摘　　要：分子结构是双子表面活性剂的合成设计的根本,若结构与性能之间存在一定规律,即可选择最佳合成方案优化产物的性能。该文参照了国家标准测试方法,系统研究了阴离子双子表面活性剂GS10-2-10、GS10-4-10、GS12-2-12、GS12-4-12的表面活性、起泡性、乳化性、增溶性、润湿性、抗硬水能力等变化规律,与传统单链表面活性剂十二烷基硫酸钠(SDS)进行了对比,并从分子结构上分析了原因。结果表明,该系列阴离子双子表面活性剂各项性能均明显优于传统表面活性剂SDS;而且在其他条件一定时,碳链和联结基团长度适度增加,均可增强双子表面活性剂的各项性能。Synthesis of Gemini surfactants is designed according to molecular structure, and optimum schemes can be chosen while there are regularity between structure and properties. On the basis of national standard test methods, this article systematically researched the various performances of series of Gemini surfactants （GS10-2-10, GS10-4-10, GS12-2-12, GS12-4-12）, including surface activity, foaming, emulsification, solubilization, wettability and anti-hard water capacity, making contrast with the traditional single-chain surfactant SDS and cause analysis. Results show that all performances of anionic surfactant are better then SDS. As the other conditions are fixed, the length of carbon chain and linking group is increased in a certain range and the corresponding performances of Gemini surfactant are improved.
