Counterion specificity of the micelle surface and its implications on micellar catalysis
(1996)
Dodecyltrimethylammonium bromide Dodecyltrimethylammonium hydroxide water mixtures were studied with ion-selective electrodes, and the aggregation behavior, degree of ionization of the micelles and the distribution constants ...
Mesoporous silica-titania composed materials
(Academic Press Inc Elsevier Science, 2006-08)
Titania mesosized particles were obtained by TiCl4 hydrolysis in Aerosol OT/water/n-hexane microemulsion. These particles were incorporated in surfactant templated silica mesoporous materials of MCM-41 and MCM-50 structures. ...
Synergism in mixtures of cationic surfactant and anionic copolymers
(2003)
Surface tension measurements have been made in aqueous solutions of anionic hemiesters of an alternating copolymer of maleic acid and styrene, MAS-n with n=0-12, in the presence of dodecyltrimethylammonium bromide, DTAB. ...
Miscibility of anhydrous cationic surfactant mixtures
(Elsevier Science, 2010-09)
Inverse gas chromatography (IGC) has been used for studying the miscibility of anhydrous cationic surfactant mixtures. Dodecyltrimethylammonium bromide (C12TAB), octadecyltrimethylammonium bromide (C18TAB) and their mixtures ...
Inverse microemulsion copolymerization of styrene and acrylic acid
(1991)
In this paper we report the first account on the copolymerization of a water-soluble monomer (acrylic acid) and a water-insoluble monomer (styrene) in ionic inverse microemulsions. Three different surfactants were used: ...
Inverse microemulsion copolymerization of styrene and acrylic acid
(1991)
In this paper we report the first account on the copolymerization of a water-soluble monomer (acrylic acid) and a water-insoluble monomer (styrene) in ionic inverse microemulsions. Three different surfactants were used: ...
Effect of Counterions on the Shape, Hydration, and Degree of Order at the Interface of Cationic Micelles: the Triflate Case
(Amer Chemical Soc, 2013-04-02)
Specific ion effects in surfactant solutions affect the properties of micelles. Dodecyltrimethylammonium chloride (DTAC), bromide (DTAB), and methanesulfonate (DTAMs) micelles are typically spherical, but some organic ...
Estudio de la solubilidad de gases en soluciones acuosas de sales de amonio cuaternario
(2013)
En este trabajo se determinó la solubilidad de argón y nitrógeno a 101325 Pa de presión parcial de gas en soluciones acuosas de bromuro de dodeciltrimetilamonio (BDTA), bromuro de tetrabutilamonio (BTBA), y bromuro de ...
Influence of the Surfactant Nature on the Occurrence of Self-Assembly between Rubber Particles and Thermally Reduced Graphite Oxide during the Preparation of Natural Rubber Nanocomposites
(Hindawi, 2015)
The natural rubber (NR) latex consists of polymer particles charged negatively due to the adsorbed phospholipids and proteins molecules. The addition of stable aqueous suspension of thermally reduced graphite oxide (TRGO) ...
Surface Activity of the Triflate Ion at the Air/Water Interface and Properties of N,N,N-Trimethyl-N-Dodecylammonium Triflate Aqueous Solutions
(AMER CHEMICAL SOC, 2011)
The surface activity of salts added to water is Air orders of magnitude lower than that of surfactants. Sodium trifluoromethanesulfonate (NaTf) produced a change in surface tension. with concentration, Delta gamma/Delta ...
