摘要
以N-甲基咪唑、氯丁烷和氯丙烯为原料,合成了两种离子液体1-丁基-3-甲基氯代咪唑([BMIM]Cl)和1-烯丙基-3-甲基氯代咪唑([AMIM]Cl).用硝酸银滴定法测定其纯度分别为[BMIM]Cl 91.6%,[AMIM]Cl 94.5%;并对两种氯代咪唑离子液体进行了紫外和红外光谱分析.两种离子液体在200～700 nm间都只有一个紫外吸收峰.[AMIM]Cl的λmax=212.0 nm,[BMIM]Cl的λmax=223.0 nm.
Two ionic liquids, 1-butyl-3-methylimidazolium （[BMIM]Cl） and 1-ally-3-methylimidazolium chlorides （[AMIM]Cl）, were prepared from N-methyl imidazole, butyl chloride and allyl chloride. AgNO3 titration showed the purities 91.6% and 94.5% for [BMIM]Cl and [AMIM]Cl, respectively. UV and IR spectra were made for these 2 imidazolium chloride ionic liquids. Both of them had UV absorption peak between 200-700 nmλmax= 212.0 nm for [AMIM]Cl, and λmax=223.0 nm for [BMIM]Cl.
