摘要: 以窄分布月桂醇聚氧乙烯(2)醚(AEO2)为原料经氯磺酸磺化中和合成了窄分布月桂醇聚氧乙烯(2)醚硫酸酯钠盐(AE2S)，适宜的合成工艺条件为：n(AEO2):n(HSO3Cl) =1:1.03，反应温度28℃，反应时间1h.经分离提纯后对产品的活性含量进行了测定，并对其表面张力、润湿性、乳化性、泡沫性、钙皂分散力、去污力和肤发刺激性进行了测试，同时与市售宽分布产品的物化性能进行了对比.结果表明，合成的窄分布AE2S阴离子活性含量为54.11%，气泡寿命为15s时的最低表面张力达27.2 mN/m，润湿性(0.1%溶液)51.4s，乳化性(液体石蜡)360s，泡沫性(0.1%溶液)45ml，钙皂分散力LSDP 10%，炭黑去污力(0.1%溶液)65.19%，蛋白去污力(0.1%溶液)69.42%，zein值为1.22g/L.与市售普通AES相比，在泡沫力、润湿力、乳化力、钙皂分散力和去污力等性能上都有显著的提高，合成的窄分布AE2S的zein值很低，与APG相近，表现出非常低的肤发刺激性.

Abstract: Lauryl polyoxyethylene ether sulfate with narrow molecular weight distribution (AE2S) was synthesized by using AEO2 with narrow molecular weight distribution as the starting material and the appropriate reaction conditions were shown as follows: n(fatty alcohol ether): n(chlorosulfonic acid) =1:1.03, the reactive temperature 28℃, and the reactive time 1h. The anion active content of the product was determined and its properties including surface tension, wetting, emulsification, foam, calcium soap dispersion force, detergency and skin irritation were measured.The results showed that anion active contents of AE2S is 54.11%,the minimum surface tension is 27.2 mN/m, and wettability is 51.4s, emulsifying capacity is 360s,foaming height is 45ml, LSDP is 10%, carbon black cloth detergency is 65.19%, protein fouling detergency is 69.42%,value of zein is 1.22g/L. Comparing with commercial AES, the synthesized AE2S showed an extremely low skin irritation and the various surface properties were significantly improved.-
