Abstract: Three reactive zwitterionic surfactants (M10,M12 and M14) with different alkyl chain lengths had been synthesized by using N,N-dimethyl-1,3-propanediamine,maleic anhydride and alkyl bromide as principal raw materials.The compounds had been characterized by FT-IR,ESI-MS and 1H-NMR.The critical micelle concentration (cmc) and the corresponding surface tension (γcmc) of M10,M12 and M14 in aqueous solution were measured at 25 ℃ by surface tensiometer.The foam properties,wetting properties,emulsifying properties and solubility were also determined.Results show that the cmc of M10,M12 and M14 at 25 ℃ are 5.89×10-4,2.63×10-4 and 1.35×10-4 mol/L,and their γcmc values are 31.26,28.79 and 26.87 mN/m,respectively.The foam properties,emulsifying properties and wetting properties of M14 are better than those of M10 and M12,while the solubility of M14 is slightly worse than that of M10 and M12.
