“…Nanosize materials, on the other hand, have been found with excellent thermophysical and surface/interface properties. , Based on this and in the continuation of our previous works on using ILs in desulfurization of fuels , as well as in IFT reduction of organic/water systems, − an attempt was made here to use a novel nano gemini IL in reducing the IFT of crude oil/water. The molecule of the used IL has a four methylene spacer group and eight carbons in the alkyl chain, namely 1,1′-(butane-1,4-diyl)bis(3-octyl-1 H -imidazol-3-ium) bromide and briefly denoted as [C 8 -4-C 8 im]Br 2 (Figure ).…”

Gemini ionic liquids (ILs) are usually known to have significant surfactant behavior. Nanomaterials, on the other hand, are capable of improving interface properties. The current study explores the use of a novel nano gemini imidazolium IL with a molecular structure of a four methylene group spacer for reducing crude oil/water interfacial tension (IFT). The gemini IL was prepared purely by a two-step synthesis method and characterized in different ways. Results revealed that IFT was drastically decreased to 97.8% in the presence of the IL and more decrease was achieved with temperature and pH variations. The high performance of the IL can be attributed to the strong IL amphiphilic nature. The salt effects in the presence of the IL were evaluated with NaCl, MgCl2, and their mixture. Results revealed more IFT reduction under salinity conditions because of a remarkable found synergism effect, unlike conventional surfactants. The findings encourage the use of seawater IL solutions in chemical enhanced oil recovery. The obtained salt-free IFT data were precisely reproduced with the well-known Frumkin adsorption isotherm, and the corresponding thermodynamic parameters were obtained at different temperatures. From thermodynamic results, a spontaneous IL adsorption was deduced.

“…Recent investigations demonstrated that the presence of nanoparticles with ionic liquids or other demulsifiers in a system could enhance the interfacial properties and the demulsification process. The enhancement may be because demulsifier molecules adsorb on the surface of nanoparticles and create large particles which push them to move towards the O-W interface and break the interfacial film [ 153 , 154 ]. Another method was reported to coat ionic liquids onto the surface of nanoparticles to achieve promising results [ 155 , 156 ].…”

In recent years, ionic liquids have received increasing interests as an effective demulsifier due to their characteristics of non-flammability, thermal stability, recyclability, and low vapor pressure. In this study, emulsion formation and types, chemical demulsification system, the application of ionic liquids as a chemical demulsifier, and key factors affecting their performance were comprehensively reviewed. Future challenges and opportunities of ionic liquids application for chemical demulsification were also discussed. The review indicted that the demulsification performance was affected by the type, molecular weight, and concentration of ionic liquids. Moreover, other factors, including the salinity of aqueous phase, temperature, and oil types, could affect the demulsification process. It can be concluded that ionic liquids can be used as a suitable substitute for commercial demulsifiers, but future efforts should be required to develop non-toxic and less expensive ionic liquids with low viscosity, and the demulsification efficiency could be improved through the application of ionic liquids with other methods such as organic solvents.

“…Since ILs have strong adsorption capabilities, the surface on the carbon quantum dots was protected against friction, which then improved their stability efficiency in tribological evaluations. Saien and Hashemi [84] used 1-hexadecyl-3-methyl imidazolium chloride IL as a surfactant to study its interaction with Fe 3 O 4 nanoparticles in a biphasic oil/water system. In a study by Okoli et al [85] it was found that the sole use of ILs without additional co-surfactants is capable of producing good quality (monodispersity with narrow size distribution) metal alloy nanoparticles which display enhanced catalytic activities.…”

For over a decade, ionic liquids (ILs) have attracted enormous attention from scientists across the globe. The history of these compounds traces back to 1914 where the inception of the first IL with a melting point of 12°C was made. Years later, a progression of the remarkable related compounds have been discovered. Out of many analogous compounds realized from time to time, the imidazolium class of ionic liquid is the most studied because of their air and moisture stability. The physicochemical properties of ILs differ significantly depending on the anionic/cationic species and alkyl chain length. ILs have found application in many scientific fields the most recent being good solvents and stabilizing agents in the nanomaterial synthesis. Studies have showed that ILs not only stabilize as synthesized nanomaterials but also provide environmentally green routes towards nanomaterials engineering.
