摘要: 以油酸酰胺丙基二甲基胺、1,3-二氯-2-丙醇、1,4-二溴-2-丁烯和1,4-二溴丁烷为原料,分别合成了3种不同连接基团的油酸酰胺基季铵盐阳离子Gemini表面活性剂GS-1、GS-2和GS-3。 通过傅里叶变换红外光谱(FT-IR)和核磁共振波谱(1H NMR)对其结构进行表征,并对其Krafft温度、表面活性、乳化性能、泡沫性能、润湿性等性能进行了测定。 结果表明,成功制备了3种Gemini表面活性剂GS-1、GS-2和GS-3,且其Krafft温度均小于0 ℃,为其低温环境下使用,仍然保持较高表面活性提供了理论可能性。 GS-1、GS-2和GS-3的临界胶束浓度(CMC)分别为7.7×10-5、7.08×10-5和2.63×10-6 mol/L,和预期结果一致,Gemini表面活性剂的CMC比传统的单链表面活性剂低1~2个数量级;另外,表面活性剂GS-1、GS-2和GS-3均表现出良好的表面活性、乳化性能和泡沫稳定性。

Abstract: Oleamide quaternary ammonium Gemini surfactants GS-1, GS-2, GS-3 were synthesized by the reaction of Oleamide propyl dimethylamine and 1,3-dichloro-2-propanol, 1,4-dibromo-2-butene and 1,4-dibromo-butane, respectively. The structures of GS-1, GS-2, and GS-3 were characterized by Fourier-transform infrared (FT-IR) spectrometry and proton nuclear magnetic resonance (1H NMR), and their Krafft temperature, surface activity, emulsification performance, foam performance, and wettability were measured. The results show that three kinds of Gemini surfactants GS-1, GS-2, GS-3 are successfully prepared, and their Krafft temperatures are all less than 0 ℃, which provides a theoretical possibility for their use in low temperature environments with maintained high surface activity. Then, the critical micelle concentration (CMC) values of GS-1, GS-2, GS-3 are 7.7×10-5, 7.08×10-5, and 2.63×10-6 mol/L, respectively, which are consistent with the expected results. The CMC value of the Gemini surfactant is 1~2 orders of magnitude lower than that of the conventional surfactant single alkyl chain. In addition, the synthesized surfactants all show good surface a ctivity, emulsifying properties, and the ability to stabilize foam.
