properties are discussed. The [AlBr4]−based salts are—with one exception—solid at room temperature, while the compounds based on the anion [Al2Br7]− are liquid at room temperature. The liquid salts show low viscosities (49–139 mPa s), medium to high conductivities (0.76–3.53 mS cm−1) and high densities (1.82–2.04 g cm−3) at 28 °C. Furthermore, we showed aluminum electrodeposition from Lewis acidic ILs based
合成了十二种基于溴铝酸盐的离子液体(IL),并通过IR,拉曼光谱和NMR光谱以及部分单晶X射线衍射对其进行了表征。确定了它们的主要理化性质,包括熔点,电导率,粘度和密度,并与相关的离子液体进行了比较。讨论了阳离子和阴离子对理化性质的影响。基于[AlBr 4 ] -的盐在室温下为固体,其中一个例外为基于阴离子[Al 2 Br 7 ] -的化合物在室温下为液体。液态盐的粘度低(49–139 mPa s),电导率中等至高(0.76–3.53 mS cm -1)和28°C时的高密度(1.82-2.04 g cm -3)。此外,我们显示了基于AlBr 3和1-己基-3-甲基咪唑鎓溴化物的Lewis酸性ILs的铝电沉积,并研究了各种配方的稳定性范围。
Size Matters! On the Way to Ionic Liquid Systems without Ion Pairing
Several, partly new, ionicliquids (ILs) containing imidazolium and ammonium cations as well as the medium‐sized [NTf2]− (0.230 nm3; Tf=CF3SO3−) and the large [Al(hfip)4]− (0.581 nm3; hfip=OC(H)(CF3)2) anions were synthesized and characterized. Their temperature‐dependent viscosities and conductivities between 25 and 80 °C showed typical Vogel–Fulcher–Tammann (VFT) behavior. Ion‐specific self‐diffusion

Two new ionic plastic crystals of [NEtMe2Pr][BEt3Me] and [NEt2MePr][BEt3Me] were found. In contrast, the highest-temperature solid-phase of [NEtMe2Bu][BEt3Me] and [NEt2MeBu][BEt3Me] were assigned t...

Ein Verfahren zur Herstellung von Pentaerythritestern von Phosphorigsäurederivaten durch Umsetzung von Pentaerythrit mit einem Phosphortrihalogenid und einem Phenol in Gegenwart eines quaternären Salzes oder eines Polyethers wird beschrieben.
Durch die Anwendung solcher Katalysatoren kann nicht nur die Ausbeute verbessert, aber, durch den Einsatz des Phenols zu Beginn der Umsetzung vom Pentaerythrit mit dem Phosphortrihalogenid auch das ganze Verfahren in einer Stufe durchgeführt werden.
