摘　　要：用无水乙二胺、1-溴-十六烷和氯乙酸为原料,合成N-十六烷基乙二胺三乙酸钠,以提高阴离子表面活性剂在硬水中的稳定性。性能研究表明:它在硬水中的稳定性达到4级,cmc为2 13mmol·dm-3,γcmc=34.7mN·m-1。对产物的润湿力、分散力、乳化力等其他性能也进行了研究。Trisodium N-hexadecyl ethylenediamine triacetate was synthesized from anhydrous ethylenediamine,1-Br-hexadecane and chloroacetic acid.This chemical is often used for improving the stability of anionic surfactant in hard water. Property study showed that the stability of the product in hard water is grade 4 ,its cmc is 2.13 mmol·dm^(-3),γ_(cmc) is 34.7 mN·m^(-1). Other properties such as wetting power,dispersing power and foaming power etc were studied,too.
