  磁性离子液体1-烷基-3-甲基咪唑四氯高铁酸盐与乙酸乙酯的二元混合物的密度和粘度在（293.15至323.15）K的温度下

  摘要：

  磁性离子液体（MIL）的二元混合物的物理化学性质对其应用的工业过程设计至关重要。在这项工作中，合成并表征了三个MIL，包括1-丁基-3-甲基咪唑四氯高铁酸盐（[Bmim] [FeCl 4 ]），1-己基-3-甲基咪唑四氯高铁酸盐（[Hmim] [FeCl 4 ]）和1-辛基-3-甲基咪唑鎓四氯高铁酸盐（[Omim] [FeCl 4]）。在温度（293.15至323.15）K下，以5 K的间隔在整个组合物范围内测定这些MIL与乙酸乙酯（EA）的二元混合物的密度和粘度。密度随温度变化的数据与线性方程拟合，粘度与Vogel–Fucher–Tammann（VFT）方程相关。结果表明，随着IL浓度的降低和温度的升高，二元混合物的密度和粘度显着降低。计算了过量的摩尔体积（V E）和粘度偏差（Δη），并与Redlich-Kister方程很好地拟合。负V E和Δη 在整个组成范围内，表明MIL和EA之间的

  In this work, 16 kinds of [FeCl4]--based magnetic ionic liquids (ILs) with different cation structures have been designed and synthesized, and their structures are characterized by IR and Raman spectroscopy. Then the lower critical solution temperature (LCST)-type phase behavior of these magnetic ILs in water is investigated as a function of concentration. It is shown that cation structure, alkyl chain length and molar ratio of FeCl3/chloride IL have a significant influence on the LCST of the mixtures. The phase separation temperature can be tuned efficiently by these factors. Meanwhile, the LCST-type phase separation process is also investigated by dynamic light scattering. The results support the mechanism that the hydrogen bonds of the [FeCl4]- anion with water have been gradually disrupted to form ILs aggregates with increasing temperature. In addition, the stability of the ILs in water is also examined in some details. These LCST-type phase separation systems may have potential applications in extraction and separation techniques at room temperature.

  本研究设计并合成了 16 种具有不同阳离子结构的[FeCl4]基磁性离子液体（ILs），并利用红外光谱和拉曼光谱对其结构进行了表征。然后研究了这些磁性离子液体在水中的低临界溶液温度（LCST）型相行为与浓度的函数关系。结果表明，阳离子结构、烷基链长度和 FeCl3/chloride IL 的摩尔比对混合物的 LCST 有显著影响。相分离温度可通过这些因素进行有效调节。同时，还利用动态光散射对 LCST 型相分离过程进行了研究。结果支持[FeCl4]-阴离子与水的氢键随着温度升高而逐渐断裂形成 ILs 聚集体的机理。此外，还详细研究了 ILs 在水中的稳定性。这些 LCST 型相分离系统可能会在室温下的萃取和分离技术中得到潜在应用。

  The exploitation of dual functional magnetic and acidic ionic liquids (MAILs) for hydrolysis of cellulose to platform chemicals can solve some practical challenges through easy separation of products and efficient catalyst recyclability. In this work, seven C(n)mim/FeCl4 MAILs were synthesized and investigated with combined experimental and molecular dynamics. The MAILS contained FeCl4- anions and exhibited a typical hard magnetic materials behavior with rather strong magnetic susceptibilities. These MAILS were stable up to 250-310 degrees C, the decomposition was started up at 250/310-480-810 degrees C in two steps with the formation of the undecomposed residue. The Gibbs energy for the reaction of glucose/xylose conversion to 5-hydroxymethylfurfural by metal chlorides in the C(n)mimCl ionic liquid was studied using the density functional theory calculations and the results that C(3)mim/WCl3 may be the most hopeful catalyst. The MAILs have the potential to open up promising new catalytic systems because of their easy product separation and efficient catalyst recyclability. (C) 2014 Elsevier Ltd. All rights reserved.
