| 摘 要： | 分别测定了3种不同氧乙基(EO)数的十六烷基聚氧乙烯醚磺酸钠C16EnSO(n=3,5,7)水溶液的表面张力、临界胶束浓度、界面张力、乳化能力及模拟驱油率;利用Klett光电比色仪评价了表面活性剂水溶液的乳化能力.结果显示,随着EO数的增加,C16EnSO的表面活性呈单调型变化,而界面张力、润湿力、乳化力、模拟驱油率呈类似V型变化;C16EnSO及C16EnSO水溶液与胜利孤东原油间的界面张力达到10-2mN·m-1数量级,但EO数大于7后,界面张力明显升高;界面张力越低,润湿及乳化能力越好,相应地模拟驱油率越高,但润湿及乳化能力对模拟驱油率的影响程度似乎高于界面张力. |
| 关 键 词： | 十六烷基聚氧乙烯醚磺酸钠 表面活性 模拟驱油率 |

| Abstract: | Surface tension,critical micelle concentration,interfacial tension,emulsifying power and mimic oil recovery efficiency of aqueous solution of three kinds of surfactant,sodium polyethoxylated hexadecanol sulfonates with different number of EO groups(C16EnSO,n=3,5,7) were measured individually.Emulsifying power of the surfactant was evaluated using Klett photoelectric colorimeter.The results showed that:(1) as EO number of C16EnSO increased,surface activity increases accordingly towards a single direction;whi... |
