摘要： 以十二胺、丙烯酸甲酯和对二氯苄为原料,三氯甲烷为溶剂,合成了双子表面活性剂N,N′-双十二烷基对苯二甲胺丙酸。采用1H NMR和13C NMR对其结构进行了表征。(25±1) ℃时pH对产物表面活性的影响研究结果表明:pH分别为8,10和12时,cmc分别为1.6×10-5,3.3×10-5和2.1×10-5 mol/L;γcmc分别为32.39,33.24和36.94 mN/m;pc20分别为2.56,2.14和2.09;Γmax分别为3.45×10-6,3.97×10-6和4.34×10-6 mol/m2;Amin分别为0.48,0.42和0.38 nm2。当pH=12时,随溶液温度升高,pc20和Amin增大,Γmax减小。

Abstract: Gemini surfactant N,N′-bis(dodecyl)-1,4-xylylene diamine propionate acid was synthesized from dodecylamine,methyl acrylate and p-xylylene dichloride as starting materials with trichloromethane as solvent.The chemical structure of the product was characterized by 1H NMR and 13C NMR.Performance of the product at (25±1) ℃ were studied and the results show that when the pH value is separately prepared at 8,10 and 12,the critical micellar concentration (cmc) is 1.6×10-5,3.3×10-5 and 2.1×10-5 mol/L respectively;the surface tension (γcmc) is 32.39,33.24 and 36.94 mN/m;the pc20 is 2.56,2.14 and 2.09;the Γmax is 3.45×10-6,3.97×10-6 and 4.34×10-6 mol/m2;the Amin is 0.48,0.42 and 0.38 nm2.When the pH value rises to 12,following the raise of temperature,the values of pc20 and Amin increase but the Γmax decreases.

Key words: Gemini surfactant, N,N′-bis(dodecyl)-1,4-xylylene diamine propionate acid, surface activity
