| 摘 要： | 以壬基酚生产过程中的副产物二壬基酚为原料,合成了氧丙烯平均链节数为5.01的二壬基酚聚氧丙烯醚磺酸盐(DNPPS).界面张力测定表明:DNPPS/桩西稠油的动态界面张力平衡值为0.13mN/m,比以壬基酚为原料合成的具有相似氧乙烯链节的其他非离子-阴离子表面活性剂动态平衡界面张力都低.为进一步降低DNPPS/桩西稠油的界面张力,将DNPPS与碳酸钠进行了复配.发现当体系中Na2CO3与DNPPS质量比为10∶1左右时,二者之间有明显的协同效应;在Na2CO3质量分数为0.1%的复配体系中添加质量分数为0.005%～0.010%的DNPPS,可使界面张力降低到10-4mN/m以下.研究对稠油化学驱有指导意义,也为二壬基酚的应用提供了新途径.

| Abstract: | Dinonylphenol polyoxypropylene ether sulfonates (DNPPS),whose average link number of oxypropylene is 5.01,is synthesized using dinonylphenol,which is the by-product in the production of nonylphenol.The average dynamic interfacial tension (IFT) between DNPPS and Zhuangxi crude oil is 0.13 mN/m,which is lower than those of other nonionic-anionic surfactants synthesized using nonylphenol containing similar link number of oxyethylene.In order to further reduce dynamic interfacial tension (IFT) between DNPPS and... |
