摘要:
由于具有液程宽、蒸汽压低、溶解能力强、电导率高等独特性能,磁性离子液体近年来受到越来越多的关注。采用两步合成法合成磁性离子液体[C4mim]FeCl4、[C4mim]FeBrCl3,通过红外光谱、拉曼光谱、核磁共振氢谱对其结构进行表征,并对其磁性、密度及对可挥发性有机气体丙酮、乙醇的吸附特性进行了研究。研究结果表明:[C4mim]FeBrCl3的密度较[C4mim]FeCl4大,室温下2种磁性离子液体均为顺磁性物质,其磁化率随外加磁场强度的增强呈线性增加,其密度随温度的升高线性下降;2种磁性离子液体对丙酮气体有较显著吸收,而对乙醇气体吸收效果不显著。

Abstract:
Because of its wide liquid range, low vapor pressure, excellent solubility and high ionic conductivity, magnetic ionic liquid has attracted more and more attention in recent years. Two kinds of magnetic ionic liquid,[C4mim] FeCl4 and[C4mim] FeBrCl3, were synthesized via a simple two-step method. Magnetic ILs were characterized by FT-IR, 1H NMR and Raman.In addition, magnetic properties, density, and adsorption properties of volatile organic gases as acetone, ethanol were studied. The study finds that magnetic ionic liquid[C4mim] FeBrCl3 has larger density than[C4mim] FeCl4. The densities of these two magnetic ILs has a linearly downward trend with increasing temperature; two magnetic ionic liquids at room temperature are paramagnetic; acetone exhaust emissions can be sbsorbed remarkablly, while these two MILs have little absorption of ethanol.
