摘　　要：采用无水乙二胺、月桂酸和氯乙酸为原料合成N-月桂酰基乙二胺三乙酸,通过正交实验确定了最佳实验条件,同时对产物的润湿力、乳化力和螯合能力等性能进行了研究。性能研究表明:产品泡沫稳定性能很好,29.2℃时,cmc=3.48 mmol/L,γ(cmc)=23.7 mN/m。Laurlc acid reacted with ethylenediamine and chloroacetic acid to synthesize N-lauryl-ethylenediamine-triacetic acid . By orthogonal experiment the optimum experiment condition was obtained. Property experiment showed good foam stability. The T （cmc） was 23.7 mN/m and cmc was 3.48 mmol/L at 29.2 ℃, Also, the wetting, emulsifying and chelating ability were studied.
