Microemulsions as a medium in chemical kinetics, II. The I⁻ + S₂O₈⁼ and crystal Violet + OH⁻ reactions in different surfactant/oil/water microemulsions

Abstract

A kinetic study of the reactions I-+ SZOa= and CV' + OH-(CV = 4, 4', 4"-tris(dimethy-

Kinetics of the Formation of Nano-Sized Platinum Particles in Water-in-Oil Microemulsions

“…9a). An increased reactant concentration can be assumed to cause an increase in reaction rate, which has for instance been demonstrated for the oxidation of iodide by persulfate using either AOT (25,26) or sodium dodecylsulfate (27) as surfactant. However, as Reaction [8] proceeds the concentration of chloride ions will increase and in an AOT-based system the Cl − ions will interact repulsively with the sulfonate headgroups, resulting in a local increase also of Cl − ions in the core of the water droplet (see Fig.…”

Micellar Effects on the Reaction S2O82−+ Fe(CN)4(bpy)2−

“…We Conductivity measurements. Conductivity was measured have been interested in the study of inorganic electron transwith a Crison microCM 2201 conductimeter connected to a fer and ligand substitution reactions in micellar solutions of water flow thermostat maintained at 298.2 { 0.1 K. several surfactants, anionic, cationic, and nonionic (1)(2)(3)(4)(5)(6).…”

Influence of colloid suspensions of humic acids on the alkaline hydrolysis of N‐methyl‐N‐nitroso‐p‐toluene sulfonamide

“…In fact, one [47] of the first studies on micellar catalysis and inhibition referred to the alkaline fading of CV, and these reactions were later used very often for studies in normal micelles and other self-assembly colloids [48][49][50][51]. The reaction is typically a "well-behaved" one and has become an interesting source of information on the role of the different factors that affect overall reactivity in normal micelles (i.e., compartmentalization of the reagents and characteristics of the micellar reaction medium).…”
