Description

环境友好含氟非离子Gemini表面活性剂及其制备方法和应用
技术领域
本发明涉及含氟非离子Gemini表面活性剂技术领域,具体涉及一种环境友好含氟非离子Gemini表面活性剂及其制备方法和应用。
背景技术
含氟表面活性剂作为特种表面活性剂中重要的一类,是指碳氢表面活性剂碳氢链上的氢原子全部或部分被氟原子取代,形成以氟碳链为疏水基的一类表面活性剂。按亲水基极性的不同,可分为离子型含氟表面活性剂和非离子型含氟表面活性剂。相比于离子型含氟表面活性剂,非离子型含氟表面活性剂具有其独特的性能,比如在水中不电离,对溶液的pH值的变化和电解质的存在不敏感,可溶解在酸、碱的溶液中等。
氟碳键的特殊结构赋予了含氟表面活性剂具有常规表面活性剂不可比拟的性质:高表面活性、高化学稳定性、高耐热稳定性以及氟碳链既憎水又憎油的特性。但是,长氟碳链(连有氟的碳原子的个数大于等于8)的含氟化合物难以在环境中降解,并且具有生物积累性,会沿食物链在生物体内富集,危害人类健康。比如全氟辛烷磺酸(PFOS)在人体内的“半排出时间”长达8.7年,不但会造成呼吸系统的伤害,甚至会导致新生婴儿死亡。因此,研制性能优异且环境友好的含氟非离子表面活性剂具有十分重要的意义。
双子表面活性剂(Gemini)又称二聚表面活性剂,包含两条疏水链和两个亲水基团,通过与连接桥形成共价键连接而成,连接桥可以是聚亚甲基链、包含杂原子(N、O和S)的亚甲基链和刚性的芳香基团。自Bunton团队合成双溴化季铵盐Gemini表面活性剂以来,这类表面活性剂因其独特的性能而受到越来越多的关注。与传统表面活性剂相比,Gemini表面活性剂具有较低的临界胶束浓度(CMC)、较低的Krafft、特殊的流变性能和良好的润湿性。目前已有许多碳氢Gemini表面活性剂合成的报道,但对含氟Gemini表面活性剂的研究相对较少,尤其是含碳氟短链的非离子Gemini表面活性剂尚无报道。
因此,研制含碳氟短链的环境友好非离子Gemini表面活性剂具有十分重要的意义。
