A trimericquaternaryammonium salt surfactant containing polyoxyethylene chains was synthesized from fatty alcohol polyoxyethyleneether, pentamethyldiethylenetriamine and thionyl chloride by a two‐step process. Its chemical structure was characterized, and the surfaceactivity in aqueous solution was studied at different temperatures. The results showed that when the concentration attains the CMC
通过两步法,由脂肪醇聚氧乙烯醚,五甲基二亚乙基三胺和亚硫酰氯合成了一种含聚氧乙烯链的三元季铵盐表面活性剂。表征了其化学结构,并研究了在不同温度下水溶液的表面活性。结果表明,当浓度达到CMC(1.0 mmol / L)时,在25°C下的表面张力为38.9 mN m -1,电导率为105.3μScm -1。这些表明含有聚氧乙烯链的三聚季铵盐表面活性剂表现出高的表面活性并有效地降低了水的表面张力。
