十二烷基二甲基氧化叔胺与月桂醇聚氧乙烯醚硫酸钠二元复配物的特性研究

Research on Properties of Binary Mixtures of Dodecyl Dimethyl Amine Oxide and Sodium Lauryl Ether Sulfate

选择十二烷基二甲基氧化胺(OB-2)与月桂醇聚氧乙烯醚硫酸钠(AES)按各种比例二元复配,测定其表面张力、发泡性能、泡沫持久力、粘度等特性数据。结果显示OB-2占65%时配合物的表面张力最小,OB-2占70%时发泡力和泡沫持久力最强;OB-2低于20%时溶液粘度变化不大。

Sodium lauryl ether sulfate and dodecyl dimethyl amine oxide（OB-2） were mixed in different proportions.Then surface tension,foaming property,foaming sustaining power and viscosity of these binary mixtures were determined.The result shows that the binary mixture with 65% OB-2 has the lowest surface tension,and the binary mixture with 70% OB-2 has the highest foaming property and foaming sustaining power.On the other hand,viscosities of the binary mixtures with different OB-2 content have similar level when OB-2 content is below 20%.
