Quantitative Correlation between Counterion (X) Affinity to Cationic Micelles and X-Induced Micellar Growth for X = 2,4-; 2,5-; 2,6- and 3,4-Dichlorobenzoate Ions

Kinetics and Mechanism of Counterionic Salt-Catalysed Piperidinolysis of Anionic Phenyl Salicylate in the Presence of Cationic–Nonionic Mixed Micelles

“…Several studies have been published on the role of different inert salts in modifying the structural features of cationic micelles in aqueous solution and, directly or indirectly, it is believed that these salts influence the micellar structural growth [10][11][12]. In addition, some studies [13][14][15] reported possible quantitative correlations between the hexadecyltrimethylammonium bromide (HDAB) micellar binding constants and the counterion and/or temperature-induced micellar structural growth. These studies [13][14][15] and some related ones [16][17][18] used a semi-empirical kinetic (SEK) method to determine the values of the relative counterion binding constant, K X Br or R X Br (with R X Br = K X /K Br , where the values of HDAB micellar binding constants, K Br and K X , were derived from kinetic parameters obtained in the presence of micelles with different structural features) [19].…”

However, these reports lack information on reliable mechanism(s) of the effects of nonionic surfactants in the cationic micellar structural transition which opens up the possibility of optimising the use of mixed micelles in advanced technologies and industries [20].…”

Kinetics and Mechanism of Alkaline Hydrolysis of N-(o-Aminophenyl)Phthalimide in the Presence and Absence of Cationic Micelles and Sodium Salts of Aliphatic Acids

“…Globally, research on nanoscale structures such as micelles has become widespread in the science, engineering and medical fields [1][2][3]. The uniqueness of micelles is because of their viscoelastic behaviour [4][5][6] and, as a consequence, many physicochemical properties of these nanoparticles, at the molecular level [7], have been exploited for several decades [7,8]. Earlier reports revealed that the first technique used to detect the occurrence of ion exchange between counterions at the ionic micellar surface was kinetic study [9][10][11].…”
