一般說明

十二烷基三甲基溴化铵为单链表面活性剂。

應用

十二烷基三甲基溴化铵已用于评估在溶液表面的反离子分布和反离子互溶性之间的关系的研究。这是对含有普通表面活性剂离子但反离子不同的表面活性剂混合物推导出来的。 它也被用于研究用电导法、密度测量法和小角中子散射法研究它在整个水-二甲亚砜 (DMSO) 混合物组成范围内的胶束形成。

The micellization in mixed solvent was studied using conductimetry, density measurements (molar volumes), and small angle neutron scattering (SANS) to explore dodecyltrimethylammonium bromide (DTABr) micelle formation throughout the entire composition range of water-dimethylsulfoxide (DMSO) mixtures. As the concentration of DMSO

Polyelectrolytes with amphiphilic counterions, PEACs, are water insoluble because the amphiphiles self-assemble into highly charged micelles that strongly associate with the equally highly charged polyions. However, in the presence of water soluble cyclodextrins (CDs) that form inclusion complexes with the

Interactions between uncharged polymers and cationic surfactants are considered weaker than interactions with the anionic analogues. This work describes the binding occurring between methylcellulose (MC) and the cationic surfactant DTAB in aqueous medium. In the absence of salt, MC-DTAB exhibits
