However, the cross-linked PILs’ solute absorption capacity and selectivity for butanol relative to water were below the levels likely needed for a viable extractive fermentation process. Uncross-linked PILs bearing long-chainaliphatic substituents also proved to be biocompatible by virtue of their insolubility in water, and delivered significantly improved absorptive performance. Among biocompatible absorbents
hydrophobic alkyl chains as the building blocks, followed by ion exchange with Keggin-type phosphotungsticacid (PW). The obtained hybrids POSS–ILx–PW were demonstrated to be mesostructured and amphiphilic materials with good thermalstability. Catalytic tests for the H2O2-based epoxidation of cyclooctene have shown that these newly designed catalysts exhibit extraordinary catalyticactivities, catalytic
使用多面体低聚乙烯基硅倍半氧烷(POSS)和带有疏水性烷基链的离子液体(IL)作为构建基,然后与Keggin型磷钨酸(PW)进行离子交换,成功合成了一系列新型的基于多金属氧酸盐(POM)的稳定聚合物杂化物)。所获得的杂种POSS–IL x –PW被证明是介观结构和两亲材料,具有良好的热稳定性。H 2 O 2的催化测试环辛烯的环氧基氧化表明,这些新设计的催化剂表现出非凡的催化活性,催化速率和相当稳定的可重复使用性。揭示了独特的两亲性和介孔结构是造成催化剂在与H 2 O 2的环氧化反应中优异性能的原因。

vinylimidazolium-typed poly(ionic liquid) (PIL) latexes and nanoparticles via dispersionpolymerization of ionic liquid monomers in aqueous solutions. A homologous series of vinylimidazolium-typed ionic liquid monomers with different alkyl tail length (C8−C18) were synthesized via quaternization of 1-vinylimidazole with corresponding n-alkyl bromides. Dispersionpolymerization of these monomers was conducted
在这项贡献中,我们报告了通过离子液体单体在水溶液中的分散聚合反应,可以轻松制备乙烯基咪唑型的聚(离子液体)(PIL)胶乳和纳米颗粒。通过1-乙烯基咪唑与相应n的季铵化反应,合成了具有不同烷基尾长(C8-C18)的乙烯基咪唑鎓型离子液体单体的同源系列-烷基溴化物。这些单体的分散聚合反应是在70°C的水溶液中,以50 g / L的单体浓度进行的,而无需添加其他稳定剂。对于具有足够长的烷基链(≥C12)的离子液体单体,发现了直径为20-40 nm的PILs纳米颗粒,它们在水性介质中是自稳定的。在相同的步骤中,在10 mol%的基于二乙烯基咪唑基的交联剂的存在下进行交联的PIL纳米颗粒的制备。与双(三氟甲基磺酰基)酰亚胺锂进行阴离子交换后,合成后的交联PIL纳米颗粒可以转移到有机溶剂中,例如极性DMF和非极性甲苯。这种分散聚合不需要分散剂,并有可能在水溶液和有机溶液中大规模合成PIL纳米粒子。预期
