| 摘 要： | 以正癸酸及N-羟乙基乙二胺为原料,采用两步法合成了不同加水顺序条件下癸酸咪唑啉两性表面活性剂(简称DIAS).以红外谱图对2-壬基-N-羟乙基咪唑啉(化合物1)结构进行跟踪,对样品总固含量、氯化钠含量进行了测定并计算了样品有效物含量.通过对样品表面张力和泡沫力的测定,探讨了2-壬基-N-羟乙基咪唑啉两性化时加水顺序对样品的性能影响,结果表明DIAS合成中,两性化时先加水所得样品2b有效物含量、CMC值和泡沫力均略高于两性化时后加水所得样品2 a相应的各参数值.

| Abstract: | The decanoic acid imidazoline amphoteric surfactants(DIAS) were synthesized from n-decanoic acid and N-hydroxyethyl ethylenediamine under different water-added sequence by two-steps method.The structure of 2-nonyl-N-hydroxyethyl imidzoline was determined by IR.It was given total solid content 、 NaCl content and the effective substance content.The performaces of surface tension and foaming power of examples were also determined.The influence on the performance of water-added sequence of 2-nonyl-N-hydroxyethyl imidzoline was studied.It has shown the example 2b was higher. |
