摘要
乙二胺基乙磺酸钠是水性聚氨酯合成中重要的亲水性扩链剂,又可作为有机中间体、生化试剂应用于其它领域.采用乙二胺(EDA)和2-氯乙磺酸钠反应合成乙二胺基乙磺酸钠,由红外光谱(FTIR)、核磁氢谱(1HNMR)和碳谱(13CNMR)、X射线衍射(XRD)、元素分析等手段表征了产物的结构与特性.在EDA与2-氯乙磺酸钠物质的量比为6.5∶1时,合成产物中乙二胺基乙磺酸钠含量高达94.4%.产物极易溶于水,微溶于甲醇,乙醇,不溶于丙酮,N,N-二甲基甲酰胺,四氯化碳,氯仿等有机溶剂.
Aliphatic diamine sulphonate was synthesized by the reaction of ethylenediamine with sodium 2-chloroethanesulfonate. The products were characterized by means of FTIR, ^1H NMR, ^13C NMR, XRD, and elemental analysis. The content of aliphatic diamine sulphonate in the product was 94.4% when the molar ratio between ethylenediamine and sodium 2-chloroethanesulfonate was 6.5 ： 1. The product was more soluble in water, slightly soluble in methanol and ethanol, and insoluble in such organic solvent as acetone, DMF, CCl4, and CHCl3.
