| 摘 要： | 测定了阴离子双子表面活性剂8-4-8和12-4-12与不同油相间的界面张力,考察了不同油相和矿化度变化对油水界面张力的影响。结果表明,阴离子双子表面活性剂与不同油相的油水界面张力达到平衡的时间都比较短,界面张力稳定性较好;8-4-8在煤油的油水界面活性最好,而12-4-12在稀油的油水界面活性比混合油的好。矿化度增加(0~180 g/L)能有效降低阴离子双子表面活性剂的油水界面张力,说明阴离子双子表面活性剂8-4-8和12-4-12具有较好的耐盐性。

| Abstract: | The inteffacial tension between the anionic Gemini surfactants such as 8-4-8, 12-4-12 and the different oils is measured and the effect of different oil phase, temperature and salinity on the oil-water inteffaeial tension is investigated in this paper. The results show that the time to ,＇each the inteffaeial tension equilibrium for anionic Gemini surfactant with different oil phase is short and the dynamic inteffacial tension is stable. The inteffacial activity between the suffactant 8-4-8 and the kerosene is the best one in the three oil phases and the interfaeial activity between the suffactant 12-4-12 and the thin oil is better than that of the mix oil. The salinity increases （0 to 180 g,/l,） can effectively reduce the inteffaeial tension between the anion Gemini surfaetant and the thin oil. The anionic Gemini suffactants 8-4-8 and 12-4-12 all have good resistances to salt. |
