摘要
以精细合成辛基酚为原料制得磺基甜菜碱型表面活性剂;利用表面张力仪对其性能进行测试,得出该表面活性剂具有较低的界面张力(10^(-3)mN/m)、良好的表面性能(临界胶束浓度为1.58×10^(-3)mol/L,临界表面张力为28.39 mN/m),以及优异的乳化性能和吸附性能。这对于油田现场提高采收率具有一定的指导应用。
A sulphobetaine surfactant was prepared with finely synthesized octylphenol as the material,and its properties were measured with a surface tension meter. It was found that this surfactant has small interfacial tension（ 1. 5 × 10^（-3）m N/m）,good surface property（ its critical micelle concentration being 1. 58 × 10^（-3）mol/L and its critical surface tension being 28. 39 m N/m）,and excellent emulsification and adsorption properties. It can be used to enhance oil recovery in oilfield.
