唑四氟硼酸盐([amim]BF4)离子液体的微波合成工艺条件,并用红外光谱表征其结构。2种目标产物产率由传统加热下的80.3%和76.2%提高到微波辐射下的86.1%和95.4%,反应时间缩短为传统的1/200和1/67。确定的最佳反应条件为:微波功率均为280W,照射时间分别为125s和105s。The synthesis conditions of 1-Allyl-3-methyimidazolium chloride （[amim]Cl） and 1- allyl-3-methyimidazolium tetrafluoroborate （[amim]BF4） by microwave radiation were investigated and the structures were characterized by IR. The yields of two target products were raised from 80.3% and 76.2% （ under traditional method） to 86.1% and 95.4% （ under microwave irradiation） , and the reaction times were decreased to 1/200 and 1/67 times. The optimal reaction conditions were： microwave power 280 W, the radiation time 125s and 105s respectively.
