Synthesis methods and technological processes for preparation of gemini surfactants were systemically described in details. In line with the features of their chemical structure and performance, they were classified, compared and summed up as four categories, namely anionic, cationic, nonionic and amphoteric gemini surfactants. Together with the introduction of recent progress in the synthesis of gemini surfactants, the trends for the future development in this field were prospected.%针对双子表面活性剂的合成方法和制备过程,遵循阳离子型、阴离子型、非离子型和两性离子型为主要类别,按照其结构特点分门别类地进行比较和归纳,阐述了双子表面活性剂的合成研究情况,展望了其合成发展方向.
