| 摘 要： | 利用叔胺的烷基化和多异氰酸酯与含活泼氢物质的质子转移反应,合成了一类新型双子(Gemini)表面活性剂DBAM,并通过红外光谱对其结构进行了分析,测定了表面活性和复配性能。结果表明,合成的双子表面活性剂DBAM结构独特,其临界胶束浓度低于离子头基联接相同碳原子数链的普通表面活性剂,具有较高活性和复配性能,可以有效降低水的表面张力。

| Abstract: | Novel Gemini surfactants, a series of DBAM, were synthesized by the alkylation of tertiary amine and the proton transfer reaction between polyisocyanate and reagent containing active hydrogen. The structure of DBAM - 12 was analyzed by IR spectrum. The surface activities and composition properties of DBAM were determined. The results showed that the gemini surfactants have special structure and excellent surface activities and composition properties. The CMC of DBAM were lower than that of general surfactants with the same number of carbon atoms liking with ionic head groups. |

| Keywords: | gemini surfactant surface activity critical micelle concentration spacer group |
