摘要
以N,N-二甲基-1,3-丙二胺、顺丁烯二酸酐和烷基溴为主要原料,合成了不同烷基链长的反应型两性表面活性剂M10、M12和M14。经FT-IR、ESI-MS、~1H-NMR验证了目标产物,测定了M10、M12和M14水溶液中的临界胶束浓度(cmc)和相应的表面张力(γ_(cmc))及泡沫、润湿、乳化和溶解性能。结果表明,M10、M12、M14的cmc在25℃分别为5.89×10^(-4),2.63×10^(-4)和1.35×10^(-4)mol/L,γ_(cmc)分别为31.26,28.79和26.87 mN/m;M14的泡沫、乳化和润湿性能好于M10、M12,溶解性能比M10、M12的稍差。
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 γcmcvalues 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.
