Abstract
The objective of this study is to develop ionic liquids (ILs) derived from organophosphorus acids, featuring thermomorphic phase behavior tailored for homogeneous liquid–liquid extraction applications, addressing the challenges posed by the high viscosity of ILs. The novelty of our work includes a logP-based guideline for designing thermomorphic water/organophosphorus IL solvent systems and a proof-of-concept study on homogeneous liquid–liquid extraction applications. Specifically, we reported a series of novel ILs exhibiting lower critical solution temperature behavior in aqueous solutions by exploring various combinations of tetraalkylammonium cations with organophosphorus acid-based anions. Practical applications utilizing this type of thermomorphic solvent system for extracting metal ions and acids were demonstrated. The benefits of homogeneous extraction, as well as the limitations stemming from the salting-out effect, were presented and discussed.
本研究的目的是开发源自有机磷酸的离子液体(ILs),其特点是为均相液-液萃取应用量身定制的热同构相行为,解决了离子液体高粘度带来的挑战。我们工作的新颖之处包括为设计热同构水/有机磷 IL 溶剂系统提供了基于对数值的指导,并对均相液-液萃取应用进行了概念验证研究。具体来说,我们通过探索四烷基铵阳离子与有机磷酸阴离子的各种组合,报道了一系列新型 IL,它们在水溶液中表现出较低的临界溶液温度。利用这种热形态溶剂系统萃取金属离子和酸的实际应用得到了验证。介绍并讨论了均匀萃取的优点以及盐析效应带来的局限性。
