摘要
以联吡啶和溴代烷为主要原料,在乙醇溶剂中反应,合成双子表面活性剂N,N′-二烷基-溴代联吡啶。用红外光谱和核磁共振对目标产物进行了结构表征。20℃时目标产物水溶液的临界胶束浓度(CMC)可达0.5 mmol/L,在此浓度下对应的表面张力(γ_(cmc))为23.2 mN/m。合成方法简单,反应条件温和,操作简便,协同性能优良。
A new gemini surfactant N, N＇ -dialkyl -bromodipyridyl was synthesized from dipyridyl and 1 - bromo alkane in alcohol solution. The structure of the product was characterized by IR and ^1 HNMR. The data showing surface activity of the aqueous solution of the product at 20℃ were as follows： critical micelle concentration 0.5 mmol/L, surface tension 23.2 mN/m. The synthesis method was simple with mild reaction conditions and easy operation. There was obvious synergism between the above surfactant and SDS.
