摘　　要：利用十四烷基二甲基叔胺、无水乙醇及1,4-二溴丁烷等原料,通过一步法合成了十四烷基阳离子双子新型表面活性剂。表面张力的测定结果表明,该新型表面活性剂具有较小的表面张力和较低的临界胶束浓度;界面张力的测定结果表明,该新型表面活性剂与大庆油田采油二厂原油之间的油/水界面张力最低可降至1×10^(-3)m N/m;另外,该新型表面活性剂还具有稳定的乳化性能和泡沫性能,并与普通表面活性剂有良好的协同作用。The tetradecyl cationic gemini surfaetant was synthesized by one-step method with dimethyl tetradecyl amine, ethyl alcohol and 1,4-dibromobutane as raw materials. The surface tension measurement result showed that the new type of surfactant had smaller surface tension and lower critical micelle concentration; the interfacial tension measurement result showed that the oil/water interfacial tension between the new type of surfactant and crude oil from the Second Oil Production Plant of Daqing Oilfietd could reduce to 10^-3 mN/m; besides, the new type surfactant also had stable emulsion property and foam property, and had good synergistic effect with common surfactant.
