| Abstract: | Disodium N-acyl ethylenediamine diacetate was synthesized by reactions of methyl laurate,ethylenediamine and sodium chloacetate.With the single factor optimization method to study the influence factors of the reaction,the optimal synthesis conditions for N-lauroyl ethylenediamine were found as follows: n(methyl laurate)∶n(sodium methoxide)∶n(ethylenediamine)=1∶0.08∶8,reaction temperature 90 ℃ and reaction time 7 h.The optimal synthesis conditions for disodium N-lauroyl ethylenediamine diacetate were found as follows: n(N-lauroyl ethylenediamine)∶n(sodium chloroacetate)=1∶2.5,reaction temperature 75 ℃,reaction time 8 h,and pH=8-9,with the yield of 86.45%.Performance study indicates that disodium N-acyl ethylenediamine diacetate has good surface activity and certain chelating ability. |
