通过不同碳链长度的正构烷烃与石油磺酸盐 非离子表面活性剂和石油磺酸盐 十二烷基苯磺酸钠体系之间动态界面张力的研究 ,发现混合表面活性剂在降低界面张力能力方面的协同效应不仅与表面活性剂分子之间的相互作用有关 ,而且与油相性质密切相关。从表面活性剂分子亲水能力和亲油能力方面为协同效应提出了一个新的解释 Through the study of the dynamic interfacial tension between normal paraffins with different carbon chain lengths, petroleum sulfonate nonionic surfactant and petroleum sulfonate sodium dodecyl benzene sulfonate system, it is found that the mixed surfactants can reduce the interfacial tension The synergistic effect in terms of capacity is not only related to the interaction between surfactant molecules, but also to the nature of the oil phase. A new explanation for the synergistic effect from the hydrophilic and oleophilic capabilities of surfactant molecules
