在未经改装的家用微波炉中,利用微波间歇辐射的方法,几分钟内制备出多种离子液体。反应时间分别为:[Emim]Br4.5min、[Bmim]Br4.0min、[Emim]BF4 3.5min。结果表明微波加热可显著提高合成速率。[Emim]BF4离子液体的结构经红外光谱验证。
Using microwave intermittence radiation method, prepared several ionic liquids in the microwave ovens without convertion in several minutes. The reaction time was [ Emim] Br 4.5min, [ Bmim] Br 4.0min, [ Emim] BF4 3.5min,respectively. The result indicated that the microwave heating obviously enhaned the synthesis speed. The structure of the [ Emim ] BF4 ionic liquids had been proved by IR.
