In order to explore the application of piperazine-based Gemini surfactants in the fields of enhanced oil recovery(EOR),preparation of new materials and biotechnology,two Gemini surfactants Ⅰ and Ⅴ,one Bola surfactant Ⅱ containing two kinds of counter ions and a macrocyclic surfactant Ⅲ were synthesized.The critical micelle concentration(CMC) of Ⅰ is 6.47×10~(-4) mol/L,which is better than traditional surfactants.The CMC of Ⅴ is 1.17×10~(-3) mol/L,which indicates that the more hydrophobic chains on...

In order to explore the application of piperazine-based Gemini surfactants in the fields of enhanced oil recovery(EOR),preparation of new materials and biotechnology,two Gemini surfactants Ⅰ and Ⅴ,one Bola surfactant Ⅱ containing two kinds of counter ions and a macrocyclic surfactant Ⅲ were synthesized.The critical micelle concentration(CMC) of Ⅰ is 6.47×10~(-4) mol/L,which is better than traditional surfactants.The CMC of Ⅴ is 1.17×10~(-3) mol/L,which indicates that the more hydrophobic chains on a spacer of limited length,the lower its surface activity.Ⅱ and Ⅲ can be used in biotechnology and can be used as template in preparation of new materials because of its good water solubility.Calculation carried out by MM2 energy minimization shows that compound with more hydrophobic chains in a spacer of limited length is difficult to be synthesized.The good water solubility of Ⅲ is explained by solvent accessible area.

为了探索哌嗪类双子表面活性剂在三次采油(EOR)、新材料制备及生物技术领域中的应用,合成了两个以哌嗪为基的双子表面活性剂Ⅰ和Ⅴ,一个含有两种阴离子的Bola型表面活性剂Ⅱ和一个大环表面活性剂Ⅲ。表面张力测定结果显示,Ⅰ的临界胶束浓度(CMC)为6.47×10-4mol/L,优于传统的表面活性剂;Ⅴ的CMC为1.17×10-3mol/L,说明连接基团长度一定时,增加疏水链的数目,表面活性降低。Ⅱ和Ⅲ水溶性较好,可应用于生物技术领域或在新材料中作为模板剂。MM2能量最小法计算结果显示,在有限长连接基团中引入较多疏水链的化合物不易合成。用溶剂可接触面积说明了Ⅲ水溶性较好的原因。
