一种新型的双子表面活性剂的合成

Synthesis of A New Type of Gemini Surfactants

以脂肪醇为原料与氢溴酸反应得到卤代烃,后者与4,4′—联吡啶作用即得到双子季铵盐.通过2步反应合成了一种新型的双子表面活性剂,核磁共振氢谱和碳谱分析结果表明所得产物即为目标化合物.该合成方法简单,步骤少,产物易纯化,产率高.

A new type of gemini surfactants has been synthesized by 4,4′—bipyridyl and halogen hydrocarbons, the latter was prepared by refluxing aliphatic alcohol and hydrobromide. The structures have been confirmed by^1HNMR and^(13)CNMR. The method is rather simple, the compound easily purified and in high yield.
