要 以烷基胺、1,3-二溴丙烷为主要原料,采用两步法合成了不同碳链长度(n=8、12、16)的N,N’-二烷基(8/12/16)-N,N’-二葡萄糖丙二酰胺非离子双子表面活性剂.通过FTIR与1HNMR对产物的结构进行了表征,用悬滴法对其表面张力进行了测定,用动态光散射对其粒度分布进行了测定,用改进Ross-Miles法对样品的泡沫性能进行了测定.结果表明:合成的葡萄耱酰胺非离子双子表面活性剂(8/12/16)的临界胶束浓度(cmc)及γcmc分别为5.627×10-3 mol/L、4.42×10-4 mol/L、2.96×10-3 mol/L和36.20 mN/m、30.22 mN/m、46.35mN/m;双子表面活性剂溶液粒径分布在130～1050nm;双子表面活性剂泡沫性能良好.
