Surface adsorption and thermodynamic properties of mixed system of ionic liquid surfactants with cetyltrimethyl ammonium bromide

“…18,19 Different measurement technologies were used to obtain the needed surface activities and thermodynamics functions, such as a small-angle neutron scattering (SANS), 13,20 dynamic light scattering (DLS) and viscosity measurements, 17 conductivity, 12,21,22 surface tension measurements, 23 as well different analytical methods, FT-IR, 3 UV-visible spectrum, 22,24 uorescence spectroscopy, 4,22,25,26 isothermal titration calorimeter 25 and NMR technology. 27,28 Apart from the self-assemblies and applications of ILs surfactants in various elds, the aggregation behavior of 1-alkyl-3-methylimidazolium (C n mim + ) in water has been presented by many research groups. 13,15,29 The micellization behavior of the DTAB/bdmimCl system has been reported by Pal' group, 27 also including their related work on tetradecyltrimethylammonium bromide TTAB/C 5 mim/PF 6 system, 30 CTAB/bdmimBr system, 31 odmimCl/DTAB mixed system, 21 and TTAB/bdmimBr mixture.…”

The CMC values of the mixtures increase with increasing wt% IL content and temperature at the same IL concentration.…”

Effects of 1‐Alkyl‐(and 1‐Benzyl)‐2,3‐Dimethylimidazolium Ionic Liquids as Additives on the Micellar Behavior of Surfactant SB‐12

“…Earlier studies carried out on surfactant + ionic liquid systems were confined to 1,3‐dialkylsubstituted IL (Behera and Pandey, ; Inoue et al, ; Javadian et al, ; Pal and Chaudhary, ). In this regard, our research group thoroughly studied modulations in the aggregation properties of different ionic and nonionic surfactants upon addition of 1,2,3‐trialkylimidazolium IL (Pal and Pillania, , , , , , , , ).…”

Efficient method for the synthesis of 3-arylbenzoquinoline, pyranoquinoline, and thiopyranoquinoline derivatives using PEG1000-based dicationic acidic ionic liquid as recyclable catalyst via a one-pot multicomponent reaction

“…[14][15][16][17] Ionic liquids (ILs), as environmental friendly reaction media or catalysts, have attracted increasing attention because of their particular properties, for example negligible vapor pressure, wide liquid range, and high thermal stability, making them a greener alternative to volatile organic solvents. [18][19][20][21][22][23] In addition, some ILs have been found to be an efficient and recyclable catalysts for the MCRs. [24][25][26][27][28][29][30] To the best of our knowledge, there is no report on the application of PEG 1000 -DAIL as acid catalysts for the preparation of 3-arylbenzoquinoline, pyranoquinoline and thiopyranoquinoline derivatives.…”
