月桂酸单乙醇酰胺硫酸酯盐的合成与性能

Synthesis and performance of lauric acid monoethanolamine sulfate

通过一系列反应合成了月桂酸单乙醇酰胺硫酸酯盐(以下简称C12MSN),测定了在303 K下的表面化学性质及泡沫、去污、润湿等应用性能,研究了C12MSN与酯基Gemin i型季铵盐(以下简称Ⅱ-12-3)溶液复配体系的性质。结果显示,C12MSN的临界胶束浓度是2.79×10-3mol/L,其表面张力为25.42 mN/m,泡沫性好。发现n(C12MSN)∶n(Ⅱ-12-3)=7∶3复配时有较好的协同效应。

Ethanol lauric acid amide sulfate salt（C12MSN） synthesized through a series of reaction measured the surface chemical properties and foam,cleansing,wetting and other application performance at 303 K,research C12MSN with ester-type season Gemini ammonium salt（Ⅱ-12-3） solution of complex system in nature.The results showed that,the critical micelle concentration of C12MSN is 2.79×10^-3 mol/L,the surface tension is 25.42 mN/m,foam is good.Found that when n（C12MSN） ∶n（Ⅱ-12-3）=7 ∶3,the mixtures always have good synergy.
