摘要: 采用液-液萃取法从胜利油田用石油磺酸盐原样品中分离纯化出常规和亲油性石油磺酸盐样品, 对
该样品进行了液相色谱分析、电喷雾质谱分析和亲水亲油平衡值测定, 并采用旋转滴法考察了它们降低油/水界面
张力的能力。结果表明, 亲油性较强的石油磺酸盐与常规石油磺酸盐的组成不同, 其主要以单磺酸盐的形式存在,
而常规石油磺酸盐中单、双磺酸盐含量相当。在界面活性方面, 亲油性石油磺酸盐降低界面张力的能力远远低于常
规石油磺酸盐, 而且其单元体系和二元复配体系均不能达到超低界面张力;而常规石油磺酸盐复配体系可以将界面
张力降至10-4 mN/ m 。同时对石油磺酸盐的组成结构与界面活性之间的相互关系进行了初步探讨。

Abstract:

Regular and hydrophobic petroleum sulfonates were extracted and purified from the crude samples of petroleum sulfonates used in shengli oilfield by liquid-liquid extraction method. Analysis of these substances using liquid chromatography, mass spectrometry and determination of hydrophile-lipophile balance values were completed. Meanwhile, interfacial tension values of oil/water system respectively consisted of regular and hydrophobic sulfonates were measured by rotated dropping method. The results show that hydrophobic sulfoantes are different from regular sulfonates in composition, and it mainly consists of mono sulfonates, while the contents of mono and disulfoantes in regular sulfonates are similar. Meanwhile its interfacial activity is much lower than that of regular sulfonates, and it can not obtain ultralow interfacial tension values, not only for unit but also for mixed systems. While mixed systems of regular sulfoantes can decrease interfacial tension values to 10-4 mN/m. Besides, the relationship between the structure of petroleum sulfonates and their interfacial activities was discussed.
