Solution behaviour of Aerosol OT in non-polar solvents

The internal structure of poly(methyl methacrylate) latexes in nonpolar solvents

“…Dispersions of colloids in nonpolar solvents are prevalent in soft matter nanoscience [1][2][3][4][5][6][7][8][9][10][11][12]. The significance of such dispersions can be appreciated by considering the many various industrial sectors that make use of them, which include petrochemicals [13], lubricants [7,14,15], reprography [4,5], inkjet printing [5], magnetic recording media [4], rheological fluids [16,17], and electronic displays [18][19][20][21].…”

Binding of o-nitroaniline to nonaqueous AOT reverse micelles

“…[4][5][6][7][8][9] Among the surfactants capable of forming these aggregates, sodium 1,4-bis(2-ethylhexyl)sulfosuccinate (AOT, Scheme 1) is one of the most used. 10 Solutions of AOT in nonpolar solvents have the remarkable ability to solubilize a large amount of water with values of W 0 as large as 40 to 60, 11,12 depending on the surrounding nonpolar medium, the solute and the temperature.…”

“…13 Consequently, solubilization of substrates in micellar aggregates plays an important role in biological and industrial processes. 10 The main driving forces responsible for the solute distribution between the organized assembly and the organic medium are considered to be mainly hydrophobic effects and hydrogen bond interactions. 14 However, other effects such as chemical and electrostatic interactions must be considered when charges 15 or zwitterionic molecules 16 are involved.…”

Kinetics and mechanism for the reaction of 1-chloro-2,4-dinitrobenzene with n-butylamine and piperidine in AOT/n-hexane/water reverse micelles

“…The reverse micellar solution can dissolve large amount of water with the formation of discrete droplet reverse micelles or bicontinuos reverse micelles. 3,4 The size of the droplets depends only on water concentration defined as the water-tosurfactant molar ratio W 0 (W 0 = [H 2 O]/[AOT]). The micellar pseudophase becomes a nanoreactor the size of which can be readily varied by choosing the experimental conditions, such as the concentration of surfactant and water, the strength of surfactant-water interaction, the size of the water pool, the microscopic viscosity and the polarity of the aqueous interior control.…”

“…4,5 The effect of AOT reverse micelles on a wide variety of chemical reactions has been recently reviewed. 3 Presently the kinetic models that allow interpreting intrinsic reactivity constants in these media are still scarce. 6 For a number of years we have been interested in bimolecular aromatic nucleophilic substitutions (SNAr) reactions between several nitro substituted aromatic substrates and aliphatic amines in n-hexane 7.8 and other non-polar 9 and polar aprotic solvents.…”
