摘　　要：合成并表征了阳离子双子表面活性剂N,N′-双(十四烷基二甲基)-1、2-二溴化-乙二铵盐(C_(14)-2-_(14).2Br^-)。用布氏旋转粘度计测定其水溶液粘度,并考察了溶液浓度、温度、pH值以及添加剂(盐、单链表面活性剂、聚合物)加量对C_(14)-2-_(14).2Br^-水溶液粘度的影响。发现C_(14)-2-_(14).2Br^-具有较好的溶液增粘性,但其耐温性较差;提高溶液pH值,添加无机盐和阳离子聚合物均可提高C_(14)-2-_(14).2Br^-溶液的粘度,阳离子聚合物与C_(14)-2-_(14).2Br^-具有良好的协同配伍性;而添加表面活性剂、NaSal均使C_(14)-2-_(14).2Br^-溶液粘度急剧下降,NaSal引起C_(14)-2 -_(14)2Br^-水溶液粘度下降原因有待研究。Cationic Gemini surfactant,N,N'-bis (myristyl dimethyl)-1,2-dibromine ethylene diam- monium(C_(14)-2-_(14).2Br^-)was synthesized and char- acterized.Aqueous solution viscosity of C_(14)-2-_(14). 2Br^-was measured by means of Brook-Field progra- mable rheometer,and effects of solution concentration, temperature and pH as well as additive concentration on aqueous solution viscosity were investigated.It is found that C_(14)-2-_(14).2Br^-has better solution enhan- cing viscosity property but less heat-resisting,the so- lution viscosity will be enhanced by appending inorgan- ic salt and cationic polymer as well as increasing solu- tion pH.And C_(14)-2-_(14)-.2Br^-has better synergistic effect with cationic polymer in increasing solution vis- cosity,but the solution viscosity will be decreased by adding traditional surfactants and salicylic sodium.The mechanism that salicylic sodium decreases C_(14)-2-_(14). 2Br^-solution viscosity will be studied in next paper.
