一般描述
十二烷基三甲基溴化铵为单链表面活性剂。
应用
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
