摘要
近年来,双子表面活性剂是国内外研究非常活跃的一类油田用新型表面活性剂,目前对双子表面活性剂研究主要集中在阴离子、阳离子表面活性剂上。而两性双子表面活性剂分子不同于阴、阳离子双子表面活性剂,它由两个双亲分子的离子头基经连接基团通过化学键连接而成,由于其结构特点,分子在空气水界面排列紧密,且它的溶解度受无机盐的影响较小,这使得双子表面活性剂与传统表面活性剂相比,其临界胶束浓度和表面张力小、表面活性高、具有较高的耐盐性。由此本文设计并合成了系列新型磺酸盐型两性双子表面活性剂,具体合成路线如下,并利用~1H-NMR和FT-IR对其结构进行了表征,通过滴体积法对其表面性能进行了系统的测定,利用分子动力学法(MD)对其在气液界面的聚集行为进行了研究。
zwitterionic Gemini surfactants contained two amphoteric hydrophilic groups via linking group connected by chemical bonds,this made the Gemini surfactant has lower cmc,higher surface activity and higher salt tolerance than traditional surfactants.In this paper,we designed and synthesized a series of novel sulfonate-type zwitterionic Gemini surfactants.H-NMR and FT-IR were used to characterized its structure and through drop volume method was used to study its surface properties,in addition,MD was used to investigated the aggregation behavior at gas-liquid interface.
