“…The same trend has been observed in the literature reporting on surfactants instead of ILs. 21,33 In the current study, interfacial tension between crude oil and water is observed to be 36.26 ± 0.01 mN/m at 288.15 K. The obtained results exposed very interesting behavior for the 1,3-dialkyl imidazolium family of ILs. On comparing the IFT of ILs with eightc a r b o n , e .…”

Enhanced oil recovery is governed primarily by the role of interfacial tension between crude oil and water. Interfacial tension (IFT) of the crude oil−water system is one of the vital factors in the analysis of the capillary forces affecting trapped oil within the reservoir rocks. High salinity and temperature of the reservoirs tend to make researchers search for new surfactants to lower the interfacial tension in crude oil−water systems. The current study hopes to create a move toward solving the above problem through the use of aromatic ionic liquids (ILs) based on imidazolium as the cation and various anions such as [HSO 4 ] − , and [PF 6 ] − in different concentrations. This work involves the study of the effect of concentration, temperature, time, and brine on the fate of surface tension (SFT) of water and interfacial tension of crude oil− water systems. The present study also addresses the trend in the electrical conductivity of ILs in water along with the effect of temperature and concentration of ILs. The study reveals that these ILs are effective in reducing the SFT and IFT of water and crude oil−water systems at high salinity and temperature conditions. In the IFT measurements, a linear decrement with increase in temperature is observed for crude oil−water in the presence of ILs. The interfacial tension of the various imidazolium-based ionic liquids with the crude oil−water system has been measured as a function of temperature by means of the Wilhelmy plate method. The influence of the nature of cation and anion of ionic liquids and of the chain length on the cationic head of the ILs on interfacial tension is also discussed in detail. At increased salinity conditions, unlike classical surfactants, these ILs are found to be more successful. Enhanced efficiency of the drop in IFT using NaCl and IL mixture has been confirmed by measuring the IFT between crude oil and the aqueous solution of IL. The synergism of salt and IL mixture on the reduction of IFT has been observed.

“…Therefore, the rise of temperature can shorten the time to reach the equilibrium and further decrease the equilibrium interfacial tension compared the results of 50°C with 60°C. The phenomena were also found when we studied the interfacial tension between gemini surfactant solution of 14-4-14 or 16-4-16 and crude oil from Shengli oil field [13]. The reason is that the increase in temperature will affect the mutual solubility of the solvents, the CMC of the surfactants, the adsorption kinetics of the surfactants molecules, and the distribution of the surfactants between the oil and water, etc, so as to affect the dynamic and equilibrium interfacial tensions.…”

“…Many factors will affect the adsorption of the surfactant onto an oil-water interface and leads to variations in interfacial tension between the oil and surfactant solution, such as the nature of surfactant and oil, ionic strength of the solution, temperature [13], and so on. In this study, we primarily investigated the effects of the length of the alkyl chain and the spacer group of the gemini surfactants, temperature, salt and polymer on the interfacial tension between crude oil and the surfactant solution.…”

The effects of the hydrocarbon chains and spacer groups of gemini surfactants, salt, temperature, and polymer on the interfacial tension of crude oil-water mixtures were investigated in this paper. The length of the alkyl chain is a major factor affecting the properties of a gemini surfactant, and the spacer group is also an important factor influencing the surfactant properties. The addition of salt results in a great decrease in the CMC and favors the reduction of interfacial tension, which shows that a gemini surfactant has a good synergism with salt. Variation in temperature will affect the dynamic and equilibrium interfacial tension, and increasing the temperature can shorten the time to reach the equilibrium and decrease the equilibrium interfacial tension in the range of experimental temperatures. With the addition of polyacrylamide (PAM), it takes longer to reach equilibrium, but this has little effect on the value of equilibrium interfacial tension.

“…The first report of this class of surfactants is a bis-quaternary ammonium dihalide surfactant [6]. The use of gemini surfactants covers the substantial homogeneous catalytic reactions along with solubilisation, emulsification, and many more technical applications in industries such as electro-decoating, stabilization of adhesive polymer latex, as an anti-friction agent, mining, paper manufacturing, preparation of surfactants including softeners, cosmetics, and most importantly, recent advancement in drug designing, synthesis, and application in medicine [7][8][9][10][11][12][13]. The recent demands of our civilization and endless advancement in industries trigger the research of enormous potential of substituting traditional monomeric surfactants.…”

Cationic gemini surfactants are a special class of second-generation smart surfactants. Since Menger first named them, gemini surfactants have drawn a wide and immense attraction from scientists throughout the whole world. These dimeric surfactants possess two or more hydrophilic with two or more hydrophobic head groups, chemically bonded with a linker, called the spacer group. These kinds of surfactants are used mainly in homogeneous catalytic reactions, as well as for solubilisation, emulsification, and many more technical applications. They are used in industries for electro-decoating, stabilization of adhesive polymer latex, antifriction agents, mining, paper manufacturing, preparation of surfactants including softeners, cosmetics, and most importantly, recent advancement in drug designing, synthesis, and application in medicine. The aim of this paper is to bring attention to the high performance second generation interfactants, with a focus on their synthesis, structure, types, and greener industrial application with high possibility of future prospect.
