Micellization and interfacial behavior of imidazolium-based ionic liquids in organic solvent–water mixtures

Influence of cationic and non-ionic surfactants on the kinetics of mixed hydrogen/tetrahydrofuran hydrates

“…Reduction in efficiency was attributed to the competition between the organic and surfactant molecules for positions at the air/liquid interface, as well as how organic molecules reduce hydrophobic interactions between the hydrophobic groups of surfactants resulting in lower adsorption tendencies of surfactant molecules. Similar trends in Π CMC , Γ max , A min and C 20 were also observed by Pino et al (2009) andStrobel et al (2007), when investigating the micellization and interfacial behavior of surfactants in polar organic solvent-water mixtures. This could explain why surfactants are observed to be effective in promoting the formation of hydrates from pure water, as compared to from THF-water solutions.…”

Aggregation behavior of a chiral long-chain ionic liquid in aqueous solution

“…ILs with long-chain substituent groups have been synthesized with high surface activity [15]. The aggregation behaviors of such surface active ILs have attracted the most attention in the colloid and interface fields; numerous aggregates formed by the surface active ILs have been investigated over the past years including microemulsions [16], lyotropic liquid crystals [17][18][19][20] as well as micelles [13,[21][22][23][24][25][26]. Long-chain IL-based aqueous micelles have exhibited relatively low critical micelle concentration (cmc) values when compared to traditional cationic surfactants of analogous structure [24].…”

Ionic liquids in enhancing the sensitivity of capillary electrophoresis: Off‐line and on‐line sample preconcentration techniques

“…As well, a higher percentage of organic solvent (MeOH or ACN) was needed to focus the more hydrophobic analytes (Fig. 7) [87,88].…”
