ABSTRACT

Ionic liquid (IL)-based surfactants exhibit prominent properties in adsorption and aggregation, providing strong influence on interfacial properties of phases. This review overviews the main characteristics of IL-based surfactants and their versatility in different processes particularly those dealing with the stabilization of immiscible liquids and solids for the aim of producing microemulsions and micelles. Applications in separation processes for chromatographic and extraction techniques and in the petroleum industry for augmenting the oil recovery, separation of asphaltene and paraffin deposits and crude oil separation are precisely studied by describing the mechanisms as well as qualitative and quantitative comparison to conventional surfactants everywhere relevant. These are particularly highlighted with respect to the importance of selecting/tailoring the desired IL-based surfactants in relation to the influence of operating parameters. Moreover, challenges and directions of the future outlooks on specific topics are discussed.

摘要

离子液体（IL）基表面活性剂在吸附和聚集方面表现出突出的特性，对相的界面特性产生强烈影响。本综述概述了基于 IL 的表面活性剂的主要特性及其在不同工艺中的多功能性，特别是那些涉及稳定不混溶液体和固体以生产微乳液和胶束的工艺。通过描述机理以及与所有相关的常规表面活性剂的定性和定量比较，精确研究了色谱和萃取技术的分离过程以及石油工业中用于提高采收率、沥青质和石蜡沉积物的分离以及原油分离的应用。这些特别强调了根据操作参数的影响选择/定制所需的基于 IL 的表面活性剂的重要性。此外，还讨论了特定主题的挑战和未来展望的方向。
