Synthesis, Aggregation Behavior, Interfacial Properties and Oil Displacement Performance of a Maleic Anhydride-Derived Nonionic Gemini Surfactant.
To enhance the recovery efficiency of heavy oil, a nonionic Gemini surfactant (MOP-10) was successfully synthesized through a one-step reaction between maleic anhydride and octylphenol polyoxyethylene ether (OP-10). The surfactants before and after modification were systematically characterized and analyzed by means of...
