This review discusses the prominent properties of ionic liquid (IL)-based surfactants in adsorption and aggregation, and their versatile applications in various processes, particularly in stabilizing immiscible liquids and solids to produce microemulsions and micelles. The study also investigates their applications in separation processes such as chromatography and extraction techniques, as well as in the petroleum industry for oil recovery and crude oil separation. The importance of selecting or tailoring IL-based surfactants based on operating parameters is emphasized. Challenges and future directions are also discussed.
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.
