Phosphonium and Ammonium Ionic Liquids with Aromatic Anions: Synthesis, Properties, and Platinum Extraction
摘要:
以三(丙烯酰甲基)氯化铵(Aliquat 336)和三己基(十四烷基)氯化磷(Cyphos IL101)为前体,采用偏合成路线制备了几种具有官能化芳香阴离子的疏水性长链季铵和鏻离子液体(IL)。加入具有羟基、甲氧基、硫醇和硫醚官能团的芳香族阴离子以及四苯基硼酸阴离子后,IL 的化学稳定性得到了提高,其物理化学性质也发生了改变。此外,芳香族阴离子会明显降低铵基和鏻基 IL 的水溶性和吸水性。利用液相微萃取技术,硫醇基和硫醚基 ILs 被用于从水相萃取铂。与时间相关的研究表明,30 分钟后,铂的去除率可达 95%。阴离子在水介质中的浸出率为 0.01 wt-%,因此发现所评估的 ILs 适合用作从水溶液中萃取铂的萃取剂。

The present invention relates to microemulsions of immiscible fluids stabilized by reactive ionic liquid surfactant wherein the ionic liquid surfactant has a melting point less than 80° C. The invention also relates to composite materials comprising a copolymer of ethylenically reactive species, wherein one of the species is a reactive ionic liquid surfactant having a melting point less than 80° C., and wherein the material also comprises non-reactive Class I fluid. The invention further relates to methods for synthesizing the composite materials comprising preparing a microemulsion of immiscible Class I fluid and Class II fluid stabilized by reactive ionic liquid surfactant wherein the ionic liquid surfactant has a melting point less than 80° C., and polymerizing the microemulsion to form a composite material.
Die Erfindung betrifft die Entschäumung von ionischen Flüssigkeiten sowie Zusammensetzungen enthaltend mindestens eine ionische Flüssigkeit und mindestens einen Entschäumer und gegebenenfalls ein Lösungsmittel und/oder weitere sonstige Hilfs- oder Zusatzstoffe.
