The interfacial tension between ABEPS solution and crude oil had been investigated. It was shown that ABEPS not only displayed outstanding salt resistance, but also good hard-water endurability, furthermore ultra low interfacial tension could be achieved without alkaline but proper amount NaCl in the water-crude oil system, which proved its excellent interfacial performance and better application prospects.

本论文还通过对ABEPS水溶液与原油之间的界面张力测定，发现ABEPS不仅具有出众的耐盐性能，而且具有良好的抗钙镁性能，合适的盐浓度下，表面活性剂水溶液与胜利原油之间可以在没有外加碱的情况下形成超低界面张力，说明这类表面活性剂具有良好的界面活性和潜在的应用前景。

The change of the position of the benzene ring has little effect on γ cmc-The interfacial tension behavior of this series of alkylbenzenesulfonates with carbon number 14,16,18 was investigated in alkane/aqueous system, it is found that alkylbenzenesulfonates of 16 total alkyl carbon number is the best.
