Abstract
2-(Decanoyl-{2-[decanoyl-(2-sulfo-ethyl)-amino]-ethyl}-amino)-ethanesulfonic sodium is a new kind of Gemini surfactant.It was obtained from ethylenediamine,ethenesulfonic sodium and decanoic acid as primary materials through addition and acylation.The structure of the final product was proved by IR and 1H NMR.The optimum reaction conditions were as follows: n(intermediate) ∶n(decanoyl chloride) is 1∶2.1,reaction temperature 10 ℃ and reaction time 5 h,acetone and H2O as solvent.
