Erucyl sulfobetaine was synthesized by 3-chloro-2-hydyoxy propanesulfate and erucyl tertiary amines. First step, the optimum reaction condition was ratio of sodium bisulfite : sodium bisulfite = 1. 05 :1 ( mole ratio), temperature 85 ℃. Second step, erucyl tertiary amines:3 -chloro-2 -hydyoxy propanesulfate = 1:1, temperature 90℃, reaction time 6 h in isopropanol aqueous solution. The conversion reached 97%. The structure was confirmed by FT-IR. The dynamic interfacial tension (IFT) had been determined via Texas 500 spinning drop tensiometer. It might be a new type of surfactant in tertiary oil recovery.
