Description
技术领域
本发明涉及涉及一种碳酰胺基双子阳离子表面活性剂及其制备方法和应用,属于精细化学品领域。
背景技术
随着表面活性剂的使用,其带来的环境污染也受到了广泛关注。双子(Gemini)表面活性剂通常具有更高的表面活性和更广泛的用途,与常规表面活性剂相比,使用量大大减少,已成为表面活性剂研究的热点领域。
表面活性剂使用面临的另一个问题是其在环境中降解性。为减缓其对环境的影响,生物易降解的表面活性剂不断涌现,如结构中含有酰胺键的分子在自然界中易于降解,属环境友好的表面活性剂。
通常表面活性剂的溶解度会随温度的下降而减小,在低温下出现沉淀将影响其使用效果。因此,较低Krafft点的表面活性剂具有较宽的温度适应范围,可方便储存、运输、复配和使用。
水中的农药会对环境造成很大影响,表面活性剂改性蒙脱土去除水中的除草剂双草醚可以有效避免其对水环境的污染。

本反应的反应温度在室温至溶剂回流温度之间进行均可,为加快反应,优选为回流温度下进行;反应时间为24~72h,优选为36~48h。
所述有机溶剂为极性溶剂,选自甲醇、乙醇、异丙醇、乙腈、丙酮、丁酮、四氢呋喃等中的一种或几种的混合,优选为乙醇、丙酮或乙腈。
本发明制备过程如下所示:
本发明采用的原料N,N′-双(3-二甲基氨基丙基)脲可按文献1给出的方法制备,也可采用其他的方法获得。

改性蒙脱土时,碳酰胺基双子阳离子表面活性剂的加入量为蒙脱土质量的0.5~1.2倍,优选0.8倍。改性时温度为常温~80℃,时间为3~6h。
改性后的蒙脱土需经离心、水洗涤、烘干、碾碎、过200目筛处理。
在去除水体中的农药双草醚时,农药双草醚的浓度范围为100~400mg/L,50mL水中加入改性蒙脱土量为0.1~0.3g,常温下震荡,操作时间为2~5h。
本发明制备的表面活性剂,经测试具有良好的表面活性、乳化性能以及低温适应性,可作为蒙脱土的改性剂,用于清除水中农药双草醚污染物。
