综述了酯基分别为连接基和疏水基的对称型季铵盐双子(Gemini)表面活性剂以及不对称酯基季铵盐Gemini表面活性剂的合成方法,并对合成产物的性能及应用进行了简单介绍,最后对酯基季铵盐Gemini表面活性剂的发展进行了展望。
Synthesis methods of symmetric and asymmetric Gemini quaternary ammonium salt surfactants with ester group (esterquats) as the spacer and as the hydrophobic group were summarized separately. Meanwhile, performance and applications of the synthesized Gemini esterquats were briefed. Future development of such category of surfactant was prospected.
