摘　　要：合成了一种阴离子型Gemini表面活性剂N,N′-双棕榈酰基乙二胺二丙酸钠,利用红外光谱和核磁共振谱图表征了其结构.以合成的Gemini表面活性剂为主要原料,与非离子表面活性剂等复配制备了精练剂,探讨了精练剂的应用性能.结果表明:Gemini表面活性剂具有优异的表面活性,精练剂用于棉织物的精练,具有良好的效果.An anionic Gemini surfactant, N,N′-double palmityl ethylenediamine sodium propionate, was synthesized, and the structure was characterized by IR and HNMR. Scouring agent was prepared by mixing the synthesized Gemini surfactant and nonionic surfactant, and the application performance was discussed. The results showed that Gemini surfactant had excel ent surface activity. The scouring agent had good result in cotton fabric scouring.
