月桂醇聚氧乙烯醚的改性及性能测定

目的]对月桂醇聚氧乙烯醚（AEO3）进行改性来提高它的综合表面性能方法]用月桂醇、环氧乙烷合成月桂醇聚氧乙烯醚（AEO3）,再用AEO3与液体氯乙酸反应改性合成AEC。对AEO3、AEC、AES、十二烷基苯磺酸钠进行性能测定,并对各项性能进行比较。结果]AEC具有良好的表面活性,其润湿性、泡沫性（包括起泡性和泡沫稳定性）及去污性均比较好,表面张力较低,证明它是综合性能优良的阴离子表面活性剂。结论]用AEO3与液体氯乙酸反应改性合成的AEC综合表面性能优于AEO3。

Modification and Property Determination of Lauryl Polyoxyethylene Ether

Objective] The research aimed to improve the comprehensive surface performance of lauryl polyoxyethylene ether (AEO3) by means of modification.Method] AEO3 was synthesized from lauryl alcohol and epoxy ethane,which reacted with liquid chloroacetic acid to produce modified AEC.The prosperities of AEO3,AEC,AES,sodium dodecylbenzene sulfonate were determined and compared.Result] AEC had high surface performance,good wettability,good foam properties (including foamability and foam stability),good detergency ...
