The hydration of dodecyltrimethylammonium (DTAB) micelles is reinterpreted in light of the results of the companion paper (immediately preceding this paper) that showed that the location of the spin probe 16-doxylstearic acid methyl ester (16DSE) changes as a function of the aggregation number, N, of anionic micelles, i.e, that it does not conform to ...

Dodecyltrimethylammonium bromide-disodium dodecanephosphonate mixed micelles
Colloid & Polymer Science, 1999The aqueous catanionic system dodecyltrimethylammonium bromide (DTAB)–disodiumdodecanephosphonate (DSDP) was studied by potentiometry, conductivity, surface tension, spectrometry and dye solubilization. No precipitation of neutral salts was found in the entire range of compositions studied. Up to four transitions were detected. The first transition, at

The dodecyltrimethylammonium bromide (DTAB)–didodecyldimethylammonium bromide (DDAB)–water system was studied to elucidate whether the mixed surfactant aggregates are mainly micelles or vesicles, and whether the surfactant–surfactant interaction is ideal or not.

Bulletin of the Chemical Society of Japan, 1999
Abstract The conductances of tetradecyltrimethylammonium bromide (TTAB) + dodecyltrimethylammonium bromide (DTAB) mixtures over the entire mole fraction range of TTAB (αTTAB) were measured in pure water as well as in the presence of various aqueous ethylene glycol oligomers containing 5 and 10 wt% of each additive in their respective ...

Polymer Bulletin, 1999
Polymerization of vinyl acetate (VA) in three component oil/water (o/w) microemulsions stabilized with a mixture of two cationic surfactants (DTAB/DDAB in a weight ratio of 3), was carried out at 40, 50 and 60°C using a water soluble initiator, V-50.

Langmuir, 2006
Here, we report on a new aspect of the adsorption of Br- on the surface of gold. The adsorption of dodecyltrimethylammonium bromide (C12TABr) from aqueous solutions onto macroporous gold particles was studied by continuous flow frontal analysis solid/liquid chromatography and flow adsorption microcalorimetry.

Thermodynamics of the interaction between n-dodecyltrimethylammonium bromide and catalases
Thermochimica Acta, 1989Abstract The thermodynamic parameters for the interaction of the cationic detergent n -dode-cyltrimethylammonium bromide (DTAB) with bovine liver catalase at pH 3.2, 6.4 and 10.0 and with Aspergillus niger catalase at pH 10.0 have been measured at 25° C by a combination of equilibrium dialysis to determine the Gibbs energies of detergent binding ...

Potentiometric Study on Interaction of Dodecyltrimethylammonium Bromide with α-Amylase
Bulletin of the Chemical Society of Japan, 2004Abstract The binding of dodecyltrimethylammonium bromide (DTAB) with α-amylase was investigated under various experimental conditions, such as pH, ionic strength, urea and protein concentration at 25 °C using surfactant membrane-selective electrodes as a fast and accurate method.

ETS-10 synthesized from gels with dodecyltrimethylammonium bromide
Journal of Thermal Analysis and Calorimetry, 2007The aim of this paper is to define the characteristics of crystalline phase ETS-10 obtained from gel with dodecyltrimethylammonium bromide, as an organic template. ETS-10 zeolites has been synthesised under hydrothermal conditions from gels of composition 5Na2O–3KF–TiO2–6.4HCl– xC12TMAB –7.45SiO2–197.5H2O (where x=0.0, 0.25, 0.55, 1.0 and 1.5) with ...

Solubilization of spiropyran in aqueous NaBr solutions of dodecyltrimethylammonium bromide
Colloids and Surfaces, 1992Abstract 1,3,3-Trimethylindolino-6′-nitrobenzopyrilospiran is solubilized in aqueous NaBr solutions of dodecyltrimethylammonium bromide (DTAB). The dye is soluble in solutions of DTAB having concentrations higher than the critical micelle concentration.
