Abstract
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.
