- W2388286974 abstract "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." @default.
