摘　　要：以无水对氨基苯磺酸、1,2-二溴乙烷、溴代十二烷等为主要原料制备了双阴离子(Gemini)表面活性剂N,N’-(十二烷基二对苯磺酸钠)乙二胺(HY-12)。采用IR光谱测试技术对目标产物的结构进行了初步鉴定,并考察了无机盐对HY-12表面活性的影响。该目标产物水溶液的cmc(5.0×10-4mol/L)是十二烷基磺酸钠的1/20,在临界胶束浓度下的γcmc(27.5 mN/m)比十二烷基磺酸钠(39.0 mN/m)低11.5 mN/m。目标产物与十二烷基三甲基溴化铵(DTAB)复配产生了较好的协同效应。Anionic gemini surfactant N, N＇ -（ dodecyl di-benzene sulfonate ） ethylene diamine （ HY-12 ） was synthesized by using sulfanilic acid, 1,2-dibromoethane and 1-bromododecane. Structure of the prod- uct was characterized by IR, and the effect of inorganic salts on surface activity of HY-12 was studied. The cmc value of aqueous solution of HY-12 achieves 5.0 × 10^4 mol/L,which is one-twentieth of that of sodium dodecyl sulphate. The γcmc of the product achieves 27.5 mN/m, which is 11.5 mN/m lower than that of sodium docecyl sulphate. The targeted product shows a synergic effect when it was blended with dodecyl trimethyl ammonium bromide （DTAB）.
